^ wtf??? correct me if im wrong but when u drink u disturb the acids and digesting food in ur stomach, causing it to release gases which u then burp. smoke is smoke, its not solid it wont make u burp. generally after i smoke i get dry mouth, so no i dont burp intil i drink something
I do and it's because after I finishing pulling in the smoke, I swallow cos my throat is a little burny. As I am still kinda sucking in air, I end up swallowing the air. It's a common reason why newbies feel ill - they can't burp up the air in their stomach (also, they're often not used to smoking and get sick that way).
I think the smoke gets stuck in your lungs sometimes. It could also be that you swallow a little bit of the smoke and it goes into your stomach.
