I recall seeing a program on a guy who was a little schizophrenic, basically he heard children voices and whenever and whereever he went out his door he would put on his earbuds on loud vol with music or go to his concerts to be calmed.
It's definitely understandable that one want to escape from anxieties, in his case listening to such music just isn't an escape, its rather the most direct route to potentially getting t or/and a hearing loss.
You know it's your choice whether you want to smoke or not, and I understand it may help on your anxieties in the moment you lit the smoke, knowing anxiety I just think the question and considerations you raise about smoking to escape t, shows the exact irrationality of anxiety. It's more easily said than done, bottomline is you're asking the wrong question imo, speaking from one with anxiety as well. It's the pattern of your question and the answer you're seeking which needs to be changed in order for it to get better
To try to break down the irrational part of your question let's clarify here;
you know it's a bad moove, you know there are chemicals in it which are if not ototoxic for your tinnitus, momentarily good for your anxiety while the worst thing you can do for every part of your body in the long run, including your anxiety.
I'm not saying you're the guy from my first example, but I want to point out having t does in no way justify you doing further harm to yourself!
Detoxing and stopping is quite a hurdle but necessary, secondly you need to find a replacement (drugs, alcohol..^^ well thats the next step down, it's still hard but thankfully you're not quite there). So what you need is something you actually like doing, to divert your attention and to replace the soothing you get from a cigarette. The side effect of this is your t will be there all the time and the odds of being able to enjoy what you like while having t, will greatly increase. At a point I remember a guy in here who drank a Lot to calm his anxieties and problems with t, many suggested he replaced it with doing what he liked, be it running, some kind of exercise and I remember seeing posts of him doing so and things taking a turn for the better
You might not have gotten the answer to your question you think you wanted, but as this is a support section you'll get exactly that!
