"Although Nixon declared the War on Drugs in 1971, the policies that his administration implemented as part of the Comprehensive Drug Abuse Prevention and Control Act of 1970 were a continuation of drug prohibition policies in the U.S., which started in 1914. Less well-known today is that the Nixon Administration also repealed the federal 2–10-year mandatory minimum sentences for possession of marijuana and started federal demand reduction programs and drug-treatment programs. Robert DuPont, the "Drug czar" in the Nixon Administration, stated it would be more accurate to say that Nixon ended, rather than launched, the "war on drugs". DuPont also argued that it was the proponents of drug legalization that popularized the term "war on drugs"."
I can remember creating in 3rd grade in 1969-70 in class (along with everyone else) a workbook detailing all the common illegal drugs of the time, names, effects, and why they were bad for you, etc.
And as you probably know it continues to this day, the Obama Administration has been a terrible disappointment to those seeking decreased restrictions on marijuana (harsher than Bush? I forget). This has long been a Progressive cause (remember Prohibition?), and most don't know or remember that Nixon was a Progressive domestically, a long Republican tradition. EPA, OHSA, there's a whole list of things like that that Nixon signing into law and supported.
