I thought we were past this kind of nonsense

Alright, so to sum up what they are saying, pot users are anywhere from 50% to 200% more likely to get psychosis than non pot users. They can't say that this is BECAUSE of the pot, but they can show that pot users are more likely to get psychosis.

They can't prove that there isn't something in effect that increases the chances of both pot use and psychosis, either. Maybe there's a disorder that increases your chances for both drug abuse and psychosis.

Also, the average chance of getting psychosis is about .5%, if you increase that by 50%-200%, you get a .75%-1% chance of psychosis. That's an increase of .25%-.5%. That's almost negligible.

They're retarded.

Don't you find it amazing that all they said was pot use MIGHT increase your chances of psychosis to .75%-1%, but they don't know for sure, and they made it sound so scary like pot will kill you. Do you know how many people are probably buying into their bullshit right now? It's sickening.
