Cannabis use leads to psychosis

[SamIam]

LONDON (Reuters) - Young people who smoke cannabis or marijuana for six years or more are twice as likely to have psychotic episodes, hallucinations or delusions than people who have never used the drug, scientists said on Monday.

The findings adds weight to previous research which linked psychosis with the drug -- particularly in its most potent form as "skunk" -- and will feed the debate about the level of controls over its use.

I guess this will add more fuel to the fire in the debate to legalize marijuana. I never heard of skunk before, but then I am not a smoker.
