Prepare for the shitstorm from local jeweed enjoyers.

It seems that negative effects are obvious to anyone but the users. I have witnesses people close to me quit smoking and reverting to a normal state gradually after about 3 - 6 months, so I'd say negative effects are not permeant.

Shit, that doesn't even address the decreased blood flow to the hippocampus while is a known condition for alzheimer's ~ so you've That to look forward to as well.

Here let me show you low IQ division shills how stupid you are.

There are 1000s of studies trying to figure out if this relationship is causal or due to some kind of confounding.

But zero proof after 1000s of studies? ...the same thing over and over again expecting different results...

extremely expensive — lifetime cost of about 1M in an Australian study — to society because schizophrenics need treatment, are very violent, and not very good on the job market.

This is nonsense. Literally all you have to do is STOP FUCKING SUBSIDIZING IT. The risk factors for schizophrenia are substantially heritable, and sometimes triggered by cannabis use. Much the way that the risk factors for alcoholism are heritable, and pounding MD 20/20 at 16 is likely to trigger it.

You know how to solve this for free? Stop subsidizing it and it'll disappear in a generation or two. Hallucinating potheads screaming at the sky lords dont reproduce. Or if they somehow do, they cant support a family and the problem goes away.

Schizophrenia is a vitamin deficiency.
