Obama: Romney Can't Say 'Everything I've Said For The Last 6 Months, I Didn't Mean'

He also said that some of those medical weed growers were selling weed to non-medical weed users

==========================

As are other schedule III drugs (sold illicitly, for non-medical use), but you don't see Obama making them schedule I.  

Obama based his flip-flopping on his campaign pledge on a president's inability to "nullify congressional law".  

The fact is that the law grants the executive branch the power to unilaterally change the legal status of particular drugs.  Obama has the legal power to change marijuana's classification from schedule I (which means it has no accepted medical use) to schedule III (which is what synthetic THC, the active psychotropic agent in marijuana, is in).

FWIW, I don't partake, but others who do can't "get their weed", as you put it, without the risk of running afoul of the law and resulting in everything from incarceration to fines, all costly.  The cost to me as a citizen (diverted law enforcement from real crimes, violent and other, court resourses, prison costs) is huge.
