Vaping and e-cigarettes

Vaping devices are battery-operated and heat a liquid (e-juice) into a vapour that is inhaled. E-juice contains propylene glycol, flavouring and other additives — it does not contain tobacco, but most varieties contain nicotine, the same addictive substance found in cigarettes.

Vaping is the act of inhaling and exhaling an aerosol produced by a vaping product, such as an electronic cigarette.

Youth and people who do not smoke should not vape. Vaping is not harmless and is not a proven quit-smoking aid.

Youth and vaping

In Niagara, 54 per cent of secondary school aged youth vaped at least once in their lifetime which is higher than tobacco use (Ontario Student Drug Use and Health Survey, 2019).

Nicotine is especially harmful to young people. It can interfere with brain development, and affect memory and concentration. It's important for youth to know that vaping can be addictive and not just harmless water vapour.

The law

Under the Smoke-Free Ontario Act, it's illegal to:

  • Vape in public places
  • Sell or supply e-cigarettes or e-juice to anyone under 19
  • Vape in a vehicle when a person under 16 is present
  • Allow anyone under 19 to enter a specialty vape shop

Parks and playgrounds in Niagara are smoke-free. This applies to tobacco, vaping products, cannabis and waterpipes. Learn about smoke-free outdoor spaces and by-laws in Niagara.
