Q: Is the smoking of vape haram? Also will the buying and selling of these products be considered as a Halal business/income?
A: Just as smoking cigarettes and selling them cannot be deemed absolutely haram (prohibited), the smoking of vape and its sale is not regarded to be absolutely Haram. However, the sale and consumption of such products are regarded as Makrooh (disliked) and not the best form of income, and is best avoided.
