Nicotine is addictive. The 2022 OHID review attributes only a small part of smoking’s harms to nicotine; this comparison concerns smoking-related harm and does not mean that all nicotine effects are minor. Effects and risks depend, among other things, on age, health status, dose and how it is used.
Nicotine in Smoking Compared with Vaping
Smoking tobacco involves combustion and exposure to a large mixture of harmful substances in smoke. Vaping does not involve the combustion of tobacco, so completely switching from smoking to vaping may reduce exposure to many of the toxic substances in smoke. Prolonged dual use of both methods does not provide the same reduction in exposure.
The amount of nicotine that reaches the body through vaping is not fixed. It varies according to the device, liquid concentration, power, frequency and duration of puffs, and usage pattern. Therefore, it is not appropriate to guarantee that a “specific concentration” will suit everyone.
Who Is Nicotine Not Suitable For?
Nicotine can cause dependence and is not intended for adolescents, non-smokers, or people who are pregnant. People with a medical condition or those taking medication should seek advice from a qualified healthcare professional, not from retail guidance.
Symptoms and precautions
Nausea, dizziness, palpitations, headache, or feeling unwell may be related to nicotine or other factors. A severe or persistent symptom requires stopping use and seeking medical care. Keep nicotine liquids and devices away from children and pets.
