How does vaping affect health?

There are several health risks relating to vaping, notably to lung and heart health. Other risks include the presence of nicotine, other harmful chemicals, exposure to second-hand aerosol, and device malfunctions.

What are the health effects of vaping?

The e-liquid in vaping products, which is vapourized and then inhaled, contains a variety of chemicals. The long-term risks of inhaling these chemicals are still being studied but research is starting to show negative effects on both lung and heart health.

 As investigations into vaping products and related lung illnesses continue, QuitNow recommends that you consider refraining from using vaping products.

General health risks of nicotine

Nicotine is not known to cause cancer. It is approved for use in nicotine replacement therapies, such as the patch or nicotine gum. However, there are risks linked to nicotine and it is a highly addictive substance. As well, exposure to nicotine from smoking is known to contribute to increased heart rate and blood pressure and to cardiovascular disease, and it is suspected that nicotine exposure from vaping has similar long-term cardiovascular effects.

Vaping products contain nicotine in various concentrations, compared to more standardized amounts found in cigarettes and nicotine replacement therapy. Some products contain much higher levels of nicotine than cigarettes. A single Juul pod can contain as much nicotine as an entire pack of cigarettes, and delivers this nicotine much faster and more intensely than smoking. The effects of these concentrations and inhaling nicotine aerosol are still being studied.

Vaping with nicotine can also lead to side effects like seizures or blackouts, due to inhaling too much nicotine in a short period of time. This is considered a form of nicotine poisoning. The majority of incidences have been among youth so far, according to US-based reports.
