Oh no! The gray market may turn into a vaping black market. In that hypothetical, costs may actually go down (hypothetically speaking) and so I'd find my dealer(s) and proceed accordingly. If hypothetically, it turned into a heavily regulated and heavily taxed market, I'd hypothetically quit cold turkey and hypothetically have no problems doing so. Ya know, since I actually did quit smoking cold turkey once in my adult life for 8.5 years.
