What Causes Difficulty In Swallowing While Smoking Marijuana?

Difficulty burping when smoking marijuana?

I'm 19 years old, approximately 5'9 and 150 pounds. I've been a daily marijuana user for about 3 years now, just using recreationally. Recently I picked up some bud and I'm getting a really weird effect from it when I smoke it. I'm smoking from a bong, and usually within a few minutes of smoking I can feel chest gas moving around and I have this feeling that I need to burp. When I try to burp nothing happens and it's almost as if my asophagus is swelling up. When I swallow, the spit goes down very slowly and I can feel it move all the way down into my stomach. I can breath completely fine, it hasn't seemed to effect my trachea at all. But just being a worrysome person, I feel as if something is wrong. When I sober up, the effect seems to diminish, although I have been able to let out a few small burps when it happens - not right away though, just after awhile of attempted burps and annoying chest gas that moves about.



This has never happened to me before so I'm just wondering if it may be an effect I'm starting to gain from weed in general, or if it's the strain that I have. I have not yet tried smoking different bud other than the bud that gives me this effect, since it has started happening.



Insights would be helpful and appreciated.
