I'm of a different mind. So much legislation is written on behalf of
insurance companies. Helmet laws, seatbelt laws, crash safety standards, you name it. They are one of the most powerful lobbies. They hire actuarials who crunch the risk numbers, and they are going to see that E-Cigs are going to SAVE them money. They will strike a deal with govt. whereby both arms benefit in 3 ways. Healthcare costs and insurance claims will go DOWN. Insurance co. profit will thereby go up. Govt will want a piece, and they only thing they can get their hands on is nic concentrate. Everything else about this is in the public domain, and can be easily made for "other purposes" (flashlights, etc.) Expect taxation at the nic level. BP and BT will want a cut, so nics will come from them, heavily taxed. Then the greed factor powers will get what they want, and give us what we will have whether they like it or not.
Your defense will be to lay up stock of nic concentrate before taxation, and buy your juices as "flavorings" without nic, and add your own concentrate. This will be the "grandfather" clause. Once those pre-tax stocks of concentrate are gone, they will have the control they seek and need. They you will see the insurance companies, govt, and BP PROMOTE the use.
