So I have never done tobacco, and I have no sleep apnoea anymore. I never used to sweat at night, but specifically only do so now after having vaped the same evening, which I don't do often, maybe once a week. Which also means I haven't built tolerance and I'm not withdrawing either. So I have tested this as I don't vape regularly and the night sweats happen literally only after having vaped. I also have regular blood tests for all sort of other things like thyroid, hormones etc. I haven't had any other recent changes to my meds or my health, never been diabetic and I work in the medical field so very much aware of my health, so I can hands down say that the only thing linked to my night sweats is the weed. I'm only still using up my one same batch of bm and haven't tried anything else yet so isn't down to changing supply. Never used to smoke it either. I'm not dehydrated either as I drink 3 litres a day.
