3 groups:

(1)Smokers (who may also be passive smokers at the same time)(2)Passive smokers are non-smokers themselves but are exposed to tobacco smoke at home or in the workplace.(3) Non-smokers are not exposed to tobacco smoke either at home or at workplace.

According to a study from Basel, Switzerland :

•Workplaces where smoking is permitted make 34% to 46% contribution to passive 34% to 46% contribution to passive smokingsmoking;

•Heavily TS-exposed housewives potentially smoke 18 cigarette smoke 18 cigarette equivalents/yearequivalents/year;

•Workers who are heavily exposed to TS in the workplace and at home potentially smoke 61 cigarette equivalents/yearsmoke 61 cigarette equivalents/year;

Levels of indoor air pollution in 2,531 locations in 32 countries.

Global Air Monitoring Study

TSI SidePak AM510 Personal Aerosol Monitor was used to measure PM2.5

On average, smoke-free laws result in an 8-fold reduction in the levels of indoor air pollution

Quickly reduce air pollution

In bars and restaurant in Ireland after the smoking ban:

Reduce by 83% level of fine particulates Reduce by 83% nicotine contentsReduce CO by 45%

Smoking section does not protect non-smokers ???

NEITHER DOES THIS?

ANALOGY

ASHRAE Statement, 2005

• “At present, the only means of effectively eliminating the health risk associated with indoor exposure is to ban smoking activity.”

• “Because of AHSRAE’s mission to act for the benefit of the public, it encourages elimination of smoking in the indoor environment as the optimal way to minimize ETS exposure.”

- American Society of Heating, Refrigerating, and Air Conditioning Engineers, from its 2005 position document on environmental tobacco smoke (SHS)

There is NO SAFE LEVEL of exposure to tobacco smoke and scientists have

concluded that elimination of the source of the smoke is the ONLY scientifically-

proven way to protect the health of nonsmokers.

This means 100% smoke-free environments indoors.

• Ireland: reduce 16.7% respiratory symptoms after one year

• California: reduce 59% respiratory symptoms after three months

• In Colorado USA and Piedmont Italy: reduce 20% hospitals admission due to heart attacks after smoking ban

Improve health of workers and public

Reduce consumption and increase quit rate

• World Bank: SFE reduce consumption by 4-10%• Summary of studies conducted in Australia, USA,

Canada, Germany: – Reduce 3.1 cigarettes/day– Increase quitting by 3.8%.

SFE reduce up-take by children

• On average implementation of SFE help: – Reduce taking up by 17% – Reduce youth tobacco

consumption by 50%• Motivate implementation of

smoke-free homes: – Help reduce youth taking up

by 1/4

Other benefits of SFE

1. Increase productivity,

2. Reduce medical costs

3. Reduce insurance costs,

4. Reduce building maintenance costs

5. Improve image of the workplaces

Support for comprehensive smoking bans in bars and restaurants after implementation

Dr. Gro Harlem Brundtland,Director-General, World Health Organisation1998-2003

"If we do not act decisively, a hundred years from now our grandchildren and their children will look back and seriously question how people claiming to be committed to public health and social justice allowed the tobacco epidemic to unfold unchecked."

4 out of every 5 non-smokers support smoke free laws in work place and restorans

3 out of 5 smokers also support such law

From Malaysia’s ITC Study

• Davao City (Mindanao), Philipines

• Luang Prabang, Laos PDR

Smoke-free in Southeast Asia

• This effort is showing the Penang State Government’s obligation to protect the health of its people, both smokers and non-smokers.

THANK YOU FOR NOT SMOKING!!
