I can't be bothered to sign up to that site but this is what i would've posted:

It is physically impossible to overdose from smoking cannabis therefore it makes it SAFER then alcohol and tobacco. Those LEGAL drugs KILL hundreds of thousands of people a year, that is a FACT. I wish freedom to all the non violent cannabis users who are being imprisoned for executing their free will by consuming a plant which causes no harm and or suffering to anyone. LEGALIZE!
