Legalization of marijuana within the next 30 years is inevitable for most states. But legalization of heroin, crack, cocaine, meth? That's really a pipe dream.

Legalization of marijuana within the next 30 years is inevitable for most states. But legalization of heroin, crack, cocaine, meth? That's really a pipe dream. It might happen some day, but that'd be more on the range of 70-100 years if I were to guess, and perhaps a lot longer. Marijuana is a significant portion of sales on all of the dark markets, but other more addictive narcotics still constitute the majority compared to marijuana.
