One thing to consider as a possibility is if you feel guilty, in general, when you smoke. Some people worry so much about "breaking the law" or what others might think of them, among other things (albiet subconsciuosly most of the time) that they can't enjoy the "high." Just something to consider. I heard a theory similar to this that was expanded upon and explained much more in-depth that started to make a lot of sense. I kinda stole it. lol. If I can find it, I'll link it. I realized, in hindsight after considering this theory, that when I first began smoking when I was younger, I would suffer from increased social anxiety from time to time. I have for the better part of my life, been a very quiet individual and kept to myself, straight or not. My parents said that I didn't even cry as a baby. I've always had plenty of friends, but the anxiety I felt, May have something to do with being an only child and being used to being alone, but Idono. Anyway, when I went through my early teenage years and started to go through the "Not Giving A Fuck" phase, the highs were much better because I wasn't worrying about what people thought. I guess now, I "Still Don't Give A Fuck" because I am much more outspoken now, especially regarding cannabis/hemp and I can say that the plant has helped me in a sense to not care about what people's prejudice may be and just live life. What I'm saying may not make too much sense since I'm throwing stuff in and hoping it comes out right, but I hope you can get the gist of what I'm trying to tell you to consider a possibility for your anxiety as it relates to smoking marijuana.
