As their name implies, the PDFA support a historically unprecedented goal, the "drug-free society." This qualifies them as loonies. The fact that their ads have no effect whatsoever leads them to ask for more money to put out more of the same ads. This is known as insanity.
The PDFA, a part of the Church of Voodoo Pharmacology, is a subset of the philosophical movement douchebaggery.
In the tradition of bigotry, the PDFA for many years were obvious hypocrites, accepting large sums money from alcohol, tobacco and pharmaceutical companies (presumably in the interests of reducing the competition in the market for mind-altering substances).
Stoner: OMG man this shit is fucking hilarious! (*takes hits from the bong*) They should put this stuff on DVD!
-Ashley: I had a great time tonight too!
-Andrew: You make me so happy.
-Ashley: I can't stop smiling because of you. :):)
-Katie: Stop with the PDFA or I'm going to vomit ... or hide you on my mini-feed.
