or mental functioning is a drug. Many people mistaken believe theS1.______

The phrase "substance abuse" is often used instead of "drug

abusive" to make clear that substances such as alcohol and tobaccoS5.______

can be just as harmfully used as heroin and cocaine. We live in a societyS6.______

which the medicinal and social use of substances is pervasive: anS7.______

aspirin to quite a headache, some wine to be sociable, coffee to getS8.______

going in the morning, a cigarette or the nervous. When do these sociallyS9.______

acceptable and apparently constructive use of a substance become

or substance dependence.
