You are reinforcing just how important proper regulations are. I, however, disagree with the figures put forward by the Canadian Cancer Society. From a methodology perspective, respondents were asked whether they had ever tried e-cigarettes. Everyone here today probably has children. Do you know a single teenager who hasn't tried smoking? Trying something does not mean taking it up as a habit. In its study, the Canadian Cancer Society asked people whether they had tried e-cigarettes in the past month or six months. They were not asked, one year later, whether they had continued smoking regularly. Like the Canadian Cancer Society's study, certain American studies do not ask respondents that question either.
In light of that, I think we should be looking to Europe, specifically England and France, which produce statistics on a monthly basis. Those countries could supply us with data on how many people regularly use e-cigarettes. Some argue that the price of e-cigarettes will drop over time. But a hundred dollars is a heck of a lot of money for a teenager to drop on an e-cigarette when they walk into a vape shop for the first time. That does not promote regular e-cigarette use.
What's more, the user has to have a bit of discipline. They have to fill the tank every two or three days and exercise caution when doing so. They also have to charge the battery and change the heating element regularly, as it wears with time.
At the end of the day, it's easier for them to walk into a convenience store and buy a pack of cigarettes than it is to use e-cigarettes. Using e-cigarettes requires some discipline.
