Hello I have been vaporizing cannabis for a little over 2 years it is my preferred method of consuming. Although every time I vape I get like this thick spit or phlem in the back of my throaght. It feels like a ball of it in my throaght. Everytime I try to swallow it it comes back up shortly after with a small burp but it's not really a burp it's more somthing I do to get the odd sensation out Of my throaght. then I end up swallowing it again. sometimes I can cough it up a bit but then It comes back a few minutes later. I feel like it makes my stomach upset a bit to from all of the swallowing but never to the point of throwing up. I use both the dynavap and the pax 3. I also use wax cartrages sometimes. It happens with both flower and wax though. Anyways anyone have any ideas to why this may be happening? It sometimes makes breathing feel a bit weird when breathing in as well in the throaght area. I also feel it in my lungs but I think that is normal because you are still inhailing stuff into your lungs I also recently had my lungs checked and everything seems good! Im just wondering how to deal with this? Is it just cotton mouth? Or somthing else? Sorry for the somewhat graphic wording I just want to get my point across!
