Beginning of waterpipe epidemic268 WP smokers in cafés (Aleppo)

Rastam, Maziak et al. Estimating the beginning of the waterpipe epidemic in Syria. BMC Pub Health 2004.

Factors behind the current waterpipe pandemic

1. Introduction of Maassel in the early 1990s.

2. The internet & other social and transnational media

3. The reduced-harm perception, “the water filtering” effect

4. The allure of waterpipe and thriving café culture.

5. Lack of effective policies (e.g. FCTC).Maziak W. The Global Epidemic of Waterpipe Smoking. Addictive Behaviors 2011.

1. Maassel?1. Industrialized and commercialized

the product, increasing availability

and variety

2. Appealed to youth through product

variety and flavors

3. Made the smoke milder and

smoother

4. Allowed the mass marketing and

sales through the internet

5. Simplified the preparation process

Maziak W. The Global Epidemic of Waterpipe Smoking. Addictive Behaviors 2011.

2 .The internet & other social media

Websites may play a role in enhancing or propagating misinformation related to hookah tobacco smoking. The promotional materials …de-emphasize age limits, health warnings, and even that tobacco is involved in hookah smoking. Primack et al., 2012.

3. Reduced harm perception

Qualitative study of 15 WP and 15 Cig smokers;

(Hammal et al, 2008) “I do not worry about narghile. I

do not feel it is harmful. It is not more than

entertainment. We have not heard about anyone who

had a health problem because of the narghile”

Hammal F, Mock J, Ward KD, Eissenberg T, Maziak W. A pleasure among friends. Tobacco Control 2008.

4. Allure of waterpipe

Asfar T, Ward KD, Eissenberg T, Maziak W. BMC Pub Health 2005;5(1):19.Smith-Simone, Maziak, Ward, and Eissenberg. Nicotine & Tob Research, 2008, 10: 393–398.

1. I enjoy the taste, smell, smoothness of smoke

2. It’s a good way to socialize with friends

3. It helps me to feel relaxed

4. I like the social ambience

5. It helps me to feel less stressed

6. It’s something to do when I feel bored

7. I like trying things that are new, different, or “hip”

9. It helps me not smoke cigarettes

5 .Lack of effective policies

Smoke narghile mostly at home

Usually share the same narghile with others

Once addicted on nicotine, young people may go for Cig because of easier access compared to WP (gateway hypothesis)

Main epidemiological trends for WP

• Common among youth all over the world and increasing

• More intermittent use than daily• Educated and affluent (higher SES)• Male predominance, not consistent across

populations and age groups.• Associates with cigarette smoking at early ages

and can lead to cigarette smoking.

Summary • Waterpipe smoking is widespread and increasing all

over the world.• It is more widespread among the young, educated

and affluent • Gender differences in waterpipe smoking tend to

vary by region, but girls and women in the EMR are increasingly taking up this tobacco use method

• Surveillance systems that inquire specifically about the waterpipe and are adapted to its use patterns are needed to monitor the epidemic and groups more at risk of waterpipe smoking
