Hey guys I've been smoking hookah for about 4 years now. Never had any problems with smoking until recently. I used to take hits and exhale the smoke properly until recently this happened; I can't take hits properly and barely any smoke is coming out when exhaling. I don't know what's causing this, seems bizarre. Smoke is also coming out of nose. Could it be due to sinus problems? Has anyone experienced this?. Any help is appreciated.
