What is a nicotine allergy?
Nicotine can elicit an allergic response in individuals with a nicotine allergy. This occurs when a person’s immune system
mistakenlyTrusted Source attacks the body like it would with a bacteria or virus.

2018 study, 7% of smokers and 20% of non-smokers were found to have a nicotine allergy. However, this study only included 30 participants.
In some cases, a nicotine allergy can worsen existing health conditions. For example, if a person with a nicotine allergy wears a nicotine patch, it may trigger
contact dermatitis.

research from 2018, nicotine from unprocessed tobacco causes a stronger allergic response than nicotine from commercial cigarettes.
Anaphylaxis: Symptoms and what to do
Anaphylaxis is a severe allergic reaction that can be life threatening. The symptoms develop suddenly and include:
- hives
