• Chemicals in liquid absorbed through lung, throat and oral tissues
• “E-Juice” contains:
– Propylene Glycol
– Vegetable Glycerin
– Flavour additives

• JUUL: slim, easily concealable, non-refillable cartridge system
– Nic salts
• Other brands: SMOK, Vype, Logic, Aspire, Suoirin

E-Cigarette Epidemic in
Adolescents
• The 2016-17 Canadian Student Tobacco, Alcohol and Drugs Survey: the prevalence of ever trying an e-cigarette increased to 23% (approximately 470,000 students). This is pre-legalization of nicotine containing e-cigs.
• Frequency of use is increasing amongst users.
• Potential for delivery of high level of nicotine – tasteless and odourless with even brief experimentation leading to dependency.

2018 BC Adolescent Health Survey
Overall decrease in youth who had smoked tobacco: 21% in 2013 to 18%
in 2018
Significant increase in e-cig use for students who had smoked: 16% in
2013 to 64% in 2018
This means, 21% of all BCstudents are vaping with nicotine and
19% without nicotine.
Among youth who had never smoked 11% vaped with nicotine, and 13%
without nicotine in the past 30 days.

Youth vaping
Reasons for use
• The flavours are appealing and the devices look cool
• It makes them feel rebellious: they vape in places that are not allowed as it is easy to conceal
• Their friends are vaping, it helps them fit in
• Curiosity and/or boredom
• They consider the vapour to be less harmful compared to tobacco smoke
• They like the “hit” they get from nicotine

Health Concerns:
Nicotine
• Teens are most at risk due to
developing brains – nicotine changes the way synapses are
formed, that can last a life time.
• Brain risks: decreased attention, impulse control, decision making, cognitive performance, depression, nicotine withdrawal
• Respiratory symptoms: chronic cough, bronchitis, asthma, serious lung disease.
• Impacts will be in all organs/systems with nicotinic receptors.
• Nicotine dependence - No data on how to treat but if analogous to tobacco a struggle with high relapse rate
• Increased risk to use other substances such as alcohol and cannabis.
Page 8
Health Concerns: Other
• Vaping liquids: typically include glycerol, flavours,
propylene glycol. Long term health effects of
inhaling these substances is unknown.
• Vaping (heating), causes reactions and create new chemicals such as formaldehyde and acetaldehyde.
• Vapour: heavy metals (chromium, nickel and lead), VOC, particulate matter.
• Flavours: meant to be eaten not inhaled so we do not know what impact they will have short and long term
• Dental Health: excess bacteria, dry mouth, inflamed gums, cell death due to DNA damage (periodontal disease, bone loss, tooth loss, tooth decay).

Principle of Toxicology
“The dose and the route make the poison”
no long term vaping toxicological/safety studies have been done in humans
Page 10
Tobacco Cigarette Initiation
• “E-cigarette use was strongly associated with cigarette smoking behaviour, including smoking initiation at follow-up.”
Hammond D, Reid J, Cole A, Leatherdale S, Electronic cigarette use and smoking initiation among youth: a longitudinal cohort study, CMAJ October 30, 2017 189 (43) E1328-E1336
“e-cigarette use is
associated with
increased risk for
cigarette initiation and
use, particularly among low-risk youths”
JAMA, 2019

Vaping is not for youth or
for non-smokers
• We need to stop the message that vaping is a safer alternative.
• At the moment all we can say is e-cigs are a less harmful alternative to those adults with a nicotine addiction.
Absence of evidence of harm is not evidence of absence of harm.

Big Tobacco
• Philip Morris bought 35% of JUUL at 13 Billion
• Big tobacco is duping a generation into a life long addiction
• Big Tobacco using advertising/marketing techniques that converted millions to smokers

• Federal TVPA:
– “Legalized” sale of vaping products to adults in 2018 (Bill S-5)
– Some vaping ads/promotions permitted unless aimed at youth or lifestyle advertising
– Flavour marketing restrictions
– New Federal rules pending:• Prohibitions on advertising/ marketing
• Mandatory health warnings on vaping product packaging
• Nicotine level limits
– Additional rules likely in future
The Law:
Federal
Page 17
• B.C. TVPCA/TVPCR:
– Access restricted to 19+
– No ads/promotions in-store
– No vaping on school property (TVPCA s.2.2(3.1))
• Nov. 15, 2019: Provincial Government announced 10-point plan to tackle youth vaping, including:– Restrictions on access to flavours
– Advertising and labelling restrictions
– 20% tax on vapour products
– Toolkit for schools
The Law: Provincial
Page 18
• EDUCATION of risks of vaping from Board level to boards, schools, students, parents
– Incorporate vaping education into regularly scheduled school meetings
– Circulate vaping information to students and parents
• Develop consistent policies to deal with vaping on school grounds– Clearly communicate policy and
consequences of violations to all school employees, students, parents and visitors
– Visible, unambiguous signage
SCHOOLS
&
SCHOOL BOARDS
Page 19
• Learn about the risks of vaping and share that knowledge and those resources with your children
• Don’t underestimate or downplay the power of nicotine addiction
• Be patient and listen
• If you smoke or vape, talk to you children about it and think about quitting yourself. If you and your child are both addicted to nicotine, talk about quitting together
• Don’t buy your children vapes
• Manage your child’s expectations about quitting
WHAT CAN PARENTS
DO?
Page 20
What to do for youth with a
nicotine problem
• Prevention, prevention, prevention– Effort and attention into the younger grades and those not
vaping important
– Emphasis on resiliency and critical thinking skills
• Interventions:– Quitnow offering phone and live chat to youth 15+
– Motivational Interviewing and client-centred
– Some therapies for tobacco not applicable to nicotine addiction secondary to vaping:• NRT (gum, patch, lozenges, inhaler)
• Prescription drugs: Champix or Zyban

Summary
1. Vaping amongst youth is a rapidly growing phenomenon
2. Vaping is not harmless. Long term health risks will become clearer with time.
3. Addiction to nicotine may have a dramatic effect on public health. We do not have any evidence based interventions for youth that are addicted.
4. “Big Tobacco” is the main promoter and seller
5. We need to apply the knowledge and regulatory tools learnt with tobacco but we need to move faster
