How to Tell If Someone Is Lying About Using Drugs

If you suspect a loved one is using drugs, it's important to understand the signs and symptoms. Unfortunately, individuals with substance-abuse problems are often secretive and lie about their behavior. You will need to pay less attention to their words and focus on their actions.

Instructions

• 1

  Watch for mood changes, which comprise one of the most obvious signs of drug use. A person may go from being extremely happy to irritable and angry. Chart the mood changes to look for regular patterns.

• 2

  Be on the lookout for disappearing money. People who are using drugs often spend money quickly without any explanation. If you share a bank account with this person, you may notice large cash withdrawals.

• 3

  Notice irresponsible behavior. Drug use can make a previously responsible person miss work or school without explanation. The person may lie and make excuses for the frequent absences.

• 4

  Heed physical changes. Drugs take a toll on the body. Depending on which substances are being abused, you may notice unexplained weight loss. Some drugs can cause more obvious signs, such as missing teeth in a previously healthy person.

• 5

  Observe heightened aggression. Many substances alter chemicals in the brain, which can increase aggression. This change can result in irritability and physical violence.
