Why is marijuana legal?

In the 1930s, Harry J. Anslinger, America's first "drug czar," perpetrated one of the most enormous, most egregious deceptions imaginable, and its results and its lies are still with us today. Many people today believe that marijuana is a dangerous, addictive drug, only because back in 1936, Anslinger began one of the world's greatest public relations campaigns to demonize a plant that is actually less harmful to humans than alcohol or tobacco according to all research. And despite decades of legitimate scientific proof to the contrary, most people still believe the lies Anslinger created seventy years ago.
