Both cigarettes and e-cigarettes contain nicotine, the same toxic and highly addictive stimulant contained in traditional cigarettes.
Nicotine makes you crave a smoke; if you ignore the craving, you may experience withdrawal symptoms, such as irritability, restlessness, hunger, difficulty concentrating, sleep disruption and depression.
Nicotine also raises your blood pressure and spikes your adrenaline, both of which increase your heart rate and risk of a heart attack.
E-cigarettes were marketed as a way to quit smoking, but evidence shows that rather than discontinuing your addiction, vaping can create the opposite effect by increasing the amount of nicotine you consume.
