Vapes – How do they work?

Vaping devices heat a solution to create an aerosol that is inhaled. The solution typically contains nicotine, propylene glycol, vegetable glycerine and flavourings.
Like NRT, the nicotine in a vape reduces the urge to smoke and is an effective substitute for smoking, delivering nicotine without harmful tobacco smoke, tar or carbon monoxide.
More frequent and consistent vaping is typically needed to get sufficient nicotine (grazing).
Maximum nicotine concentration is 20mg/ml. Some heavily dependent smokers may benefit from using a vape combined with patch.

Possible side effects

Dry mouth and tickly cough- encourage increased water consumption.
