Can I smoke in bed?

I'm curious, is it SAFE to smoke in bed? I understand that smoking can be hazardous to one's health, but is there a specific risk associated with doing it while lying down in bed? Could it potentially lead to a fire or other dangerous situation? I'd like to hear your thoughts on this matter as a professional in the field of finance and cryptocurrency, as I'm sure you have a well-rounded perspective on various aspects of life.
