Final answer:
The warning sign of drug abuse more than drug addiction is an inability to focus on your schoolwork, employment, or home responsibilities.
Step-by-step explanation:
The warning sign of drug abuse more than drug addiction is an inability to focus on your schoolwork, employment, or home responsibilities. This means that someone who is abusing drugs might struggle to concentrate and fulfill their duties in these aspects of their life.
In contrast, multiple unsuccessful attempts to cut down drug use or the need for increased amounts of the drug to experience the same high is more indicative of addiction, where there is a compulsive use of the substance and potential physiological dependence involved.
