If it's a true allergy then I'd say it's a smoke allergy but get tested just in case it's tobacco related. If it is tobacco related you might have options via shots but more likely you'd have to give it up. A smoke allergy can also be treated but more likely you'd only have to slow down your intake dramatically. Another option is it could be a sensitivity to chemical properties in the tobacco and if it's something like that then you can build an immunity to that eventually. Asthma might be possible but only if you're dealing with inflammation on top of the congestion. No matter what it may be for you just go and see an allergist asap. I know people hate the doctor but all a doctor is gonna give is an opinion which doesn't hurt at all. Good luck brother!
