There is more going on here than meets the eye, and this is not just some crazy conspiracy talk. The Leftists are all about promiscuity, drug use, and mind numbing music; aka "sex, drugs, and rock n' roll". We now have a president that was so steeped in that culture, he makes Bill Clinton look like a conservative.
There are two things going on here: First, this Obama regime is dedicated to lowering social standards. I wouldn't say that social standards are particularly high today, but we are still not at the point where even most progressives would be fine living in a third world, classless, jungle mentality. The proliferation of drug use will help acclimate people to that sort of low-life social scenario.
Second, as in Brave New World, the use of certain drugs will be encouraged because it will allow people to feel artificially happy. The quote from the book as I recall was "A gram is better than a damn." Obama would love us to all become mindless automatauns, who love their president as the Soviets loved Stalin.
This "drug minister", whoever he is, has said he doesn't support legalization? Just watch. I will make a prediction that before the end of Obama's first term there will be a bill advocating for drug legalization.
