this is an article i downloaded ages ago, and have lost the link. it is a *very* long read (125kb), but also *very* insightfull and well documented.
it explains a lot, amongst them why cannabis was banned, and some not commonly known links between major US industrialists, government (well, republicans really) and the german nazi party that continue up to this day.
due to its size i have broken it up into several chapters.
if you manage to read through it all, you'll get a little wizer
