I am in the process of quiting cold turkey, just moved to a drug free house. Form my experiences i can definetly say that being high made me terrible at gaming girls. I was almost always high when i was around hbs...about half of them smoked or did some kind of drugs as well. I can say just about everytime i woke up without a girl all i could think about was all the ioi's i recieved the night before and how easily i could have closed the deal. I tend to get really f-ed up to a point where i can barely function and when i can i'm usely too paranoid to make my move. But i never really thought about it too much cuz i could always just get high. SO yeah definetly cut back man. Drugs are bad but if you need them i'd say stick with bud. Other drugs won't improve your game either, trust me i field tested it. sex is my drug of choice so i guess you have to decide what yours is going to be.
my 2 cents

The key is moderation. You don't want to be blazed all the time, but at the same time it can give you a new perspective and also challenge your social skills. Like a baseball player who practices with two bats before a game, being high in social situations can be challenging (because your so paranoid) but if you can overcome it, it surely helps with your ability to deal with comparable situations sober. And it can be fun. Smoking pot in modersation is not a bad thing.
