I am convinced that there are genuine and valid levels of perception available with cannabis (and probably with other drugs) which are, through the defects of our society and our educational system, un-available to us without such drugs.

I've been smoking marijuana for 44 years now, and ... I think it's a tremendous blessing.

Marijuana is one of the least toxic substances in the whole pharmacopoeia

I have come to doubt whether the FDA rules should apply to cannabis. There is no question about its safety. It is one of humanity's oldest medicines, used for thousands of years by millions of people with very little evidence of significant toxic effects. More is known about its adverse effects than about those of most prescription drugs.

Cannabis is remarkably safe. Although not harmless, it is surely less toxic than most of the conventional medicines it could replace if it were legally available. Despite its use by millions of people over thousands of years, cannabis has never caused an overdose death.

I began to study marijuana in 1967... I had not yet learned that there is something very special about illicit drugs. If they don't always make the drug user behave irrationally, they certainly cause many non-users to behave that way.
