Introduction:
Nicotine withdrawal effects such as irritability, anxiety, poor concentration, memory impairment, and insomnia can occur after cessation of chronic nicotine use. In addition, exposure to nicotine in adolescence may have adverse affects on the adolescent brain, with postulated risks including impaired memory and attention, increased risk of substance abuse, and addiction and poor academic performance. Electronic cigarettes (e-cigarettes) are a relatively new form of nicotine delivery device and the prevalence of their use is rapidly growing in many countries.
