Explanation:

This appears to be a fill - in - the - blank question related to tobacco and smoking terms. Let's identify the correct terms for each blank:

1. For "the smoke from the burning end of a cigarette, pipe, or cigar", the term is Mainstream smoke (Wait, no, actually, the smoke from the burning end is "sidestream smoke". The smoke exhaled by the smoker is "mainstream smoke". Let's correct that. So:

• The smoke from the burning end of a cigarette, pipe, or cigar: Sidestream smoke
• The definition "second - hand smoke, is air that has been contaminated by tobacco smoke" is just a description of second - hand smoke, but if we are looking for the term for the air contaminated by tobacco smoke, it's "second - hand smoke" itself, but maybe the blank is for the term related to it. Wait, maybe the first blank: "Sidestream smoke" is the smoke from the burning end. The second blank: "Second - hand smoke" is the air contaminated by tobacco smoke. The third blank: "Mainstream smoke" is the smoke exhaled from the lungs of a smoker. The fourth blank: "Withdrawal" is the process that occurs in the body when nicotine, an addictive drug, is no longer used. The fifth blank: "Nicotine replacement therapy (NRT) product" (like nicotine gum, patch) is a product that delivers small amounts of nicotine into the user’s system while he/she is trying to give up the tobacco habit.

Let's list the correct terms for each blank:

1. Sidestream smoke: the smoke from the burning end of a cigarette, pipe, or cigar.
2. Second - hand smoke: second hand smoke, is air that has been contaminated by tobacco smoke.
3. Mainstream smoke: the smoke exhaled from the lungs of a smoker.
4. Withdrawal: the process that occurs in the body when nicotine, an addictive drug, is no longer used.
5. Nicotine replacement therapy product: a product that delivers small amounts of nicotine into the user’s system while he/she is trying to give up the tobacco habit.
