When sober, I can never quite block everything else out and focus entirely on the emotional impact of that particular moment. Often when I'm upset about something or really having trouble mulling over a particular decision in my head, the solution will seem obvious within 10 minutes of lighting up that after-work bowl. The possibilities seem endless.
I'm very long term solution oriented when it comes to matters of self both mental and physical. I see any issues as my body trying to tell me to make changes someplace, finding where isn't always easy but is always worth while.
Being an ENTP, I know that feeling you're talking about, not being able to block everything out. I see smoking as a way of achieving that a cop out that avoids growth and prolongs a permanent resolution. I have an ENTP friend that has an after work bowl, he has been doing the same cycle for at least the past 6 years. He smokes cause he likes to, smokes cause he needs to, quits cause he feels like he doesn't have control, smokes cause he likes to, smokes cause he needs to, quits cause he feels like he doesn't have control. I find the whole thing pretty damn funny honestly.
I have never drank, never smoked, never done any drug of any kind in fact. I have yet to avoid any problem I've ever had in my life. To take that edge off and clear my head, I meditate. This has allowed me to gain control over yet another aspect of my life, my intense, out of control and insane Ti. Having done so I think puts me at a distinct advantage, our Ne Ti working together can be amazingly insightful and gives us such an edge. That feeling you have is you trying to gain control over those as they often times conflict, don't line up or send confusing mixed signals. Smoking may slow that whole process down but the goal is to understand it not slow it down. With understanding you will have the same outcome without any loss of ENTPness.
I like this quote about meditation and I'm putting it up because somebody is bound to comment on it being pointless.
“We could say that meditation doesn't have a reason or doesn't have a purpose. In this respect it's unlike almost all other things we do except perhaps making music and dancing. When we make music we don't do it in order to reach a certain point, such as the end of the composition. If that were the purpose of music then obviously the fastest players would be the best. Also, when we are dancing we are not aiming to arrive at a particular place on the floor as in a journey. When we dance, the journey itself is the point, as when we play music the playing itself is the point. And exactly the same thing is true in meditation. Meditation is the discovery that the point of life is always arrived at in the immediate moment.”
I'm not a prude, I don't care if people smoke weed, I don't care why people smoke weed. I have decided to comment only because the op was another ENTP and I understand the situation and can contrast it with another ENTP that has made a different choice. I will say my friend is far less balanced, tends to avoid people more than I, far more flighty and seemingly never finds any peace or rest in his own mind. He has prety much withdrawn from all but his small inner circle of friends and most people don't get him at all. Not saying that has to do only with smoking but I'm sure it comes into play.
