Generally, the people who enjoy smoking the most are most affected by nicotine. and their bides metabolize nicotine, so they want more; thus the addiction. Most people who do not become addicted to nicotine are not affected by it, but there are some who enjoy it and do not become addicted. The physically damaging effects of nicotine are minor for most people, and people who metabolize it quickly usually repair the damage from smoking, which is why one a small percentage of long term smokers have major health effects. Conversely, the people who do not become addicted do not repair the damage from smoking as quickly, and the damage can be cumulative, so the non-addicts are more likely to have major health effects.
When discussing nicotine, one should keep in mind that it acts strongly in the brain. Addiction to nicotine is related closely with its effect as a neuro-transmitter.
