E-cigarettes are small, battery-powered devices that usually look like cigarettes. The e-cigarette cartridge is usually filled with propylene glycol, which makes the vapour, and glycerol. Some cartridges also contain flavouring. People may use e-cigarettes to simulate the feeling of smoking without actually smoking tobacco.
Many e-cigarettes also contain nicotine. Different brands and models of e-cigarettes have different amounts of nicotine. When you puff on the e-cigarette and inhale the vapour, the nicotine enters the lungs as a vaporized solution.
E-cigarettes with nicotine have not been approved by Health Canada for safety and efficacy. They can’t be sold legally anywhere in the country. Researchers are still looking at how effective e-cigarettes with nicotine can be in helping someone quit smoking. Some studies have shown that e-cigarettes with nicotine may help users quit smoking. More research is needed.
E-cigarettes that don’t contain nicotine can be legally sold in Canada. However, researchers haven’t shown that they are effective in helping people quit smoking. A few studies have shown that there may be low levels of harmful substances in some e-cigarettes, even if they don’t have nicotine.
