I have previously posted a note about e-cigarettes (see: GlaxoSmithKline Lobbies Against E-cigarettes; Motivation for Company Clear). I personally have come to the conclusion that these devices serve as an on-ramp for turning teenagers into nicotine addicts. They come in various flavors and are non-irritating to the throat and trachea, providing an appealing set of inducements. Another threat about which I was not previously aware is that calls to poison centers relating to e-cigarettes have surged in recent months. Another reason to get the product off the store shelves (see: E-Cigarette-Related Poison Center Calls Surge). Here is an excerpt from the article:
Calls to poison centers involving e-cigarettes have surged during the last 3 and half years, a new study shows. The number of calls shot up from 1 per month in September 2010 to 215 per month in February 2014, researchers for the Centers for Disease Control and Prevention report...."This report raises another red flag about e-cigarettes — the liquid nicotine used in e-cigarettes can be hazardous," said CDC Director Tom Frieden...."E-cigarette liquids as currently sold are a threat to small children because they are not required to be childproof, and they come in candy and fruit flavors that are appealing to children. "More than half (51.1%) of the calls to poison centers because of e-cigarettes involved children 5 years and younger....Many states do not restrict the sale of e-cigarettes to minors. The number of calls per month involving conventional cigarettes did not show a similar increase during the same period. Poisoning from conventional cigarettes is generally caused by young children eating them. Poisoning related to e-cigarettes involves the liquid containing nicotine used in the devices and can occur in 3 ways: ingestion, inhalation, or absorption through the skin or eyes. Among the calls involving e-cigarettes, 16.8% were for inhalation, 8.5% for eye exposure, 5.9% for skin exposure, and 68.9% for ingestion ....Calls about e-cigarettes included reports of adverse health events 57.8% of the time, with vomiting, nausea, and eye irritation being the most common complaints.
I suspect that the majority of adult smokers do not understand the toxicity of nicotine and thus may leave cigarettes and e-cigarettes within easy reach of children. Here's some details about nicotine poisoning from the the Wikipedia (see: Nicotine poisoning):
Historically, most cases of nicotine poisoning have been the result of use of nicotine as an insecticide. More recent cases of poisoning typically appear to be in the form of Green Tobacco Sickness or due to accidental ingestion of tobacco or tobacco products or ingestion of nicotine containing plants. The probable lethal dose of nicotine has been reported as between 40 and 60 milligrams (the total amount in about 2 cigarettes if all of the nicotine was absorbed) in adults and about 1 mg/kg in children (less than 1 cigarette). Children may become ill following ingestion of one cigarette, ingestion of more than this may cause a child to become severely ill.
As noted above, e-cigarettes contain a reservoir with a nicotine solution with flavoring that can be attractive to children if these devices are not secured in homes. This liquid is vaporized with a heating element and inhaled with an e-cigarette. Hence, the term "vaping" that is used by young people to describe their use of e-cigarettes. This liquid in e-cigarettes can be ingested by children. It's only now that some cities are banning the sale of e-cigarettes to minors as in Philadelphia (see: Vape No More: Nutter to Sign E-Cigarette Regulations). My opinion is that e-cigarettes are dangerous and should be declared illegal.
