You’ll hear from many places that the fatal dose of nicotine for an adult is between 30 and 60 mg, but this is estimate is actually based on an extremely questionable piece of science. The figure has been called into question by stories of people consuming over 60 mg and surviving, and from the measured nicotine concentrations in the blood of people who did die from an overdose. In short, it’s extremely unlikely that anyone would be able to consume enough liquid through vaping to overdose, but it’s still important to know the early symptoms of nicotine poisoning.
- Nicotine is assumed to be between 10 and 20 times less toxic to humans than commonly reported, putting the fatal dose for an adult at around 500 mg to 1 g.
- Symptoms of nicotine poisoning include nausea, dizziness, vomiting, abdominal pains, rapid heartbeat, excessive salivation and trouble breathing. If you notice any symptoms, take a break from vaping for a while – it’s nothing to worry about, but a sign you’re consuming too much!
- If the situation is severe – for example, you’ve accidently swallowed a large amount of e-liquid or have spilled a strong nicotine base on your skin – seek immediate medical care.
I am not sure how genuine this concern may be for the average vaper. In general, smokers (and by inference, vapers) titrate their nicotine intake based on the feedback they get from their bodies. Feeling dizzy or nauseated is a sign of too much nicotine. Feeling fatigued, dopey, and confused is a sign of not enough nicotine. As a result, nicotine consumers self-regulate nicotine intake to meet their needs. With the exception of those affected by active psychiatric conditions, it is uncommon for the average vaper to experience symptoms of severe overdosing (e.g. progression from agitation, nausea, vomiting, tachypnea, and tremors to loss of consciousness). In order to minimize nicotine overdose in first time vapers, common sense would suggest gradual nicotine up-dosing, starting with a low/medium concentration (depending on the nicotine level in their own brand) in the e-liquid
