We've all seen the image of holding on to a hand of sand, the harder you squeeze the more falls out.
The same thing applies to the modern drug problem. The harder we squeeze on to sobriety, crinminilisation etc., the faster the problem jumps out of control.
The big problem is PROHIBITION. I.e. thinking we have the right to tell someone what he may or may not ingest. This is what CREATED crack and meth and heroine.
Presure on a substance increases the price, soon people need some high but can't afford that one anymore, so what is a good businessman to do? You guessed it, come up with something not illegal yet, cheaper to manufacture and just as addicting. I've had two serious addictions in my time on earth, one was smokeing mandrax (basicaly 'luuds with something extra added), and the other was crack. Man did those mess me up, and it took 10 years+, to start makeing a dent in the chaos that are concomitant with true enslaveing addiction. I thank psycedelics for helping me make the peace I had to with the world. The thought of takeing something lke crack or meth today, makes me feel sick to my stomach. And I realy fear for those who get caught on this path. At the same time I do not berate them as bad people. We are what we eat, and if enough people tell them they are bad, they'll quickly figure out, they may as well be bad.
