PSYCHOLOGICAL DRUG ABUSE EFFECTS
One of the primary effects of drug abuse can be found within the definition of drug abuseitself: an increasing, intense desire to use the drug above all else. Drug craving can shift a person's entire mental focus to obtaining the drug. Side effects of drug abuse then include preoccupation with where to get the drug, how to get money for the drug, and where and when the drug can be used.
Psychological drug abuse effects commonly include changes in mood. A person may be anxious, thinking about when they can next use the drug, or depressed due to drug side effects.
Other psychological drug abuse side effects include:
Aggressiveness or irritability Selfishness Hopelessness Lack of pleasure from previously enjoyed activities Pressuring others into doing drugs
