Nicotine by itself is actually very safe and probably less addictive than coffee. Its when they add MAO inhibitors to cigarettes along with other chemicals that makes it addictive.
Vaping, as someone else mentioned, has glycine which some evidence shows can be damaging to lungs. Also some vaping devices can heat up to very high temperatures and can potentially allow chemical from the apparatus to leach in. Some get so hot they explode. A good amount of people had their face severely injured and some even died from their vape exploding.
