Cannabis will never be legalised IMHO.

We live in a society where you'll constantly need to function in a constructive way and need to be productive. It seems drugs take the blame when individuals don't comply to this. We have 2 legal drugs in our society, and every possible effort has been done to restrict both and, over time, make them disappear or illegal. I don't think we'll see the addition of a 3th legal substance any time soon. However pharmaceutical companies are busy developing all kind of medication for us to cope with the stress, No probs there.
