As states have begun to legalize marijuana, its use has been more openly discussed. While the effects of other commonly used drugs, such as alcohol, have been studied extensively, the effects of marijuana – especially on developing babies during pregnancy – have been much less studied and less widely publicized. This relative silence from the scientific community has affected the public’s opinion on the safety of marijuana: 70 percent of U.S. women think there is “slight or no risk of harm” to the baby from using marijuana during pregnancy. Expectant mothers may use marijuana rather than prescription drugs during pregnancy to relieve pain because they feel “natural” or home remedies are a safer option than prescription drugs. However, just because something is “natural” doesn’t mean it is any safer or a better alternative to well-studied prescription drugs. This seems to be the case for marijuana. Given that marijuana is the most commonly used illicit drug during pregnancy, understanding its risks and impacts on the developing fetus is important.

Three large-scale longitudinal studies tracked how maternal cannabis use affected their child’s development, and they have had surprisingly consistent results. The Ottawa Prenatal Prospective Study surveyed 700 pregnant women who used marijuana in 1978 and has followed about 200 of those children into adulthood. The U.S.-based Maternal Health Practices and Child Development Study has studied 580 children of marijuana users from pregnancy through age 14. The Generation R study is tracking almost 8,000 children in the Netherlands.

Children of marijuana users were more impulsive and hyperactive, and exhibited behavioral issues, lower IQ scores, and memory problems when compared to children of non-users. These mental health problems persisted through their teenage years, where they were significantly more likely to have attention problems and depression. Marijuana-exposed children were also almost twice as likely to display delinquent behavior, such as drug use, by the age of 14 and were more than twice as likely to regularly use marijuana and tobacco as adults. The very consistent results between mice and human studies (summarized in the infographic from The Scientist below) highlights an increasing understanding of the impacts of marijuana use on development.

It’s important to note that some behavioral outcomes may not be completely related to fetal marijuana exposure. Children of marijuana users may have grown up in a different social environment with more lax views on drugs, contributing to their increased drug use.

As marijuana continues to be legalized, we should expect to see more studies on its health effects and safety.

  1. I’m curious how many if these mother’s had underlying genetic-based anxiety or ADHD related conditions themselves. How much is genetic-based vs exposure related.

    1. All the bad effects of marijuana are also everything I went through as a child into my teenage years. So I’m really doubtful this has any truth and reality. My mother didn’t smoke weed when she was pregnant and I still had all these issues.

        1. I would like to know that myself. I would think the brain of a 17 year old is still developing? My granddaughter started having headaches at the age of 3. I got her in with a neurologist and they found lesions on her brain. The dr told me this was caused from her mother smoking pot. She is now 11 and she has had issue for along time. Im just wondering if all her issues are due to her mother smoking pot while pregnant?

          1. I’m 17 and my mom was smoking pot when I was in the womb and I’m fine how old was the mom I think that has something to do with it my mom was 25

          2. The majority of cannabis smoked by those in the 70’s (in the UK at least) was mainly the resin type. This had far less if the psychotic chemical, THC, in than the ‘skunk’ cannabis used by most users in the UK now. It would be interesting to see the impact on children born to parents who smoke ‘skunk’ cannabis. Is sperm quality affected by a father’s use of ‘skunk’ cannabis? Pregnant women should be asked about their partner’s drug (or alcohol) use prior to conception.

            As others have stated, parents may also have had other diagnosed or undiagnosed conditions prior to smoking cannabis that may be genetically passed on to their children.

      1. I had my first child at 15. I don’t recommend it lol! However, I did fine. Mine are grown. All educated professional well rounded adults. Like everyone else not perfect but good. They’re decorated veterans and overall just good people. I myself went back to school at 20 got my GED and later got my Bachelor’s and more than three quarters through my Masters. All of my own children are gifted. I believe my circumstances are unique but not extraordinary. I went to insane lengths to get through school and get my children there too. I give more than half the credit to them having a great dad. Always loving kind involved and rock steady. Pot effects one’s motivation and can impact learning ability. If it is managed in a truly recreational manner it’s acceptable to use in moderation. When one has already been at work, done their daily duties, and no longer on anyone’s time, there’s no harm in enjoying a little marijuana. And the same goes for parenting it shouldn’t be done around the children. But…that’s a hindsight statement! Lol It didn’t harm mine but probably didn’t help either. And it is the one thing I’d do differently . We have 4 children 2 smoke 2 don’t . The 2 who do, are veterans and have a prescription for PTSD, which I’m certain they have now.

        1. I had my first child at 14, but I don’t agree with you. I recommend it, I think it was totally cool. I named him Elon, then I got bored so I put him next to a homeless dog and left him there lmao

      2. Agreed! This is kind of a whack “study” … many people with anxiety issues use marijuana. How do we know their children are t just inheriting this?

      3. You seem to be a case of Nuture VS. Nature. My opinion…Nature over ruled your Nuture. Society played a Strong role. My opinion is regarding your LACK of Nuture… Planted Roots (so to speak), As in,; Knowing exactly whom you are & the values, morals, etc. that may have been instilled.

    2. My husband had and I had different issues growing up from above. His mom and my mom definitely didn’t smoke weed. So it really doesn’t make a difference. I have many friends that told me their parents smoked weed during pregnancy and they are successful, smart individuals. More research needs to be done.
      I think using cannabis is better than taking a ton of prescription drugs sold to you by pharmaceutical companies that are owned by the wealthiest and scary powerful families! It’s all a conspiracy!

      1. I can see once in a while but my niece smoked daily and her infant was severely delayed and it cause cause damage whether you believe that or not. It affects the brain, learning and motor skills.

        1. It definitely needs further research involving the stronger strengths of cannabis (‘skunk’) that most use nowadays. I know far too many young adults who smoked ‘skunk’ in their teens who are depressed, unmotivated and worse, others who suffered such severe mental health issues that they took their own lives. These young people had good homes and parents and the common element was smoking ‘skunk’. My own loved one suffered with psychosis due to it, which continued use led to schizophrenia. I have met far too many young people under 25 in mental health units who are heavy cannabis (‘skunk’) users. When they are psychotic, they believe that cannabis (and nicotine) helps stop any voices or delusions they have, so keep smoking it – unfortunately, it just makes it worse after a short period of time.

          I cannot see how smoking stronger strengths such as ‘skunk’ whilst pregnant does not impact upon the developing brain of a baby, when recent research has shown that smoking it under the age of 20, whilst the brain is still developing, can result in developing psychosis.

          When I was young, smoking cannabis was seen as harmless and this was obviously due to the type of cannabis (resin type) that people mostly smoked. We need to re-educate our young people on the dangers of stronger strength cannabis on their mental health.

    3. Exactly, Im not bragging by any means but I smoked with my son and he’s always outshining the other students quiet and attentive. My sister smoked throughout her pregnancy with my nephew and he’s a chess champion and well behaved his school wanted to skip a grade but he didnt want to leave his friends. These studies are HIGHLY questionable when the side effects on a national website list the same as cocaine, and thats absurd.

      1. So what parent in their right mind would risk any Part of their child’s health just a smoke a joint? Is it really worth their IQ points, their attention span, their possible future doubled risk for drug addiction depression etc.?
        These studies have been done in a scientific manner. Open your eyes and realize that introducing any chemicals into your body isn’t natural nor normal.

        1. Thank God there is common sense in someone. Not just marijuana but DABs, 98 % oil of marijuana which is pretty bad. Our grandsons is in the hospital with claps lung and not eating because mom and dad both use DABs 5 of 9 months. I hate marijuana.

          1. shut up sandra there’s nothing wrong with weed just because you don’t like it doesn’t mean other people don’t benefit or need it your what’s wrong with the world and if you can’t mind your own business and deal with people’s medical and recreational needs then you need a life and a therapist

    4. Thank you! I was wondering the same thing. Half of those traits are practically passed down genetically. At least that’s my opinion throughout my family

  2. My Grandson has been diagnosed with ADHD. BUT I have watched him he seems to be autistic. Dr diagnosed in in like 10 minutes I have been studying his behavior for years.

  3. My daughter at the age of 10 was diagnosed by a doctor not a nurse with petit mal seizures. We knew there was something wrong since the age of 4 years but the mother who is a registered nurse insisted she had adhd. I thought my daughters behavior was a result of the mothers Marijuana use all through her pregnancy wich I never supported and was against. She said her doctor told her it would be easier on the child to continue useing while pregnant. My doctor told me he does not believe any doctor would say such a thing. I do not believe their are any benefits to useing Marijuana for the child and can’t say for sure it caused her problems but it definitely did not help.

  4. I adopted a girl from a cannabis mother. The list above of finding is her. She also has very low empathy . Highly manipulative. Balance issues .she flinches and jitters all time. Struggles with eating and low weight. Poor immunes system. Poor coping skill.

    1. Probably because she’s adopted. I grew up in the system. Don’t blame pot. It’s been a blessing in my life after I was forced to take meth in the system

      1. Parenting starts while the child is in the womb. So feeding a growing fetus marijuana is good parenting? Your opinion is flawed.

    2. My mother didn’t use marijuana when she was pregnant with me and I had all these same issues growing up. But I was also in an abused household. These problems sound completely normal for a child that is going through something. I wouldn’t be so quick to blame it on the mother and your bad parenting skills. I had a lot of terrible homes through the adoption agency and terrible parents with no patience. They think they want to travel child now they want a perfect little baby just like everyone else.

      1. Oh Weed Almighty. Bless my dear child that comes 2nd before you. May you make my child smarter and healthier than the mother that was clean and drug free. Ame? What was that word i was looking for?

    3. that’s not weed that sounds like bpd or some other behavioral disorder i suggest consulting a psychiatrist

  5. I’m a preschool Director/Teacher. I’ve seen first hand the effects that marijuana has on a childs ability to think.
    They just can’t grasp what they are being taught. It’s so sad. Their little brains just don’t work properly.
    If you’re a pregnant mom don’t smoke marijuana, or take cannabis. Choose your baby first.

      1. No they don’t. Speak for yourself. Thats quite a blanket statement, bulking “everyone” in together like that. I think that you’re defining disorders as “any medical conditions known to man” lols, and you’re wrong because a disorder is one specific category of a medical condition. You should know this stuff.

      1. if you are attached to cannabi you will defend it with all your might, if it affects your mood when you crave cannabi and after using it certainly it will affect a baby brain that is still developing, take easy with your baby

  6. I am a pretty avid pot smoker. I have had 2 kids now and I am 25. I did not start smoking until I was 18. It has actually helped me through my ADHD and depression and anxiety. I was pre-diagnosed with these disorders before I ever touched pot. My daughter is smart, she learns quick, can do different brain teasers and puzzles in record time. She is now 5. I have a boy who has recently turned 3 months. There is not a single thing wrong with him. He’s smart, since he was just over 1 month old he could hold his head up and himself up, he started rolling over at 2 months and tried pushing himself. He is healthy and happy. There is not enough research done yet to say that the effects of marijuana are going to cause problems. I mean nothing in life is entirely healthy but I’m pretty sure marijuana has killed less people than peanuts. So until I am given better research results I am a complete advocate for marijuana.

    1. I agree, I also have 2 children, one whom was just born and is only 7 days old and is VERY alert, she’s already trying to lift her head, she responds to noises by turning in the direction she heard the noise and I’ve never seen her jitter or jump in her sleep or anything they’re saying happens when they’re exposed to marijuana. Also I have a 22 month old who also was exposed to marijuana and my baby is already saying her ABC’s, she’s potty trained, and she loves for me to read to her, she’s very outgoing and just advanced overall for a one—almost two year old!

    2. Thanks for sharing I appreciate it I’m 35 weeks & can’t really stop because it is my medicine for my depression & anxiety

    3. >My daughter is smart, she learns quick, can do different brain teasers and puzzles in record time. She is now 5. I have a boy who has recently turned 3 months. There is not a single thing wrong with him. He’s smart…

      Sad they are “just smart”. They would have been brilliant with higher IQ’s if you didn’t smoke put during your pregnancy. Ever consider that?

      1. So Ken, please explain to me how being smart is not enough? And how do you know that if she didn’t smoke marijuana that her kids would be deemed “brilliant”? Hell, my mom never smoked with me and I can tell you that I am smart, but no where near brilliant.
        Here are some “smart” words that my mother did teach me, “if you have nothing nice to say don’t say anything at all.” You could’ve addressed your stance on the issue without bringing someone else down.

    4. Kudos to you for sharing, i totally agree. None of the studies so far inclide enough info about the patient;how they were raised or conditions previously diagnosed in family history

    5. Same. My 2 year old son is almost too smart actually, and this just isn’t his mother talking. I’m encircled with internationally known Montesorri administrators and school social workers, who have shared how impressed they are with how quick, coordinated, how they can see him problem solving when faced with a task. He was holding his head up in the hospital shortly after birth! Myself and his father are both educated and athletic so I’m sure his genetics haven’t hurt, I think my use of cannabis during pregnancy, to help with joint pain accelerated/enhanced his brain. He sings the ABCs, some letters are repeated-he’ll be two end of March, and counts while he’s on stairs “8, 9, 10” repeated. Hit hit every milestone early. . . I call Bullshit on this article.

      1. How much marijuana would you recommend a pregnant mother to take while carrying. 2 or 3 fatties a day?

    6. I agree with you. I smoked pot while I was pregnant to quell my anxiety and depression (prediagnosed & medicated before both pregnancies, stopped taking meds while pregnant). I only smoked my second pregnancy because I was so sick (I only gained 27 lbs) and all the research I found beforehand was nothing but positive, other than the people who just disagree with “drug use” or smoking while pregnant altogether. One of the things that’s stood out to me was the artistic ability that was assumed to have been raised in moms who smoke. The only reason that stands out to me now is because my son is 14 and has been making music since he was 8 & playing piano (Fur Elise from memory!) by 10. He creates YouTube intros for friends and all kinds of stuff. Highly intelligent, gets As & Bs, very socially active & healthy. My now 9 year old daughter is too very artistic. She likes to build things and engineer…. the 3D LEGO’s architectures are her preferred Christmas and birthday gifts. However, she was born with a heart murmur and hypo active thyroidism. The murmur went away naturally but she will have to take synthroid her whole life bc she basically doesn’t have a thyroid. My mother in law has the same issue, so I’m not sure where that would fall. She’s also an A-B student and has won 1 & 2nd place in her school district for art (mixed media & pastels) in the last 2 years. I say nothing is good in excess, but in moderation everything can be manageable. Just talk with your doctor and be honest. Also, if you’re aware of studies going on and you’re pregnant & smoke pot, help expand research if you’re comfortable with it. I wish I would have so the scary stories wouldn’t be the only stories out there.

    7. Thank you the first mother with real life experiences. My mother did not use marijuana when she was pregnant with me and I actually had all of these problems listed above. Trouble concentrating trouble thinking. However as an adult, I do use marijuana which helps me with my depression and my ADHD. There’s no conclusive evidence that marijuana affects your fetus.

    8. Was your babies tested for THC? My daughter just had her baby and they tested the baby and she came up positive…now my daughter is going thru all this crap! Can they take the baby from her because of this?

      1. No they can’t take the baby! They can only do a home study and CPS just doesn’t want any smoking around the baby which is perfectly understandable. Don’t let them intimidate you.

    9. I am with you Mama O smoke for 28 weeks pregnant with my son who is now 9 years old and he is a straight A student and was advanced as a baby he was walking at 8 months old. There needs to be more research done I’ve seen healthy moms who don’t smoke weed have the most problematic children and illnesses in their children than mothers who smoked weed. It is all a crock of crap. These kids with seizures are being given Marijuana to control their seizures so who is to really say it has that negative of an impact on a child’s brain?! If it wasn’t for weed I would have never been able to hold down food and stopped being nauseous all day long with having Hypermesis Gravidarum this pregnancy. I just quit at 31 weeks and I’m due in 9 days. My baby is perfectly healthy and is almost 8lbs! I’m not hearing any of the negativity.

    10. Exactly. There is not enough research that’s been done, so why take the risk? It’s selfish on your part to make the choice knowing there isn’t enough research to prove it’s okay or not okay to smoke weed while you are pregnant. You’re just going based on your bias in thinking smoking weed is absolutely fine. Wouldn’t you just want to be cautious and not take that risk IF there are adverse affects on your baby. Just so irresponsible that you made that choice for your children who are powerless and incapable of making that decision for themselves.

    11. The problem with this is there is data that it causes damage so why would you risk your baby’s health & brain development for your pleasure? Tell me. Do your research on this. Frequently used during pregnancy damages your babies brain and caused learning problems & more skill problems! Smoke at your own risk but not when you are pregnant! Period!!

    12. Thank you for sharing this. I took edibles moderately during my pregnancy and while breastfeeding to manage nausea and anxiety and my son is doing awesome. He’s attentive and musical and vocal. He’s 3 months and drs say he looks like 6 months. Women used to be given opioids and told to drink. We didn’t know about fetal alcohol syndrome until the 70s.. and many people grew up fine despite not having those facts. It’s individual.

  7. Why do I feel that these women are already a high risk group for these depression/anxiety issues – what was their use for cannabis? Was it to treat such problems or used recreationally? If it was used for mental issues, I’d say babies problems are hereditary rather than from exposure There really needs to be more studies done so people don’t take half information and run with it.

    1. Is called being dependant on weed and does not cure your anxiety but actually is the cause of it while you are off the herb. Your fooling yourself into believing weed is the cure for your problems

      1. Weed is not meant to be a cure. Is tylenol a cure for a fever or does it help the symptoms? Most people smoke weed to help them get through situations or problems they are having…not to cure them.

        1. Marajuana has been the only thing that has helped me with bipolar dissorder. After being on 10 different medications with verying side effects including suicidal tendancies, and marijuana has no side effects on me and is a lot cheeper than any synthetic medication I have taken.

      2. This is literally such an idiotic comment. There have been hundreds of studies from numerous universities that detail the benefits of ingesting different cannabinoids. So you’re just flat out wrong with that one. Second of all, you saying that is actually incredibly ableist! Claiming that people that use marijuana for the medicinal benefits are dependent on it is just messed up and completely untrue. You’re invalidating the treatment and disorders of millions of people all over the world. If not billions. Just say you’re like 65 and think Reagan was the best president and sit down.

        1. Actually i thought JFK was a great president. You seem quit defensive on this matter so near and dear to your heart. For some i suppose is a cure for mad cows disease.

  8. We have many studies but marijuana users will never believe them. We could have a thousand studies that say marijuana is harmful and one study saying it helps and that the they will run with.

    1. Please list one of those thousands of studies because based on my hundreds of hours of Google research I can find nothing that is conclusive. It all says it may affect your fetus. As of now there is not enough data. And there’s not enough negative data as well. A lot of information online is just opinionated BS. But I want to see the scientific studies with conclusive data of factual information. It doesn’t exist. They’re studying rats not humans. My friend is a heavy marijuana user and her child is on honor roll in a Tech High School. So I see no proof that it affected him negatively at all. He’s an athlete and he’s brilliant.

      1. Thank you for you using common sense. I am not being sarcastic. Nothing in this study made sense as any of the factors brought up are more likely a result of outside influences in raising the child rather than use of any kind of chemical. I have no scientific evidence however i have known many women who have smoked in the same house as their child or smoked while pregnant and by far those kids seem to be the most well rounded, practicle, and responsible kids as well as very intelligent. I agree these studies are not being done on people. Also notice how at the start of this article it says not many studies have been done.

      2. Why is your name meow? One thing is for sure this precious weed is far more precious to these mothers than their unborn baby. My precious.

  9. People with ADHD are more attracted to drug use. And considering the fact that ADHD is herditary, we can safely assume that the reason kids of Marijuana users have ADHD and similar “disorders” is purely hereditary.
    Meaning the main argument of this article lacks the understading of the diffrence between corolation and causality.

    (I apologize for mispells im not that used to typing in english. but this article was so painful I just had to reply)

  10. Hi there,
    Just came across this article and I must agree that it makes sense, all that you wrote in it about the dopamine reception specially.
    Marijuana use creates a havoc on the natural dopa receptors and it has been proven, especially when consumed frequently.
    I am glad that you are spreading this type of awareness. Our digital world and technologies can help us substitute Marijuana anytime, it’s over to people to realize it. There are many other natural remedies
    Cheers

  11. Ok personal experiences are not the same as a peer reviewed study. I hope everyone understands this. Not hating on how you feel but these are longitudinal studies. If you dont agree, either do your own research or accept that that may be the case. Marijuana may be good for some things but marijuana does indeed affect a developing brain, it does it to preteens who use it everyday so of course it would affect a brain that’s forming in the womb.

  12. Let’s all take the time to understand that Studies are done for a reason, mostly to gain a better understanding of the affects that substances may have on the body while being used. This does not mean that everyone will experience these affects. It is to educate on the risk involved, and possibility of these affects. It is then up to us as consumers, to determine if we are willing to take that chance. In this case, are we willing to take the chance of exposing the unborn fetus to this substance, after learning there may be a POSSIBILITY of a negative outcome for this child and their future? It all comes down to how much you’re willing to gamble, and how much risk your willing to take.

  13. My 3 month old grandson is precious but he is experiencing direct affects of his mother’s smoking in the same apartment where he sleeps. She puts a towel under the door but that does nothing for the vapors permeating the entire apartment. it’s in the carpet, in the walls, in everything that can hold a smell-fabric, clothing, etc. he can;t keep still most times but not as in baby motions– he is jerking and startled by magnitude of rapid motions. This calms down a great deal while he is at my house. It is abuse. plain and simple.

    1. Does he sleep alot my 3 month old grand daughter is in a home where they smoke I find she sleeps alot when I keep her she wakes more often to eat

    2. This is so sad and it is abuse. Toxins going into bloodstream with every breath . I see the easily startled ones, the shaking arms and hands. Pray that this all stops…

      1. Ummmm marajuana does not cause the shakes in babys. Thats crack, cocane, and even alocohol. To “od” on marajuan you would have to smoke over a lb of weed which is impossible btw. I am not saying ot is wise to smoke while pregnant but if your going to shoot up your kid with mercury, formaldehyde, aborted fetal tissue, and animal remains I cant imagine marajuana being much worse than that. Oh and floride in the water too. Just saying. There are many legal things that are much more harmful to your child that we considder to be normal and even healthy and no one bats an eye. I have known several women who had smoked while pregnants and their kids are bright and well behaved. Some have even skipped a grade.

    3. This is horrible and your grandchild should not have to suffer the constant exposure. However I do not believe cannabis use is completely abuse. I smoke in a safe environment away from my children and keep all of belongings completely out of reach. I never let my house smell of it or expose my children to it. I hope your daughter realizes her use is not safe for her child, but not everyone is like that and most are just trying to do what they can to have a stress free pregnancy.

  14. It is a great blog post.I am always read your blog helpful

    and informative tips. I like it thanks for sharing this

    information with us

  15. Vote is up for prop 207 today in Arizona (legalization of marijuana)
    With having frequented marijuana use as a juvenile, and my parents being busted for distribution, I of course lean to legalization.
    Although, being a nationalist (not white nationalist) I can distinguish a number of dynamics and parameters that marijuana has intermittently interceded, with the likes of this ;and microevolution in frequent users in general being the most resound… And with this and that, part of me wants to say no.

    With that, is there any studies into the correlations between propaganda and the premise to negative inert predispositions or positive inert predispositions in the parents, reflecting in their interaction with the children that might effect things such as dopamine levels, glutamate signaling, and synapse formation?

    I have read that growth can be severely stunted by stress and negative thinking. How does a mothers general attitude reflect in her speech pathology with her child, constantly thinking that he … could be potentially less intelligent due to the study?

  16. Thank you so much for posting this. This is very informative and worth reading. I would be glad to share this with my friends and family.

  17. Would you let your 5 year old smoke marijuana? The women claiming smoking marijuana has no effect on the fetus are in denial. What is their tolerance level? Not the same as an unborn fetus. Per pound what is the prescribed dosage a pregnant mother should take without causing harm to fetus?

  18. Excellent post. This is something that is not brought up enough. We always hear on marijuana and the developing brain on teens and youth. We NEVER hear any evidence based backed research on pregnancies. Loved this post.

  19. Could it be possible those behavioral and developmental issues were genetic? And is this study purely based on marijuana use or were these mother also partaking in tobacco, alcohol, or other drug usage? This study seems slightly vague and doesn’t give a lot of solid facts on the controlled variables that were in place.

    1. I am a concerned GG and I was just asking and got some pretty lax opinions.. if a parent really cares about their child or fetus they will do everything possible to make sure their child is healthy and normal.. Children are a gift and only loaned to us for short time.. Please make sure you do everything possible to make sure your child is protected from start to finish … or don’t have any.. Life is hard enough without disabilities and abuse..You see some that do fine but you don’t see the ones that don’t.. Try thinking about them 1st. And fore most..

  20. This study does seem slightly vague, but I can tell you in my experiences with my son and his older brother who is not mine. The mother smoked while both kids were in the womb as well as smoke around them as infants and toddlers, sometimes in enclosed areas. From what I have seen while in the womb didn’t seem to be such a big issue but once out of the womb she continued to smoke around them and that definitely had an impact on certain areas of their lives, including but not limited to behavioral problems, learning issues, and add/adhd. I don’t care who you are but you should definitely not expose your children to the side effects of Marijuana it is a psychosomatic drug that does have effects on the brain especially developing brains in young children. My sons brother has an extremely hard time with sleep, learning, memory and behaviors and I do believe it is due to this exact thing. No young child should have any of this forced upon them when they aren’t even old enough to make that decision for themselves. Your children should always come first before a joint or a dab. I used to smoke weed as well but but never condoned it while she was pregnant and I would get mad at her for doing it around them as infants/ toddlers and I feel my son and his brother are now paying the consequences of their mothers actions. Shortly after my son was born I stopped smoking because I wanted better for my son then how I grew up and how I watched his brother grow up. Children are pure and innocent and exposing them to this in my book is just bad parenting.

    1. Why don’t you all answer the question.
      The strains of cannabis are so different to many years ago.
      Anyone that smokes weed has an altered perception to reality.
      Good luck with research

  21. Hello, if the next father smoked for 1 year before conception canabis and different THC substances, the mother doesnt smoke at all ,which are the risks for baby? It can appear brain problems or something?
