From this article :

Marijuana has been used for over 5,000 years.
No one has ever overdosed on marijuana.
Aspirin has been used for 108 years.
Approximately 500 people die every year by taking aspirin

see? even suits smoke it.

Ah, fond memories of my weed-smoking days: joints, bongs, subs, cookies even. And now everything is justified – it was a terribly painful period of my life (uni studies), and I needed the painkiller.
