Dependence

There are 2 forms of tobacco dependence: physical dependence and psychological dependence (also known as behavioural dependence).

Physical dependence

Physical dependence is linked to the nicotine contained in tobacco. Nicotine is what gets the smoker addicted. With every puff of a cigarette, nicotine enters the bloodstream and affects certain parts of the brain. Smokers gradually get used to having a dose of nicotine in their body. If the nicotine level drops, they begin to feel the need to smoke and this becomes overwhelming. This lack of nicotine - this actual physical need - explains why people find it difficult when they try to give up smoking. This state of dependence is also the main reason why people are often unsuccessful when they try to quit.

Psychological or behavioural dependence

Psychological or behavioural dependence is linked to lifestyle habits. Over time, smoking becomes associated with certain life situations: after meals, with alcohol, in the car, on the phone, when stressed, to relax, etc. Smoking becomes something of a ritual. The cigarette triggers the smoking reflex. The feelings of wellbeing experienced while smoking maintain this psychological dependence. Stopping smoking also means changing your lifestyle habits to break these reflexes.
