And MARIJUANA is the biggest cash crop!
Imagine that!
Other than drug offenses, there is no correlation between marijuana use and crime. Needless waste of tax dollars. Marijuana is the largest cash crop in many states...but this doesn't affect the crime rate (except for drug-related offenses). It is not the largest cash crop in many liberal bastions...places with soaring crime rates (Michigan, D.C., etc.).
Before I get flamed as some type of libertarian junkie, (1) I have tried marijuana many years ago about five times in the aggregate, and (2) I don't use it now. Suggest you try it once before claiming it leads to Reefer Madness and the fall of Western Civilization.
