Congrats on your options!
Is the Tobacco company well known? Can it immediately be recognized in the US or Europe or wherever you may be recruiting next? If not, then I would not consider it a good move per se unless there is something greater to it. Also a Tobacco company sounds a bit daunting and a bit of a niche industry that gets a lot of flack. You don't want that rubbing off onto you.
The average lifespan of a startup is not long, esp in this kind of environment but sometimes these are amazing options and opportunities - imagine joining Microsoft or Tesla when they were just starting out. The salary bump sounds amazing. My suggestion would be to negotiate a provision for a 6-12 months severance should you be laid off (if that's within your power). Obviously if they go bankrupt they can't pay you but if they are still alive and just laying off staff, you will either have the job or a severance. You can justify it as "I am leaving a very stable and strong job but if you lay me off in the next 3 years, I would not be able to go back to my employer and would be struggling; is there a possibility that for the next 3 years you give me some protection to help provide for my family " not sure how it will play out but you are not asking for money, not yet at least
