Mainstream smoke is smoke that is inhaled and then exhaled by the smoker. Sidestream smoke is the smoke that comes from the burning end of the cigarette, pipe or cigar. Breathing either mainstream or sidestream tobacco smoke is called passive smoking. Nicotine and other chemicals that can harm nonsmokers are present in mainstream and sidestream smoke. Sidestream smoke is more harmful to nonsmokers than mainstream smoke, because sidestream smoke has not had any tars or other chemicals removed by the smoker's lungs.
Groups create smoking situations.
Ask students to imagine situations in which they might want to request a smoker to stop smoking but would feel uncomfortable doing so and write down two situations. Divide class into small groups. Ask groups to discuss each situation and the reasons students might feel uncomfortable asking the smoker to stop. Discuss listening skills. Ask students to brainstorm qualities of a good listener and write their responses on the board.
