substance that tampers with brain chemistry might cause psychosis in some people.

We should imprison people for possessing substances that MIGHT adversely affect SOME people?

Try that with Plutonium, Anthrax or Sarin and let me know how that works out.

You must be high now. I've previously listed half a dozen or more psychotic killers who smoke(d) weed.

If psychotic killers smoke pot, they are within the Venn diagram of pot smokers, therefore some pot smokers are psychotic killers. As a matter of fact, near as I can tell, most psychotic killers smoke pot, if not all of them.
