I agree, it's both, especially considering that most drugs (not all), are derived from plants.
u r right except the other (herbs/drugs) r processed by man before consumtpion. Pot need no help from man to do its job, except for a lighter. Lol. I just recently quit smokin for a job. Pot is awesome. It should be legalized for people of 18 or older, taxed, and sold at your nearest convenience store. Just my opinion.
