Couldn't agree more mate. Thought I was crazy reading some replies. Personally, I think it's bad enough we have one mind-altering substance (alcohol) be so readily available to so many irresponsible people. So much violence comes through alcohol use but combine that with drugs and you just get fucking idiots everywhere.
Not to mention how cripplingly addictive class A drugs can be compared to alcohol. Legalisation provides a strong psychological suggestion that taking drugs is perfectly fine which would encourage much more of the populace to experiment. Do we really need a whole new demographic of people addicted to a substance that completely takes over their lives?
I can't believe we're considering it at all. Much more worthwhile to strive to become a society that actually solves the issues leading people down a path where they feel the need to take mind-bending chemicals to help give their lives meaning or escape reality.
