And the next time a celebrity makes it seem like legalizing marijuana is the be all and end all of drug law reform, slap him in the face. (Metaphorically, unless you want to get your time on TMZ). Legalizing pot is the least of it. Getting politicians to understand how their actions contributed to the problem is a lot harder and requires more effort, but will ultimately pay off. If mandatory minimum sentences are reduced, for example, judges will be in a much better position to consider family structure when pronouncing a sentence. This local discretion could mean the difference between an intact family and a broken one.
Beyond that, since the United States isn’t about to legalize or regulate the illegal narcotics markets, the best thing a president can do may be what Obama winds up doing if he gets re-elected: using the bully pulpit to draw attention to the issue.
