I need help! So I have smoked weed on and off most of my life!.......I had a bit of a break and have recently returned to it.........After a bong hit it burned and the next day I couldn't breathe properly!! I though this unusual so tried it a few more times with the same outcome! So I went on to smoking a joint with a small amount of tobacco and although I can smoke more this way I still eventually cant breathe!!!!! I am an ex smoker of tobacco and I tried a few cigarettes to eliminate the tobacco and yes I was ok!!!! The conclusion is its the weed!!!!! OMFG!!!!!! Has anyone else had this and any ideas what to do..................So frustrating~!
