I've known many people who have lived and worked with smokers all their life without becoming addicted. There are both mental and physical components to tobacco addiction and without both you probably wouldn't be attracted to smoking. Liking the smell and the atmosphere would be part of the mental side but not a physical addiction.
We know that smoking is catastrophic for both smokers and second smokers. One can even become addictive if he/she does not smoke. So, its better to quit this habit. An addictive person can make use of legal herbal incense. These have same effect but are harmless. For such incense one can visit https://www.legalherbalonline.com/store
