Marijuana and Psychosis: Correlation or Causation?

Please visit this article's new home at AriArmstrong.com. Thank you!


  1. Have to just love those "ever" questions...
    I have a friend that was involved in a rather difficult divorce, and during it all she accused him of sexually abusing their children, as well as her. Well, he ended up having to go through a screening process via court order. Virtually all of the questions he had to respond to were presented in the "ever" format. The results were being used against him, until the Judge asked him if he had ever acted out any of the things that he was being accused of. Well, he said no, but the tests had said "ever" as in thought about. Since he was a Paramedic, he had been taught about them, and so had thought about them. Go figure!

  2. Marijuana is most certainly NOT a hallucinogenic drug. It may alter your senses/perceptions (e.g. music may sound different, food may taste different, sex may feel different while under the influence -- and many users will claim that these sensory changes are an improvement) but it will absolutely not cause you to see, hear, or feel things that don't actually exist in reality -- cannabis is just not capable of producing these kinds of effects.

  3. Note to "Doctor Drew:" Next time try including some sort of plausible citation. A simple internet search reveals tons of sources claiming that marijuana is hallucinogenic.

  4. Ari,
    Citation is not necessary. Sometimes doing a "simple internet search" will reveal all sorts non-sense, such as your claim that cannabis is hallucinogenic. Google is not the Gospel. If you yourself have experience with cannabis (which seems unlikely considering your claim) then you'd know first-hand that it is not a hallucinogen. Of course if you're lacking in personal experience, rather than taking your talking points from drug prohibition dinosaurs, you can ask folks who actually use cannabis (I know, radical concept here) what they experience when under the influence -- shouldn't be hard to find a few, they're estimated to be about 10% of the US population, give or take. 1%-2% are daily users, the so-called "wake-n-bake" variety.
    Do you really believe that 2% of the US population is walking around every day hallucinating from sun up to sun down? This should immediately strike you as being absurd! I believe it is estimated that in Colorado by the end of 2010 there will be 100,000 patients on the medical marijuana registry -- about 60,000 currently on the registry or awaiting the state to process their application. So 60,000 people in Colorado right now experiencing hallucinations... really? Your claim is just non-sense -- and you want to stand by and defend this naiveté on the basis that an internet search tells you so? It's no wonder we've been flushing our tax dollars down the toilet for 70+ years fighting a never ending war on drugs. God help us all. Nobody under normal circumstances is hallucinating from cannabis. Nobody.

  5. Drew, your comments are off base, and I'm not going to publish any additional unsubstantiated comments from you.

    First, I have in fact smoked marijuana, and I have in fact experienced a (very minor) hallucination after doing so. (This was many years ago.)

    Second, nobody has claimed that marijuana causes severe hallucinations "from sun up to sun down." You're attacking a straw man.

    Third, nobody has claimed that most or even many marijuana users suffer hallucinations. Indeed, the very study I review claims that only a minority of marijuana users experienced a hallucination, and in any given case that may or may not have had anything to do with the marijuana use. (A smaller minority of those who didn't use marijuana also experienced a hallucination.) You are again attacking a straw man.

    If you wish to submit additional comments, please include some sort of plausible citation, and please refrain from Making Stuff Up about what I've written. I don't have time for nonsense.
