Only difference between NRL and AFL is the AFL are much better at brand protection, also Sydney journos are not afraid to muckrake NRL players and clubs. AFL seems to be able to stop this from happening most of the time.
Cannabis, coke, heroin and ecstasy should be legalised. Not sure about speed and no to meth. That said, OxyContin is a bigger problem than all of those, and most of those preaching zero tolerance in society are probably prescription pill poppers.
I agree with Dane Swan too on testing everyone in the AFL industry, not just players.
