1997 – Canadian Tobacco Act
Advertisements Tobacco companies may:
Only promote their products in publications delivered directly to an adult or in places where
young people aren‘t permitted by law, such as bars or taverns.
Only highlight actual brand characteristics, rather than by "lifestyle" advertising that attempts to
portray the product to consumers in a flattering light.
Advertisements Tobacco companies may NOT:
Attempt to convince young people of the desirability of their product by associating it with
glamour, recreation, excitement, vitality, risk, daring, or sexuality.
Depict any tobacco product, or its package or brand — or even any imagery that might evoke a
product or brand.
Sponsor youth-oriented activities or events.
Include the name of a tobacco product or manufacturer as part of the name of a permanent sports
or cultural facility.
Events (e.g., sporting) supported by the tobacco industry before April 1997 could continue
receiving such support for the five-year transition period. By the end of the five-year transition
period (October 2003), tobacco sponsorship promotions and the display of tobacco brand
elements in or on permanent facilities would be prohibited altogether.
Retailers are permitted to display branded tobacco products and accessories, as well as signs that
indicate the availability of tobacco products and their prices.

Who Smokes: Canadian Data
-not much of a gender component, men smoke more than women but not big difference

education that decreases smoking?
delay of gratification (marshmallows) – people who seek educations are more future
-certain vocations where only smokers go on break, contagious to smoke

The most important toxic compounds in tobacco smoke (Carbon Monoxide) - CO
-an odorless, colourless, tasteless toxic gas
-attaches itself to hemoglobin better than oxygen
-Produces a slow asphyxiation of the body
-a cause of cardiovascular diseases
The most important toxic compounds in tobacco smoke – TAR
-sticky, adheres to cells in the lungs and airways
-impairs ciliary escalator
-permits carcinogenic compounds to settle on pulmonary tissue; origin of metastatic cancers
-TRACHEA tube that connects airway to lungs, cilia, when you breathe in something cilia
breathes it in and sweeps it out. Tars bind to the cilia and destroys them. SO now nothing can
sweep out the particles, they then go to alveoli sacs in the lungs which creates cancer. Once in
the lungs it goes into the blood stream, gets stuck somewhere else, Metastatic Cancer.
-MJ smoke contains same basic tar and CO chemicals, but it does contain chemicals that you
breathe in that help prevent cancers
The most important toxic compounds in tobacco smoke NICOTINE
-toxic, dependence-producing psychoactive drug found exclusively in tobacco
-stimulus CNS receptors (nicotinic) sensitive to acetylcholine
-inhibits activity in the GI tract
-passes blood brain and blood placental barrier in about 5-8sec
-widely used as an insecticide
-double glove before going near a bottle of nicotine
-Nicotine makes effects of other drugs more powerful There are some other things in tobacco that
What government uses Polonium?
-cooked from inside out
DO filtered cigarettes have fewer toxins?
Filtered cigs have a filter to remove toxins; the filter also decreases the tar (flavour) for the user
To compensate, cigarette manufacturers increased the tar in their cigarettes, effectively negating
the purpose of the filter
The smoke passively inhaled by a non smoker is thus more toxic from a filtered cigarette
Are hookahs safer?
Tobacco is placed inside the head, where it is commonly covered by tinfoil and coal is placed on
top to burn the tobacco
The added coal contributes to a number of added toxins to the tobacco
Water is placed in the bottom portion of the hookah where it is believed to capture toxic waste
Sessions tend to last up to 20-25 minutes with a person puffing between 50-100times ( a cigarette
smoker on average smokes for 5-7mins puffing between 10-20puffs)
A single water pipe session results in the same carbon monoxide and tar intake
