can cigarettes soothe asthma problems? (read description)?

No. If anything, they make it worse.

This happens because when you smoke, you are actively breathing.

When you are doing your normal daily stuff, you are not filling all of your lung space with air. You are not consciously breathing, its part of your body's autopilot. When you smoke, you take breathing off autopilot, and breathe deeper. With you breathing deeper, your lungs feel better and you are better able to breathe.

Cigarettes do not help lung function. In any way, shape or form. They will only hurt your lungs and your breathing. Every cigarette you smoke puts tar into your lungs, and this prevents them from working properly. So in the moment you may feel better, but each puff just makes your lungs worse, and your asthma worse.

Stop smoking and see a lung specialist.

You are probably increasing CO2 levels by smoking and this is helping. It is suggested that shallow breathing rather than deep breathing can help, see e.g.

Some chemicals may dilate the tubes in lungs, but only temporally, if not then it's definitely a placebo. I'm sure you know persistent smoking will eventually cause you stop breathing in one way or another. So don't venture into this anymore.
