Just the fact this opinion references Ronald Reagan's approach to drug policy invalidates pretty much the entire argument.  The Reagan's drug policy's have caused irreparable harm for decades that we are just now beginning to right.  It's understandable that law enforcement has this limited view point sometimes as they see mostly the negative outcomes on a daily basis.  Perhaps they should listen to doctors and scientists on this one though.  Its clear that cannabis is safer than most pharmaceuticals and definitely safer than alcohol and nicotine so let adults have their choice.
