I used to play smoking weed every day, but right now, i have more than 2 months without weed (or any non-prescribed drug, even alcohol).
I feel this time was more productive in general, specially studying and applying strategies in poker, but i will smoke weed in few weeks again (daily) becouse it doesnt is a problem for me in my game and work.
I have my own plants and im awaiting they to be ready, thats why im not doing any drug (i was using amphetamines and benzodiacepines, thats another history, and will mess with your game and life for sure, if you dont have medical prescription, i have dexamph, clonazepam, paroxetine and micro dose of quetiapine at night prescribed btw, right now im just taking the last 3 in very low doses)
