Getting a cigarette smell coming out of the air vents. Just bought the car and didn't notice a smell before.

Try changing out cabin filter and auto parts sells interior forgers from meguairs

I have to say that getting rid of a cigarette smell is almost impossible, that was the principle reason why I kicked the habit. I just switched from cigarettes to vapmod v-mod https://gypsyvapes.com/vapmod-vmod-900mah-kit and I have to say that the smell is many times better.

Getting rid of cigarette smell is nigh on impossible,without taking down the whole dash/heater matrix/a/c system.and steam cleaning the whole thing.you could try an aerosol spray(from a dealer)that you spray into the outside air vent,but that only maskes it,unless it is very strong.(the nicotine sticks to everything)smoking should be banned in cars......same as cellphones.....
