Vaping Can Lead to Smoking.

Several studies show people who vape are more at risk to smoke cigarettes. Teens who reported e-cigarette (vape) use were 6 times more likely to start using cigarettes than teens who never vaped, according to the American Academy of Pediatrics.

Nicotine in Vape and Cigarettes Causes Addiction.

Scientists have known for a long time that nicotine causes addiction. Nicotine affects the brain, and youth can become hooked on nicotine much faster than adults.  Researchers also found vape users have similar or higher levels of nicotine in their blood than cigarette smokers.

Vape flavors are often the same as food and candy flavors, but are they safe to inhale?

There are thousands of vape flavors from cotton candy to popcorn. According to the U.S. Surgeon General, the "nation’s doctor," many vape flavors are safe to eat in food, but the flavorings have not been tested enough to know if they're safe to heat up and inhale.

Chemicals in some e-juice can cause damage and swelling in the lungs.

Diacetyl is found in many flavored e-liquids like caramel, pina colada, and strawberry.  Diacetyl is also used to give food a buttery taste or to make sweet flavors. It's also blamed for a lung-damaging disease called popcorn lung. The name comes from factory workers who got sick after inhaling a lot of diacetyl while making microwave popcorn.

Cancer-causing benzene can be found in some e-cigarette vapors.

A chemistry professor measured benzene levels from e-cigarettes. One device, operated at high levels, had benzene levels thousands of times higher than the surrounding air. Benzene, a component of gasoline, has been linked to leukemia and other cancers.

Vape liquids may contain toxic metals like lead and chromium.

In 2018, a group of scientists published a report after testing 56 e-cigarette devices. They found e-cigarettes possibly expose users to toxic metals including lead and chromium. The scientists believe the heating coils inside the devices are to blame. Toxic metals from the coils transfer into the e-juice, which is inhaled by the user. The scientists say more study is needed to learn the full health effects. Other research links chromium to cancer and lead to heart disease and cancer.

Vapes can contain harmful chemicals like toluene.

Scientists tested vapors from 12 models of e-cigarettes looking for the same toxins found in tobacco smoke. The vapors from most models tested included toluene. Toluene is a volatile organic compound found in paint thinner and some types of glue. Toluene can cause kidney and liver damage.

Vaping may be less toxic than smoking cigarettes, but we still don't know all the facts.

A study for the National Institutes of Health looked at toxic chemicals in vape devices and cigarettes. The scientists found, in most cases, toxic chemicals in cigarette smoke were 9 to 450 times higher than levels than vapor from e-cigarettes. So vaping is considered less harmful than smoking, but still not safe. And there's still a lot we don't know about vaping because it's so new. No one has completed a long-term test of the health effects.
