It's not addictive. That's a psyop
Is smoking addictive?
National Institute of Drug Abuse.
Yes. Most smokers use tobacco regularly because they are addicted to nicotine. Addiction is characterized by compulsive drug-seeking and use, even in the face of negative health consequences. The majority of smokers would like to stop smoking, and each year about half try to quit permanently. Yet, only about 6 percent of smokers are able to quit in a given year.25 Most smokers will need to make multiple attempts before they are able to quit permanently.22 Medications including varenicline, and some antidepressants (e.g. bupropion), and nicotine-replacement therapy, can help in many cases (see "What are treatments for tobacco dependence?").26
