conquerclubs drugs test

i´m worst at chess, pool and can´t do anything phyical when i´m stoned but seem to play risk better, why? anyone else like this? i used to be between 2000-2200 when i was smoking but dropped to 1700ish when i stopped. down to 1600 now becuase of several deadbeats, left the site and i´m now traveling but played a proper game the other night in a hostal which got me wanting to come back here, stoned out off my head everything seemed so clear and i kicked ass.
