smoked cigarettes before (this was for people ages 18–34). This study could support the gateway drug theory. Cessation Smoking cessation, referred to as "quitting", is the action leading towards abstinence of tobacco smoking. Methods of "quitting" include advice from physicians or social workers, cold turkey, nicotine replacement therapy, contingent vouchers, antidepressants, hypnosis, self-help (mindfulness meditation), and support groups. In the United States, about 70% of smokers would like to quit smoking, and 50% report having made an attempt to do so in the past year. Without support, 1% of smokers will successfully quit smoking each year. Physician advice to quit smoking increases the rate to 3% per year. Adding first‐line smoking cessation medications (and some behavioral help), increased quit rates to around 20% of smokers in a year. In recent years, especially in Canada and the United Kingdom, many smokers have switched to use electronic cigarettes in order to quit smoking tobacco.
