IMHO. I can see that and more. If vaping has real long term sustainable growth and I mean practically exponential, the government and big tobacco concerns will step in to "regulate" the industry. Economically, I think, they would have to. You can't have an unregulated industry, like vaping, subplant possibly the oldest economic institution in the country, i.e., tobacco. Vaping is basically in its infancy and look at the legislation and proposed legislation to regulate and control it already.
Lobbyists and politicians will bombard the media with messages of doom and gloom for the economy if eliquid manufacturers are allowed to produce their product w/o the regulation of the government. Then, they'll point fingers at the eliquid producers in China and tell us how they're taking American jobs while poisioning the citizens of the United States. Lastly, the medical industry will step in tell us that vaping is no better or worse than smoking and that they can say that because of the lack of medical evidence to the contrary.
When all is said and done, you'll have eliquids and paraphernalia regulated, just like tobacco. There will be a few companies given government blessings to mass produce inferior products and there will be outrageous costs to purchasing them.
Just my opinion though. Sorry if it's a bit of a rant. Any thoughts?
