E-cigarette popularity has increased and with that another possible source of toxicity. The most recent MMWR shows how e-cigarette use has increased over the past 5 years. The general toxicity involves nicotine toxicity with nausea, vomiting, eye irritation as the major sources of toxicity. Only one reported death where the nicotine reservoir was accessed and then injected IV in a suicide attempt.
There are some reports of asthma exacerbations but is more likely due to the vapor flavor and not the nicotine.
