I agree people especially should not vape or smoke. This is about saving people that can't quit smoking by over the counter means or through pharmaceutical meds. This is about THR ( tobacco harm reduction). This is no way near 100% safe, neither is anything else in this world we live in. I going to guess you never smoked or vaped, so STFU and educate yourself on the subject matter. The library is a good play to start. It's the place where you can borrow books for a certain amount of time and return them if you have a special card. Check out "Stop Smoking Start Vaping" by one of the leading experts in the field Dr. Colin Mendelsohn.
