Disclosure:

In the past 12 months, I have had no relevant financial relationships with the manufacturers of any commercial product or providers of commercial services discussed in this CME activity.  I do intend to discuss an unapproved or investigative use of a commercial product or device.

dedicated to protecting children from secondhand smoke, and ensuring that all clinicians ask the right questions about tobacco and SHS exposureSlide5

ObjectivesAt the end of the session, participants will be able to:

State what e-cigarettes are and how they are usedDescribe new information on the composition of electronic cigarette aerosol, and potential harmsCounsel teens and parents about the risks of adolescent electronic cigarette use, and how electronic cigarettes may lead to combusted tobacco useDescribe the current regulatory environment around electronic cigarettesSlide6

First Generation “Cigalikes

”AKA: minis

Examples: Blu, Logic, Vuse, Mark 10Can have manual or automatic heatingDisposable or RechargeableSlide8

Second Generation “Tank Systems”

AKA: Personal Vaporizers, Mid-size, Vape PensExamples: eGo, EVOD, Apollo, Halo, Vapor FiAvailable with many types of atomizers, batteries and mouthpieces

All rechargeableMost have manual heating buttonAvailable in tunable and non-tunable voltage batteriesUsually come in a kit for customizationSlide9

Third Generation “Mods”

Why?

Bold et al, Pediatrics, 2016Slide22

Gateway to smoking?

The adolescent brain appears uniquely susceptible to nicotine addictionAnimal studies have demonstrated that nicotine exposure during the adolescent period has long-standing effects in the brain including cell damage that leads to both immediate and persistent behavior changes.These effects are not found with nicotine exposure to the adult, supporting the idea that the adolescent is uniquely susceptible to nicotine addiction.

E-cigarette liquidSlide29

Constituents of e-liquids

Propylene glycol: general recognized as safeAcceptable for use in flavorings, drugs, cosmetics and as direct food additiveFew human studies for inhalation, however has been used as a tobacco humectant historicallyCan cause eye and respiratory irritationMSDS from Dow Chemical states “inhalation exposure to [propylene glycol] mists should be avoided”EPA cites a single rat study from 1947 for their inhalation effects)

Werley et al, Toxicology 2011Slide30

Other humectants

Vegetable glycerin: generally recognized as safeWhen heated and vaporized, can form acrolein, which can cause upper respiratory irritation For all: unknown long-term health impacts from repeated inhalationSlide31

Humectant Toxicity – recent evidence

Kosmider et al, Nicotine & Tobacco Research 2014Slide32

Nicotine

Not present in all e-liquidsNicotine effects: low dosesComplex pharmacodynamics – neural stimulant at low doses and a depressant at high dosesNicotine overdose Excess: nausea and vomiting, excessive salivation, abdominal pain, pallor, sweating, hypertension, tachycardia, ataxia, tremor, headache, dizziness, muscle fasciculations, and seizures

Death: several case reports of suicide by nicotineOne child death in the USNew regulations for child safe packagingSlide33

How much do you get per puff?

HIGHLY variable2013 study found 0-35 μg/puff, so minimum of 30 puffs to deliver the 1mg nicotine inhaled from a traditional cigaretteOnly part of the nicotine is vaporized, and of that 50-60% of nicotine is inhaledWide variability in vaping behavior of ten volunteers:Puff duration 1.8 +/- 0.9s, puff volume 70 +/- 68 ml, puffs/session 15 +/- 6.

, et al. Nicotine and Tobacco Research 2013Slide34

Factors that affect aerosol delivery

USER FACTORSPuff durationPuff volume

Puff profile (i.e. bell vs. square – machine smoking)User’s experienceDEVICE FACTORSSolvent (Propylene Glycol/Glycerin)VoltageWick design/efficiency

Draw resistanceAtomizer design (single vs. dual coil)Heating element resistance

Manual versus automatic activationSlide35

Design has large impact on aerosol delivery:Time dependent comparison of plasma nicotine

Flavors

V2: Eucalyptol, Camphor, Menthol, Pulegone, CinnamaldehydePremium: Eucalyptol, Camphor, Menthol, Pulegone, Cinnamaldehyde, Ethyl Salicylate

eSmoke: Eucalyptol, Camphor, Menthol, PulegoneSouth Beach Smoke: Eucalyptol, Camphor, Menthol, Pulegone, CinnamaldehydeSlide37

It’s just water vapor, after allSlide38

What are the harms of the aerosol?

Second-hand vapor is NOT just water vaporEmit variable levels of nicotine (1/10th that of cigarettes), plus fine particles of similar size to that of cigarettes, and comparable concentration of fine particlesEmit low levels of other toxins: formaldehyde, acetaldehyde, metalsCzogala et al, Nicotine and Tobacco Research 2013Fuoco et al, Environmental Pollution

2014Slide39

Role of surface contamination

Surface ContaminationNicotine, which combines with indoor substances such as ozone and nitrous oxide to make irritants and carcinogens (TSNAs), collects on surfaces from e-cigarette useGoniewicz and Lee, Nicotine and Tobacco Research 2014Slide40

Overall growth is impaired in newborn mice exposed to E-cigarette emissions

McGrath-Morrow, 2015 et al PLOS OneSlide42

Behavioral effects

Mice exposed to e-cigarette aerosol neonatally:More head dipsHigher levels of rearing activityIncreased markers of locomotor activityBut: increased time in new location in water mazeMarker of cognitive flexibility

Smith, et al PLOS One 2015Slide43

Cardiovascular effectsE cigarette aerosol induces reactive oxygen species and DNA damage in vitroNicotine and other components of e cigarette aerosol disrupted endothelial barrier function

E-cigarette use independent of combusted tobacco use is associated with a 42% higher risk of heart attackSlide44
