A good friend has a son who smokes tobacco. She asked if he could vape tobacco, as she knows I vape cannabis vs combusting. I know nothing about this and she wants him to reduce tobacco risk if he can't quit. Any quick guideleines? Can you vape tobacco? What temps would be the target temps? Would vaping it be healthier (less harmful) than e-cigs and their extra elements in the carrier juice?? Thanks for any help/ suggestions to pass on.
