I don't think you'd have any problem Becky. The addiction threshold I understand is about the equivalent of a half-pack a day, or as suggested by the New England Journal of Medicine, at 5 mg. It really depends how much of that 3-4 mg Tribeca you enjoy. Personally I think smoking, aka vaping, is far more socially addicting than anything else. 
Won't you PM the link for that Tribeca clone you enjoy so much, will you?
