What is the best drug for actually improved gameplay when you play Quake?

i find that when i played quake blunted =]<o

that i gain a deeper understandings of theory and complex ideas of the deathmatch within the game and i hit like a motherfucker with my rockets and i get accused of being a sneaky fucker aimbot with my 80% lg and then when i came off the ganja i suck again =[

so i roll up another spliff and *raymundo* i am pro again =p

i have used cocaine but only @ lan and i just found it made me aggresive irl and punch people in the face to my prison sentences
