E-Cigarettes do not "burn."

E-Cigarettes; San Francisco has decided to ban the sale of e-cigarettes in 2020, hoping to curb a surge in vaping among adolescents. But is the policy backed up by the available evidence? Unlike tobacco cigarettes, e-cigarettes do not “burn.” The devices, which have been available in the US since 2006, work instead by heating up a liquid that then turns into vapor and is inhaled.

Because of this, e-cigarette users don’t get exposed to the estimated 7,0000 chemical constituents present in combustible cigarettes, and vaping is generally believed to be safer than smoking. The liquids do, however, contain nicotine, which has been studied for decades and is known to be highly addictive.

Butter flavoring to microwave

There is also “substantial evidence” that the vapor contains traces of metals, either from the coil used to heat the liquid, or other parts of the device. Another potential red flag, according to the Centers for Disease Control and Prevention is the presence of diacetyl; which is use to add a butter flavoring to microwave popcorn; but has link to a serious but relatively rare lung disease.

Market leading maker Juul’s response to the San Francisco ban was that it would “drive former adult smokers who successfully switched to vapor products back to deadly cigarettes.” A study publish in February in the New England Journal of Medicine on a group of 886 patients in Britain’s National Health Service found the claim to be true.

The one-year abstinence rate among e-cigarette users was 18 percent, compare to 9.9 percent among a group who use other nicotine replacement products like gum or patches. The conversions are not, however, all in one direction. A slew of recent studies have found that, among adolescents; so e-cigarettes effectively provide a gateway toward full-fledge smoking.

Authorities are worry that decades of declining smoking rates; hence among this demographic could go up in smoke as a result of these devices. The vaping industry is adamant it doesn’t want to see underage people; so using its products and more must be done to prevent their sale. E-cigarettes are already; so illegal to sell in the US to people under 18 or 21, depending on the state.

Access to e-cigarettes

But, the sector argues, bans are a poor policy choice because; so they deprive adults addict to smoking of a valuable tool. To deprive those smokers from access to e-cigarettes; which we know are substantially less harmful, I think is a terrible decision, ” Neil McKeganey, of the UK-base Center for Substance Use Research base; which is partly fund by the industry, told AFP.

The irony is that the sale of alcohol, cigarettes and cannabis will remain legal in San Francisco for those over 21. The risks associate with all three are well studied. For alcohol, these include liver disease, high blood pressure and heart disease, numerous cancers. For cigarettes, heart disease, stroke, lung and various other cancers.

Numerous papers meanwhile have explore the risks of cannabis particularly on the juvenile brain. In place of bans, makers want to see tighter regulation. There is a lot of work to be done: an analysis of Californian vendors publish Monday in the medical journal JAMA find that almost half of tobacco; also vape shops did not ID young customers looking to buy vape products.
