Don't use stats on illegal things to prove anything. If anyone asked me about my drug consmuption i'd never tell them. I'd doubt others would either. Unreliable figures at best.
So long as i harm no-one if and when i take drugs, then the state has absolutely fuck all right to tell me i can't or i will be imprisoned. Denying me my freedom to smoke weed or go on a trip, and by locking me up is a massive crime perpetrated by other humans on me.
They have no right to stop me doing what i want, and in fact for 25 adult years i've happily not given them that right. They can go fuck off. My life.
Incidentally coke was never a drug choice of mine. But if others wish to take it, even to kill themselves, then the world will continue to spin on its axis and light will follow dark will follow light. Nothing will change. One less person, one more fucked up person, so what. Just coz they can't handle it why should others, the vast majority, be denied their pleasures?
