I know it's a strange question but my hubby wants to vape instead of smoke. Great. Only trouble is he has a sever caffeine allergy. I mean terrible the slightest bit of caffeine and he is ill for weeks.
It's that bad he can't drink wine. Spirits , and certain beers as they use coffee beans to add colour and depth of flavour.
Do you know if they add caffeine or coco to vaping liquids?
