3. Addictive nature of vaping
- Nicotine content. Vaping can deliver highly variable doses of nicotine, depending on the e-liquid used, which can easily lead to addiction. Many e-cigarettes also allow users to vape more discreetly and frequently, which can increase overall nicotine exposure. Thus, vaping is certainly a clear pathway to forming a nicotine addiction.
- Chemical exposure. E-cigarettes contain and can release other harmful substances, including metals like lead and chemicals like formaldehyde, which are toxic when inhaled.
- Behavioral factors. The flavors and the physical act of vaping can be appealing, especially to younger individuals, reinforcing the habit and potentially leading to nicotine addiction.
Long-term effects of nicotine via vaping
- Cardiovascular issues. Chronic nicotine exposure, even from vaping, is linked to cardiovascular problems, including increased heart rate and blood pressure and potentially increased risk of heart attack and stroke.
- Respiratory problems. Long-term vaping can lead to lung irritation and chronic bronchitis and has been associated with a condition known as EVALI (e-cigarette or vaping product use-associated lung injury).
- Cancer risks. While vaping is generally considered less carcinogenic than smoking cigarettes, the long-term inhalation of some chemicals found in vape juice could potentially increase cancer risk.
- Dependence and other substance use. Continued nicotine use through vaping makes quitting difficult, and nicotine addiction may lead to the use of other addictive substances, particularly in younger users.
Overall, while some studies have suggested specific contexts where nicotine might offer cognitive or functional benefits, at the Everyoung.com Research Centre, we are confident that these do not outweigh the substantial addiction risk and adverse health impacts associated with its use, particularly through methods like vaping.
