70s America was not a good time for far more than the drug culture. Rampant inflation, recession, vietnam, iran hostage crisis, etc.
Also as was noted, more people have died from drug usage since the 70s than in the 70s and drug use has gone up in the 90s.
Whew that is convuluded. Anyway drug usage is way down from it's peak in the late 70's and the uptick in the 90's can be attributed to the cultural pollution of the well known 60's radicals the Clintons, IMO.
And don't give the line of bull that Clinton was a drug warrior. I know you will post article after article saying that he was, but when has it been proven that the Clinton's ever tell the truth.
