Weeds likes marijuana or hemps do not improve a players performance unlike nadrolone or creatinine which is known to build muscles and hence associations or boards should treat it as a diciplinary issue rather than a crime. It is something like drinking alchohol. But we don't get drunk and go to office, similary if a player is not on drugs while playing, there should not be any issue. Recreational drugs are an individual choice and countries like Netherlands has legalized it. It is pathetic people associate it with shame when our country has a rich history and folklore associated with bhang. Half the country goes mad in Shivratri.
