Some good reading here!! I to took my PV to my doctor 2 days after getting it and he also gave me the 2 thumbs up!! I however could not convince him to right a perscription for nicotine as my last order from Nhaler was stopped coming into Canada and got sent back! He has seen me since and is very excited that I have now been of analogs for 94 days... not a single puff!! I smoked 2 packs of Players original (about as strong as they get here in Canada) and havent felt better in years!! My dentist also gave me the 2 thumbs up and wanted as much info as possible to give to his other patients. These are all things that eventually will change peoples minds on this! vape on!!
