Electronic cigarettes (also called e-cigarettes) are battery-operated devices that have a chamber filled with chemicals. They use heat from the battery to turn the chemicals into a vapour. The vapour is then turned into an aerosol that is inhaled by the user and called vaping. E-cigarettes include electronic nicotine delivery systems (ENDS), mods, vape pens, vapes, e-hookahs, and JUUL (a brand of e-cigarette).
Some e-cigarettes look like regular cigarettes, cigars, or pipes. Newer types of e-cigarettes even look like pens, phones, car fobs, and USB flash drives.
Some e-cigarettes are disposable (only used once). Other types of e-cigarettes are reusable (can be used more than once). The chamber (called a cartridge or pod) of reusable e-cigarettes can be replaced or refilled with a liquid that has chemicals. This liquid is often called e-liquid or e-juice./
At this time, it’s hard to know what’s in e-cigarette liquid. This is because an e-cigarette label doesn’t have to list all the ingredients. E-cigarette liquid often has:
It’s important to remember that when a chemical or other ingredient is safe for food, it doesn’t mean that it’s safe to inhale into the lungs. For example, Health Canada makes sure that flavours added to food are safe. But we don’t know if these same flavours are safe for use in e-cigarettes. Some research shows that added flavours used in e-cigarette liquid can cause lung problems.
E-cigarette liquid may have nicotine, even if the product says it’s nicotine-free. All nicotine salt cartridges (pods) have nicotine.
Nicotine is an addictive drug.
More research is needed before we know if e-cigarettes are safe to use. We also don’t know what the long-term health effects are. We do know that e-cigarettes:
If you use vaping products like e-cigarettes, make sure to buy them from a legal source that you can trust. If you buy vaping products from somewhere illegal, there may be more risks to your health and safety.
Read the instructions on how to use a vaping product before you use it. Don’t change the vaping product or use it with anything that you’re not supposed to use it with. If a product isn’t for vaping, don’t vape it.
Most places treat e-cigarettes the same as tobacco cigarettes. This means they can only be used in specific areas where smoking is allowed.
It’s best not to use e-cigarettes indoors or in vehicles. This can put others in contact with the harmful vapour from e-cigarettes (called second-hand vapour). The chemicals in second-hand vapour can be especially harmful to children and pregnant women.
Some early research shows that using e-cigarettes may help some people quit smoking. But we still don’t know how helpful they are and more research is needed.
We do know:
If you use e-cigarettes to quit smoking, it’s best to have a plan to quit using them at some point too.
Talk to your doctor about ways to help you quit smoking or using e-cigarettes.
This may include:
Over-the-counter products and prescription medicines to help you stop smoking are safe. Research has shown they can help people stop smoking and using tobacco products, or use them less.
You can also get support and information from Alberta Health Services if you’d like to quit smoking or using e-cigarettes.
