In some people, using any amount of tobacco can quickly lead to nicotine dependence. Signs that you may be addicted include:
You can't stop smoking. You've made one or more serious, but unsuccessful, attempts to stop.
You experience withdrawal symptoms when you try to stop. Your attempts at stopping have caused physical and mood-related signs and symptoms, such as strong cravings, anxiety, irritability, restlessness, difficulty concentrating, depressed mood, frustration or anger, increased hunger, insomnia, and constipation or diarrhea.
You keep smoking despite health problems. Even though you've developed problems with your lungs or your heart, you haven't stopped or can't stop.
You give up social or recreational activities in order to smoke. You may stop going to smoke-free restaurants or stop socializing with certain family members or friends because you can't smoke in these locations or situations.
