As the government keeps trying to snuff out the E-Cig industry, all I can say is vaping has been a success for myself and millions of others. As you can see from my banner above, It's been 4 years plus since I last smoked a real cigarette and saved a lot of money.
Of course the government doesn't care if millions quit smoking. They're more concerned about the tax dollars lost from all us former smokers.
Kicking the habit was one of the best things I ever did.
