How to Tell If Someone Has a Substance Abuse Problem

Without catching someone in the act of using a controlled substance, there are signs that can suggest possible use. These signs can be physical and can vary depending on the substance being abused. Because physical symptoms can be associated with other issues, such as stress, it is also important to note significant changes in someone's behavior, appearance, personality or attitude.

  Notice if there are distinct changes in the person's daily life. Is there is a significant increase or decrease in appetite, new groups of friends, lying, loss of interest in hobbies, lack of motivation or frequent borrowing of money? Another obvious sign is the presence of drug paraphernalia or empty bottles.

• 2

  Look for changes in the person's physical appearance. Take note of any sudden increase or decrease in weight or a change in overall appearance and hygiene. Other physical symptoms might include poor coordination, red and watery eyes, puffiness and changes in facial color, needle marks, uncontrollable shaking, and frequent illness.

  Notice changes in personality. Outbursts of anger, delusions of grandeur, paranoia, moodiness, secretive behavior and oversensitivity are all signs of possible substance abuse. Periodic giggling and silliness can also indicate that certain substances are being abused.
