Ännu en studie som jämför cannabis med alkohol och tobak

The Beckley Foundation, a charity which numbers senior British and other academics among its advisors, said banning cannabis has no impact on supply and turns users into criminals.

"Although cannabis can have a negative impact on health, including mental health, in terms of relative harms it is considerably less harmful than alcohol or tobacco," says the report by the Foundation's Global Cannabis Commission.
