Well, even if worst came to worst...
You could make your own tobacco-
juice from your own tobacco, and be guaranteed that there is less toxins in your home-made (For yourself only), nic-juice.
Yes, it would contain some of the tar, and some of the other 2000+ chemicals... but it would not contain any of the waxes, urea, formaldehyde, etc... that are on the papers, for flavor and to reduce the speed that the paper burns.
Eg, it could not be any more harmful than smoking a cigar.
Since you only need 1/10th of a cig's worth of tobacco to make a cig equivalent in juice... two cigs would make you a packs worth of your desired intake. That is still 1/10 of the potential harm of smoking, even if you were to ignite it, and add paper-juice to the mix.
There is always snus, which is like uber-mild chew. (Mild because you don't spit, you swallow the tiny bit of juice. It doesn't make you salivate as much as chew.)
Seriously... Look at everything else in the world... E-cigs won't die... At the worst case scenario, they just move underground. (At which point I am sure it will eventually cause harm, being uncontrolled and mixed at the hands of drug-dealers. LOL. Just like marijuana, and alcohol when it was in prohibition.)
The device itself is not illegal, or inherently harmful in any way. It is only the juice-contents, and advertising claims that are under scrutiny. Contents will be disclosed, no matter what, and who actually cares about advertising.
Translation... Politics has no power, just a large bark, and a big bite. As long as cigarettes exist, so will any alternate method of consumption of nicotine. (Ironic that they continue to waste smokers money, keeping the quitting devices in the market. Since cigs deliver only 10% of the poison they store, that leaves 90% available for 1/10th the cost of the actual cig. If they were smart, they would push for this. They are the ones selling the juice. Filters, papers, chemicals are all overhead to them. No-one will get rich selling e-cigs... not long term. It is the juice that is the investment winner. Well, the winner will be the one who comes-out operating under the law, not above it.)
Have no fear... if there is money involved... it will stay available... legal or not... it will never die.
Also note... Snus tins, made by camel-cigs, are great storage for e-cigs, and other treasures. Better than altoid-cans!
