We need tougher deterrents. For example, the punishment for failing drug tests needs to be more severe. Instead of six months or no punishment (Peterson), there needs to be, for example, a 1.5 year minimum suspension for the first offense and 3 years for next offense. If the fighter is caught prior to a fight, and the promoter elects to go through with the fight, a large percentage of the fighter's purse needs to be forfeited, say 65% or something.
