I hope those who oppose legalisation fully understand the arguments presented here and change your opinion from an irrational one to a rational one.

One thing, Andre: you tend to use decriminalising and legalising drugs interchangeably. They are not the same thing. When you decriminalise a drug, it's still an offence and against the law; it's just not a criminal offence.

And I wouldn't call current illegal use of marijuana a crime. You can't commit a crime against yourself (suicide is now legal). Refer to it as an illegal act.
