What to Do if Someone You Love is Using Drugs

If someone you love is using drugs, taking thoughtful, supportive, and safe action is essential. The following are things to consider when approaching a loved one about addiction.

• Educate Yourself: Learn about the substance they may be using, its effects, and potential risks. Understanding addiction helps you approach the situation with knowledge rather than judgment.
• Approach with Care and Empathy: Choose a private, calm moment to talk. Use “I” statements like “I’m worried about you” instead of accusatory language. Listen actively and avoid interrupting or criticizing.
• Express Concern, Not Blame: Focus on the impact on their health and well-being rather than punishing or shaming them. Make it clear that your concern comes from care and love.
• Encourage Professional Help: Suggest treatment options such as counseling, rehab centers, or an Employee Assistance Program. Offer to help research programs, schedule appointments, or accompany them if they are open to support.
• Set Boundaries: Protect yourself emotionally and physically. Clearly communicate what behaviors you cannot tolerate while still expressing support for their recovery.
• Avoid Enabling: Don’t cover up, lie, or provide money that could support drug use. Enabling behavior can unintentionally prolong addiction.
• Support Recovery: Celebrate small steps toward change, encourage healthy habits, and be patient. Recovery is often a long process with setbacks, and consistent support matters.
• Seek Support for Yourself: Consider attending support groups for families of people with addiction, like Al-Anon or Nar-Anon, or seeking counseling. Supporting someone with addiction can be emotionally challenging, and you need guidance and self-care.

When is it Bad Enough to Confront Someone About Addiction?

Confronting someone about addiction should be done carefully and usually when certain signs indicate that the situation is serious enough to warrant action. The following are signs the addiction may be bad enough.

• Safety Concerns: If the person’s drug use is putting them or others at risk, such as driving under the influence, engaging in risky behavior, or threatening harm, immediate action is needed.
• Health and Physical Symptoms: Severe or worsening physical signs like frequent nosebleeds, track marks, rapid weight changes, or signs of overdose indicate that professional intervention is necessary.
• Functional Impairment: When drug use begins to significantly affect work, school, finances, or relationships, it shows the addiction is interfering with daily life.
• Legal or Financial Problems: Repeated arrests, theft, or financial instability caused by substance use signal that the problem is escalating and requires attention.
• Denial or Refusal of Help: If subtle attempts to discuss concerns have failed and the person continues to deny or hide their drug use, a structured and compassionate confrontation may be necessary.
• Emotional and Behavioral Changes: Persistent mood swings, aggression, withdrawal from loved ones, or changes in personality can signal that drug use is severe enough to intervene.
• Repeated Relapse or Escalation: If the person has previously tried to quit or cut back and keeps relapsing, it may be time for a direct and supportive conversation about professional help.

How They Might React & How to Respond

The following are common reactions and potential responses in regards to the situation.

“I don’t have a problem”
Response: Stay calm and use observations instead of accusations. Say something like, “I’ve noticed changes in your behavior and health, and I’m concerned about your well-being.” Focus on care, not blame.

“I can quit anytime I want”
Response: Acknowledge their confidence but gently highlight patterns. For example, “It seems like you’ve tried to cut back before and had a hard time. I want to help you find support if you’re ready.”

“It’s not a big deal”
Response: Validate their feelings but explain the potential risks. “I understand it may feel minor, but I’m worried about your health, relationships, and future. Let’s look at ways to get help together.”

“Leave me alone”
Response: Respect their space but keep lines of communication open. “I hear you. I’m here when you’re ready to talk. I care about you and want to support you.”

“Everyone does it”
Response: Gently challenge normalization and focus on consequences. “Even if others do it, it can still harm your health, job, and relationships. I want to help you stay safe.”

“I’m fine / I don’t need help”
Response: Emphasize concern and availability of support. “I know you feel okay now, but I’m worried about the risks. When you’re ready, I can help you find professional support.”

“You don’t understand”
Response: Listen actively and show empathy. “You’re right, I may not fully understand. I want to listen and support you in finding help that works for you.”

Recognizing the signs of drug use early can be a critical step in helping someone get the support they need. Behavioral changes, physical symptoms, emotional shifts, and the presence of drug paraphernalia are all important indicators to watch for, especially when they appear in combination or persist over time. While noticing these signs can be concerning, approaching the situation with care, empathy, and patience can make a meaningful difference. By staying informed, offering support, and encouraging professional treatment when necessary, friends and family can play a vital role in guiding a loved one toward recovery and a healthier future.
