I could be wrong, but I think most people who replied to this thread have never smoked. In fact, when you're stoned, just enough though, your ability to focus is higher than normal. It could be beneficial in a live game, but not online and especially not when multitabling.
But the problem is that you cannot stay in the same state of mind for a long time and you can certainly not measure how much you should smoke in order to "stay in the zone" enough to make a session profitable.
Consequently, get stoned when you want to relax and listen to some good music. Poker needs all your attention, concentration and patience.
this thread was almost 5 years ago and since then many times iv had good and bad decisions, and guess what, i also had the same experience sober...
its like the thing with drunk and driving have less crashes overall if you see stats about people crashing sober. 😵 bad analogy i know
