INTRODUCTION

THE GLOBAL IMPACT OF SMOKING ON HEALTH

• Smoking is the major preventable cause of disease in the world.

• About 80 percent of these people live in low and middle-income countries.

• Tobacco used– 1.3 billion smokers (World Bank, 2003)

• Tobacco kills– 4 million deaths per year (CDC, 2000)

3

Every day , THOUSANDS of young people around the world are trying their first cigarette and 80,000 – 100,000 are becoming regular smokers often precipitating a lifetime of addiction and untimely death.

Fig 13:“Youth should be inculcated in a “Calture without Tobacco”- Chairman ASHIQSW 2000

BY THE YEAR 2020• WHO estimated that if the current worldwide

smoking patterns were to persist then 10 million deaths will occur per year from tobacco consumption by 2020.

• Tobacco will become the leading cause of death and disability thus causing more deaths world-wide than HIV, TB, maternal mortality, MVA, suicide and homicide (WHO, 1999)

World No Tobacco Day Geneva, 30 May 2006

"Tobacco: deadly in any form or disguise," focusing on the fact that all tobacco products are addictive, harmful and can cause death, regardless of the form, packaging, or name under which they are presented to the public”.

Recommendations

• To strengthen existing anti-smoking programs to maintain low smoking prevalence

• Universities can develop intensive and updated anti-smoking programs at the Web pages and also deliver messages through their radio stations
