Vape vs Tobacco. Are they really safe?

E-CIGGS - Are they safer than tobacco? Or are they a high-tech way to hook a new generation on a bad nicotine habit?

Nobody knows yet.

Research into the effects of e-cigarettes lags behind their popularity. But ready or not, the era of e-cigarettes is here. It’s a booming, billion-dollar industry -- on track to outsell tobacco products within a decade. The number of teens using these products doubled between 2011 and 2012. 

Are They Safe?

The nicotine inside the cartridges is addictive. When you stop using it, you can get withdrawal symptoms including feeling irritable, depressed, restless and anxious. It can be dangerous for people with heart problems. It may also harm your arteries over time.

So far, evidence suggests that e-cigarettes may be safer than regular cigarettes. The biggest danger from tobacco is the smoke, and e-cigarettes don't burn. Tests show the levels of dangerous chemicals they give off are a fraction of what you'd get from a real cigarette. But what's in them can vary.

"E-cigarettes may be less harmful than cigarettes," Drummond says. "But we still don't know enough about their long-term risks or the effects of secondhand exposure."

Opponents say that because nicotine is addictive, e-cigarettes could be a "gateway drug," leading nonsmokers and kids to use tobacco. They also worry that manufacturers -- with huge advertising budgets and celebrity endorsements -- could make smoking popular again. That would roll back decades of progress in getting people to quit or never start smoking. 

Others look at possible benefits for smokers. "Obviously, it would be best if smokers could quit completely," says Michael Siegel, MD, MPH, a professor at Boston University's School of Public Health. "But if that's not possible, I think they'd be a lot better off with e-cigarettes. They're a safer alternative."

Siegel compares replacing tobacco with e-cigarettes to heroine users switching to the painkiller methadone. The replacement may have its own risks, but it's safer.

Some supporters believe that e-cigarettes could help people quit, just like nicotine gum. Initial research looks promising, but more long term, in-depth studies are needed.

What Parents Should Know

• Nicotine can affect brain development in children and teens, Drummond says.
• Some e-cigarettes have candy flavoring, which could make them appealing to kids.
• They don't leave a smell like tobacco. So it's harder for parents to know if their kids are vaping.

What Adults and Smokers Need to Know

• If you don't smoke, don't start vaping. There are no health benefits and some risks.

• If you smoke and are trying to quit, you're better off with an FDA-approved method of quitting, Drummond says, like the nicotine patch or gum. There's good evidence that they help. E-cigarettes may turn out to be an effective way to quit, but we don't have the proof yet.

• If you're not planning to quit, would it be healthier to switch from tobacco products to e-cigarettes? Maybe. Talk to your doctor about the risks and benefits.
