Cigarettes contain over 4,000 chemicals including arsenic, paint stripper and at least 60 carcinogens.
Smoking adversely affects every organ system in the body.
Most smoking related deaths are from lung and heart diseases.
Nicotine acts on cholinergic and mesolimbic (dopaminergic) central nervous system pathways, (it releases “feel good” chemicals).
Repeat exposure to nicotine causes neuro-adaptation often resulting in tolerance; this leads to more smoking for the same pleasurable effect and to avoid withdrawal- basically smoking cigarettes affects you the same way as heroin.
Health benefits start within 24 hours of stopping smoking.
