The professional players' unions are getting upset about WADA's proposed long bans for recreational drug use. They (WADA) have also, not fully reported there, increased many thresholds of recreational drug use to completely eliminate false positives from, say smoke inhaled from third party's spliff.
I don't get it. Why would professional athletes have a problem with drug bans? If players want to run the risk of taking recreational drugs, which is still a criminal offence in most countries, then they can't complain about getting a ban for it. One player given a 4 year ban for doing cocaine would certainly be a useful deterrent for all bar the most terminally stupid of players.
