12 Signs Someone Is Hiding a Drug Addiction

Recognizing the signs of drug use and addiction can help you guide a loved one toward recovery. People with substance use disorders typically try to hide their symptoms, making it more challenging to notice when someone needs specialized care. However, you can recognize the warning signs more easily when you know what to look for. 

How to Tell if Someone Is Using Drugs

Understanding the immediate signs of drug use is important because consumption can quickly lead to a substance use disorder. Your loved one may be under the influence if you notice the following symptoms:

  • Impaired coordination
  • Abnormally sized pupils
  • Bloodshot eyes
  • Unusual breath or body odors
  • Slurred speech
  • Nausea or vomiting
  • Loss of muscle control
  • Increased agitation and energy
  • Diarrhea
  • Excessive yawning

Signs of Someone Using Drugs vs. Addiction

While obvious signs such as slurred speech and bloodshot eyes can indicate drug use, additional behavioral, mental, emotional and social signs may mean your loved one has developed a substance use disorder. Your loved one may hide their symptoms or avoid you while under the influence, so it's important to recognize signs of addiction.

12 Signs Someone Is Hiding a Drug Addiction

Look for the following signs of drug addiction to determine if your loved one needs help:

1. Physical Signs

In addition to physical intoxication symptoms, the following signs can indicate someone uses drugs regularly and has developed a substance use disorder:

  • Unexplained weight loss or gain
  • Tremors
  • Appetite changes
  • Sleep pattern changes
  • Gastrointestinal symptoms such as nausea, vomiting and diarrhea
  • Significantly declining physical appearance

2. Increased Tolerance

Drug use changes brain chemistry, and you may notice a loved one gradually needing more of a substance to feel the same sensations. Mental health and addiction professionals refer to this phenomenon as tolerance.

Drugs flood the brain's reward circuit with chemicals like dopamine and serotonin, producing intense positive emotions and pleasant feelings. As a person's substance use continues, their brain adjusts to the changes and reduces the reward circuit's response to the drug. The amount they started using may no longer cause the euphoric feelings they seek, motivating them to use higher amounts. 

Your loved one may have an addiction if you notice them using higher amounts of an illegal substance or misusing a prescription substance.

3. Mood and Personality Changes

A person with an addiction may experience sudden mood swings and unexplained personality changes. They may appear calm, happy or excited when they are under the influence and display intense irritability or angry outbursts when the drug wears off. If you notice your loved one acting differently than they previously did or exhibiting unexplained mood swings, they may have an addiction.

4. Unexplained Fear, Paranoia or Anxiety

A loved one with an addiction may also display unexplained fear, paranoia or anxiety. Anxiety is a common drug and alcohol withdrawal symptom, so your loved one may appear overly anxious when they are sober. A person may also appear overly fearful or jumpy while under the influence of a drug because some substances, such as hallucinogens, can cause temporary or long-term paranoia.

5. Hidden Drugs

A friend, partner or family member who uses drugs may hide them in the following places and objects:

  • Lipstick or lip gloss containers
  • The space between a highlighter's nub and the tip of its cap
  • Pen barrels
  • Gum and candy wrappers
  • Sanitary napkins
  • Dresser drawers
  • Video game consoles and remotes
  • Belt buckles
  • Unused shoes
  • Closet shelves and corners
  • Toilet tanks
  • Vents, outlet plates, light switches and ceiling tiles
  • Mattress holes and box springs
  • Picture frames and books
  • Water bottles and containers
  • Cars 
  • Outdoor bins and containers

While hidden drugs are the most significant indicator of addiction, you should also look for drug paraphernalia if you suspect a loved one needs intervention and help. Items such as lighters, needles, syringes, bongs, burnt spoons, broken glass, pipes, vape pen wrappers and cartridges and excessive amounts of eyewash solutions are often signs of addiction.

6. Relationship Complications

Drug use and substance use disorder can affect an individual's family and romantic relationships. Often, people experiencing substance use disorders prioritize drugs over the people they care about because of their intense physical and mental dependence. Your loved one may cause conflict with family members due to their mood and personality changes, potentially damaging connections with their nearest and dearest. They might also treat you or others differently than they used to, leading to strained relationships.

7. Sudden Social and Recreational Changes

In addition to relationship complications, someone in the throes of addiction may exhibit sudden changes in their social connections. They may abandon their favorite hobbies and relationships to spend time on unhealthy activities. They might lose friends due to their drug use or avoid specific people to hide their addiction. If your loved one suddenly shows little to no interest in activities they used to enjoy, they could be using their time to buy and use drugs.

8. Lack of Motivation or Unexplained Periods of Increased Energy

A person with addiction may display symptoms resembling depression or mania. Stimulants like cocaine and amphetamines can cause bursts of intense energy or physical activity, and a person may feel lethargic and unenthusiastic when one of these drugs wears off. In contrast, methamphetamines and marijuana can significantly lower motivation during and after use, causing a person to appear “spaced out” or excessively tired.

9. Behavioral Changes

You may notice the following behavioral changes if your loved one is hiding an addiction:

Frequent High-Risk Behavior and Legal Trouble

If your partner, friend or family member has a substance use disorder, they may engage in high-risk behaviors and find themselves in legal trouble. Driving under the influence and theft are typical consequences of addiction because substance use impairs judgment, and a person may steal money or valuable items to pay for drugs.

Suspicious or Secretive Behaviors

Another sign your loved one may have a substance use disorder is suspicious or secretive behavior. They might communicate less than usual, spend more time alone or provide little detail about their actions. It may be time to talk to your friend, partner or family member about their behavior if they seem excessively withdrawn or closed off.

10. Responsibility Neglect

Substance misuse causes people to prioritize drugs over every other facet of their lives, including their responsibilities. If your friend, partner or loved one has an addiction, they may gradually neglect obligations such as attending school, showing up to work regularly, paying their bills or caring for their children.

11. Unexplained Financial Challenges

Ignoring responsibilities and buying drugs can eventually lead to financial difficulties. A person living with addiction might ask to borrow large amounts of money or lose their job due to their erratic behavior. You may also notice a loved one struggling to pay their bills if they spend most of their money obtaining drugs.

12. Using Drugs Despite Negative Consequences

The compulsive desire to misuse substances may persist despite adverse repercussions like legal trouble, co-occurring mental illness, withdrawal symptoms, blackouts or damaged relationships. In this case, the person you care about most likely needs professional treatment to get sober and start recovering from their addiction.

How to Help a Loved One With an Addiction

How to Help a Loved One With an Addiction

You can't force a friend or family member to seek help for addiction, but you can offer encouragement and support with the following tips:

Plan an Intervention

An intervention is a chance for you to encourage your loved one to seek help for their addiction. Seek guidance from an addiction counselor or mental health professional and consider the following tips when planning an intervention:

  • Express feelings with care: Keep the conversation constructive by expressing feelings and concerns with care. Ask everyone involved to provide examples of how your loved one's addiction impacts them, and ask a neutral party, such as a counselor or therapist, to help keep the discussion focused.
  • Determine consequences: Determine specific consequences if your loved one refuses to seek help. For example, a consequence may be that they have to move out of your home or that they lose contact with certain family members.

Gather Resources

Gathering resources can help your loved one pursue help if they are willing. Gather the contact information for a treatment center so your friend or family member can seek professional support.

Maintain Boundaries

Boundaries are crucial because they help you avoid enabling behaviors. Enabling hinders your loved one's ability to face consequences and recognize that they need help, so it's important to keep the following tips in mind:

  • Avoid giving your loved one money, lying for them or making excuses for their actions while they are in active addiction.
  • Confront your friend or family member about unhealthy behaviors.
  • Follow through with expectations.
  • Let your loved one experience the natural consequences of their actions.

Maintaining boundaries is one of the most supportive actions you can take for a loved one with an addiction. Letting them face the consequences of their actions can encourage them to want help. They may lose their job, home or relationships, but these experiences may be the push they need to seek help.

Attend 12-Step Family Meetings

12-step groups such as Al-Anon Family Groups can help you learn more about setting healthy boundaries and avoiding enabling behaviors. You can also find support from other individuals with similar experiences.
