After I started vaping I got my step-father to start. So, he has been vaping about 3wks now and he is still craving analogs. As far as I know he hasn't had analogs. The problem is that he has been itching like crazy. He's had to use tons of lotion and take baths to relieve the itching. Is it possible this is caused by an allergy to PG or is it from quitting the analogs? He has been smoking for 60 at least a PAD. I mixed him up some VG juice for now.
