Here's to hoping people realize and deal with the
real gateway drug: Alcohol, that great destroyer of worlds, marriages, cultures, physical health and particularly the brain, time (hangovers, boredom), coping strategies (emotional pain), real pain (coping strategies), poor decision making (you know it), and so on. Start here, and come into it with a few entrenched problems, and sure enough you'll find yourself elsewhere should time and circumstance align.
To all the magical, healing drugs that are currenly illegal: may you one day be free. http://www.economist.com/blogs/dailychart/2010/11/drugs_caus...
