Smoking particularly when initiated at a young age leads to nicotine

Nepal, 15000 people every year die due to tobacco consumption and nicotine
dependence. Nepal has high mortality rates as a result of high smoking rates
among adolescents population(Sreeramareddy et

Nicotine is a key for dependence, including compulsive use, despite the
repeated attempts to quits smoking. Cigarettes, unlike other chewed tobacco,
rapidly enable nicotine to reach the human brain within seconds of
inhalation. In 2000, it was estimated
that tobacco killed approximately 4 million people worldwide – 2 million each
in developed and developing countries. By 2030, it is expected to be 1 in 6 or
10 million deaths each year and 70 per cent of them would occur in developing
countries. By 2030 tobacco is assumed to become the number one killer. (MOHP, 2012). Nicotine dependence
causes a main role in sustaining smoking among adolescents which increase from
experimental patterns to regular use of smoking(Rojas
et al., 1998).
