This sort of debate (good rugs vs. bad) will only become more complex as we discover and build new drugs. What is now an illicit drug (cocaine, meth, heroin etc.) will look downright silly compared to the new custom tailored get-high drugs that come out of the drug company labs.

All I can say to people who are on both sides of this fight now is to "enjoy it while it lasts". The lines are only now becoming slightly blurred, in 20 years we'll look back on these times with great fondness. When we worried about blunt-instrument fun drugs and could tell the difference between a "steroid user" and a gifted athlete.
