Does Michael Phelps effectively debunk all anti-marijuana propaganda?

[John Dibble]

Answering the question, no. Anecdotes can only refute propaganda that are absolutist, like saying "all people who smoke pot are losers who won't amount to anything". You should know this by now, BRTD. I don't think all anti-pot propaganda is quite to that point, so you'd need more data to refute the non-absolute ones.
