It is my understanding that we cannot be fighting a war on things, whether they be drugs or guns, but on behaviors. In this case, it is drug abuse.

And in the scope of drug abuse, including alcohol and prescription drug abuse, does the cost of attempting to enforce and maintain a prohibition on marijuana have a proportional impact on that problem as a whole?
