I want the food that I buy in the grocery store regulated. Nicotine is toxic and there have been injuries and deaths from the liquid concentrates used in e-cigs. Carelessly produced liquids could be a hazard even if used in the standard way. The industry and users need to insist on reasonable regulations to keep the product safe. E-cigs hold the promise of being a safer way to use tobacco, and one that is more polite. You don't want to fill up your e-cig, take a puff, and hope the medics arrive in time.
Let me make it clear that my previous post does not constitute an anti e-cig view. You do not want to buy medicine from black-market manufacturers. You want your hamburger to be from regulated sources. You would not want your e-juice to be 10 times as potent as you think it is. Quality regulation is reasonable and desirable. I am a pipe smoker and wish there were e products that would suit me.
