The sometimes-chaotic medical marijuana situation in California has spurred a fair amount of sensationalized and unbalanced press coverage, even in the esteemed New Yorker. Yes, there have been some problems and some misuse of the law, but an editorial in today's L.A. Times hits the nail on the head as to the real source of the problems:
Most of the negative consequences [of Proposition 215] can be attributed to the gap between state and federal marijuana laws. The fact that even sellers considered legitimate by the state can be prosecuted and ruined by federal agents encourages black-market dealers, who endanger their communities by ignoring fire codes, selling to healthy minors and fighting turf wars with other dealers. ... [T]he only long-term solution is for the feds to stop the medical marijuana raids and leave California law enforcement to California officers.
Precisely.
