858,408 Pot Arrests

Jacob Sullum passes along the latest numbers:

As I've noted before, there is no obvious relationship between marijuana arrests and marijuana use. Although arrests have more than doubled since the early 1990s, the number of pot smokers was no lower in 2008 than it was in 1990 and perhaps somewhat higher, even allowing for methodological changes that seem to have boosted self-reported drug use after 2001.
