Does marijuana cause schizophrenia?

[Jameerthefear]

Our teacher told us that. Looking for a concrete yes or no because I see some people say yes and some no.

[ballup]

Marijuana's effects differ between the person. I had one friend who, despite how many times he tried it, would always become paranoid.

[The_Yearning]

Experimentation goes a long way.

Screw what the text says and try it yourself.

Jammer pot is very dangerous, it can kill you, it can kill others around you without them having to smoke it!! A single marijuana cigarette can cause a perfectly normal young man with high intelligence to act in a way he otherwise wouldn't.. symptoms include but not limited to; agression, violence, extreme violence, sexual aggression, sexual violence, suicide, attempted suicide, and many more

please stick to legal substances such as Alcohol and or Tobacco as these are much safer and have proven to not have many health effects

There are also many productive and legal prescription pills that can help with most things pot advocates claim pot can help with, and the good thing about pills is that they are addictive so you'll never forget to take them and will always be healthy!!

No, but it does alter your brain chemistry and you should avoid it until you're at least 25 when your brain is fully developed...

Or you could be like a normal person and smoke/drink excessively in college and have the time of your life. :confusedshrug:

Cannabis is a drug and terrible for your body, specially if you are young.

I hate when people act like it's a great thing. I understand the arguments for legalization, but let's not act like it does not cause harm to a person's health.

This new study recent published by Harvard scholars says that even casual marijuana use can mess with your brain.

Everyone in this thread should just smoke a bowl and go out and enjoy life.

[russwest0]

You want a concrete answer? No, it doesn't.

Marijuana is like booze, you do it when chilling with your bros to have a good time. Just don't expect to start seeing funny colors or some shit like that. Main thing is you will get cotton mouth and laugh more at shit.

If you wanna trip balls I'd recommend DMT and LSD

[MavsSuperFan]

no, some people experience a little paranoia, but you would not develop schizophrenia

Edit: forgot the not

That's your experience. MJ in moderate to high doses gives me the shakes and makes me paranoid. I can be in a completely comfortable environment and it still happens.

So yea OP it certainly can. I would say I have some control issues though and it makes me feel out of control. Everybody is effected by substances differently. However you are effected is how you are effected.

[Smoke117]

Does Marijuana cause schizophrenia? Absolutely not. If you already have a predisposition towards schizophrenia can it make it worse? Yes. There is no scientific evidence that it can actually cause schizophrenia in someone with no history whether genetically or throughout their life for mental disorder, though.

[shlver]

Psychiatry assigns labels according to symptoms. "Schizophrenia" is a collection of symptoms that has many possible causes ie enlarged ventricles in the brain, viral damage to the brain, allergies, etc. Dopamine has been implicated to cause schizophrenic symptoms(dopamine hypothesis of schizophrenia, d2 target drug experiments(stimulants ie cocaine, amphetamines)) and as a result, antipsychotic medications have been formulated to specifically inhibit dopamine receptor activity. Now does marijuana directly cause schizophrenia because of possible increased dopamine activity or any implicated neurotransmitter? Probably not. Schizophrenia has been shown by multiple studies to have a strong genetic component as familial history of the disease greatly increases the risk of exhibiting symptoms. The most likely conclusion would be marijuana use triggers or exacerbates an underlying genetic predisposition to schizophrenia.

[Dresta]

Supposedly people who smoke pot are many many more times more likely to get schizophrenia but supposedly schizophrenia rates have not gone up with a rise in marijuana usage. So really know one knows the connection but I feel pretty confident these two things have something to do with it
1-schizophrenia is heavily linked with problems during birth (usually deprived oxygen stuff) and other stressful/damaging events during early brain development. As medicine improves thats not really a common occurence so it could easily offset the marijuana usage growth
2-People just under reported usage in the past. It has a stigma attached with older generations but much less so now.
TL; DR Nobody is sure but there is certainly some sort of connection.
Source:I used to be a psych major.
Schizophrenics consume most drugs at higher levels. Drug use can often be self-medication during the onset of symptoms.

Lol that's a short term study, with a small sample size, and they're not accounting for confounding factors and corollaries of children in their teens who on average smoke 6 joints a week; i.e. home life, diet, alcohol abuse, exercise, etc.

[CeltsGarlic]

instant schizophrenia.

[boozehound]

definitely doesnt "cause" it. Can it cause someone who is schizophrenic to have an episode? Perhaps. But it doesnt cause it.


This is why young people dont believe anything their teachers say. The teachers say a bunch of unsubstantiated nonsense that is easily refutable in order to scare kids straight.


I had a middleschool teacher tell us about a girl who got pregnant by letting a dude *** on her bush. Either she was dumb enough to believe a lying teenager who didnt want to admit to penetration or she was purposefully lying to us to scare us away from sex.

[Rameek]

I know a few people that some serious psychosis occurred after smoking. Cause and effect though is tough to prove.

[-p.tiddy-]

just reading these posts...if it is true that pot can cause someone with "dormant" schizophrenia become "un-dormant"...then I would say the answer is "YES"...adding a "can" or "may" though, "yes" marijuana "can" cause schizophrenia

[DukeDelonte13]

No. Marijuana absolutely does not cause schizophrenia.

As another poster has suggested, there have been studies that casually link marijuana use with potentially "flipping the switch" so to speak, but people who are predisposed to bipolar type I and schizophrenia will ultimately break out and enter into a manic state regardless of MJ use.

The studies aren't so great because they fail to take into account the the vast majority of the time people who enter manic states that will later be diagnosed as schizophrenia or bp type I, are all young, (typically between 17 and 27 or so) and more young people than not have smoked weed. Also It's really unknown and kind of impossible at this point to say whether or not one can be schizophrenic or bipolar and never show any symptoms of the disorder.

One can be predisposed genetically, but nobody is ever going to have an early conclusive diagnoses of those disorders.

[oarabbus]

Yes, it does. We know this for a fact. It has been shown to us by god. Each 25th blunt creates a new voice in our head.

[secund2nun]

No it doesn't. Only people who have an agenda like the prison system pump out this false BS or people who have been brainwashed by the anti-weed agenda like your teacher.

The other problem is, like with all outlawed substances, a lot of the longterm effects -- both positive and negative -- are really not known, because the century-long prohibition meant serious scientific studies were not possible.

It's the same problem with anabolic steroids and their real (not perceived) effects. There are a lot of people who believe, if taken in moderation, steroids pose no health risks whatsoever. Meanwhile, there is all of these links that people just seem to generally accept, like steroids causing cancer, heart problems, etc.

Fact is, we don't have any hard, scientific data proving or disproving these notions, because scientific lab work is subject to prohibition the same way the general public is. A lot of what you've heard about anabolic steroids is based on weak correlation and flat-out propaganda.


The more states that legalize marijuana, the more we're going to eventually learn about what it does and doesn't do, both positively and negatively.

[-p.tiddy-]

*on a some what related note

A couple weeks ago I read an article on legal sales in Colorado only being about half of what they expected and not producing the kind of tax revenue that everyone expected, and also supposedly the black market for pot in Colorado didn't go anywhere at all...it's still there, possibly thriving better than ever due to legality.

[Dbrog]

I'm a licensed professional counselor and work with people diagnosed with schizophrenia everyday. Every single person I have met with this disorder has either had significant abuse issues in their childhood or got their first symptoms after first using drugs (not alcohol). I've heard from multiple clients of mine as well as read research on this which suggests drugs such as marijuana, ecstasy and meth (and likely others) will trigger the schizophrenia gene (which is biological). If you want to know what it's like to have schizophrenia, go ahead and try a hallucinogenic...just know you are putting yourself at risk of other health and potentially life-altering concerns. Majority of my clients had theirs triggered by marijuana...just sayin'

TL;DR: Marijuana can trigger schizophrenia gene that might otherwise be dormant.

Sounds like more of a chicken/egg scenario than concrete data. I'm guessing that the onset of schizophrenia tends to coincide with the years people are most likely to be experimenting with drugs for the first time?

This is why we need long and short-term studies of the drug, to separate fact from fiction. Strict prohibition doesn't allow for that.

Well the data will certainly all be correlational until they really can isolate the schizophrenia gene and get better and bio-science. Still though, from my experience, I've met enough people to come to the conclusion that drugs can trigger it (not all of mine have been young when they had their first symptoms). On the subject of prohibition, I'm torn. I'm all for people making their own decisions but I don't want it to be ok for people to take substances that can destroy their lives.

[oarabbus]

The data suggests that marijuana use can exacerbate schizophrenic symptoms or result in a quicker onset in those susceptible to schizophrenia. In addition, this only occurs in a small subset of schizophrenia-prone users.

Marijuana does not trigger or cause schizophrenia in normal individuals as far as we know.

All the sh1t about it killing ambition, motivation, and causing laziness is true, though. I know some 4.0-type stoners in college who did everything high and were very successful at what they did, but I could count those people on one hand. They are the exception to the rule and smoking a bit of weed is harmless but it did negatively impact the lives of most daily smokers I've known.

Cannabis smoke contains thousands of organic and inorganic chemicals, including many of the same carcinogens as tobacco smoke.[25] A 2012 literature review by the British Lung Foundation suggested that the risk of developing lung cancer is nearly 20 times higher from smoking typical cannabis cigarettes than from smoking tobacco cigarettes, due to deeper, longer inhalation and the lack of filters.[26] They identified cannabis smoke as a carcinogen and also said awareness of the danger was low compared with the high awareness of the dangers of smoking tobacco particularly among younger users. They said there was an increased risk from each cannabis cigarette due to drawing in large puffs of smoke and holding them.[26]

Tennant & Groesbeck (1972) identified 115 cases of schizophrenic reaction among the 720 regular users of cannabis; however, all but three had used cannabis with other drugs or alcohol. Thacore & Shukla (1976) compared 25 individuals with a putative diagnosis of ‘cannabis psychosis of the paranoid type’ with controls diagnosed with paranoid schizophrenia. Patients with cannabis psychosis showed more bizarre behaviour, violence, panicky affect, more insight and less evidence of thought disorder. They also showed a rapid response to neuroleptics with complete recovery. More robust in methodology is the work of Rottanburg et al (1982) in which 20 patients with psychosis and with high urinary cannabinoids were compared with 20 matched cannabis-free controls. Mental state was assessed using the Present State Examination (PSE) (Wing et al, 1974). The cannabis-positive patients had more symptoms of hypomania and agitation, less auditory hallucinations, flattening of affect, incoherent speech and hysteria than controls. Clouding of consciousness was absent in most cannabis patients. They also showed marked improvements in symptoms within a week, while the controls remained unwell despite receiving comparable antipsychotic drugs. The authors conclude that a high intake of cannabis may be related to a rapidly resolving psychosis with marked hypomanic features. However, 16 cannabis-positive psychotic patients left the study prematurely, which may bias the findings on the 20 who remained. Rapid resolution of symptoms is also reported by Carney et al (1984), who identified nine patients with cannabis-related psychotic episodes. Their differing symptomatology was described as ‘schizophreniform, manic, delusional psychosis and confusion’.

from a personal experience, I used to get paranoid as hell when I had zero tolerance. It will go down with long term use and in due time you get used to it. Paranoia is common among younger users, you feel panicky and you feel as you have no control over your actions and you may feel really uncomfortable in any environment. Worst case scenario would be drinking and smoking at the same time, which can lead to a lot of bad effects. I've experienced memory loss multiple times, even when I've only drank like 3-4 beers.

People say it's safe and all, and in reality it is, but if you have previous mental issues related to schizophrenia, it might not be the best idea in the world to abuse the substance, especially if you have anxiety.
