A friend and co-worker has expressed concern about her drug use becoming abusive and requested you observe her habits. Which of the following are warning signs that you can show her to encourage the desire to end the abuse?
a. Improved grooming, consistent moods, and extreme changes in appetite
b. Need for large amounts of money, increased physical activity, and hunger
c. Unusual smell on clothes or breath, bloodshot eyes, and paranoid behavior
d. Intermittent nosebleeds, sport-specific training, and increased effort at school

The correct answer is c. Unusual smell on clothes or breath, bloodshot eyes, and paranoid behavior.

Explanation:

From the description, we assume the friend is an occasional drug user. However, she seems to have noticed her use is increasing, and is worried about exaggerating. Occasional users may show up with bloodshot eyes and unusual smell on clothes or breath. Still, there are several signs that show a person is becoming or has become addicted. One of those is paranoid behavior. If the friend begins to show paranoia, it is best that she stop her drug use immediately and seek help.
