Determining a harmless level of nicotine depends on various individual factors including body weight, metabolic rate, and overall health. However, for most adults, nicotine exposure up to 5 milligrams per kilogram of body weight (mg/kg) is generally considered to not be lethal. Yet, it's important to remember that any amount of nicotine can be harmful, especially for non-smokers, children, and pregnant individuals. Nicotine can lead to dependence and has adverse health effects, so caution and responsible usage are paramount.
