smoking is the act of consuming ( inhaling) a form of tobacco that has been processed thru the means of combustion.
So, if you are not burning tobacco and inhaling it, you are not smoking.
If the question on the form asks if you are a smoker, then the answer is no.
But, if the question asks if you use/consume nicotine, then its a different story...
If you eat eggplant, califlower, green peppers, tomatoes, potatoes, for example, you consume nicotine... ( since those do contain nic. Patches, gum, vaping also contain nic but no tobacco. Chew and dip do consist of tobacco but its not smoking.
