so that it does not worry. 



2. Tobacco is a narcotic which depends upon a poison 



called nicotine for its effects. 



3. Tobacco is smoked, chewed, and snuffed up the nose. 



In all three ways, nicotine enters the body. 



4. Tobacco not only harms those who use it, but its use is 



unpleasant to those who do not use it. 



5. Opium is a narcotic used to produce sleep and to quiet

 tinued produces death.

7. A person must be kept awake when he is poisoned by 



a narcotic.
