What you might be experiencing
Addiction rarely announces itself. What you're more likely to notice is a slow accumulation of things that feel wrong — a loved one who seems more distant, more defensive, less like themselves. The changes can be easy to explain away individually: stress at work, a rough season, a new crowd. It's the pattern that starts to tell a different story.
Behaviorally, signs can include lying about whereabouts, secrecy around their phone or finances, neglecting work or school, dropping hobbies they used to care about, or spending more time with people who use substances. You might find paraphernalia, notice money or valuables going missing, or hear repeated requests to borrow money without clear explanation. Physical signs vary depending on the substance involved, but can include changes in sleep or appetite, bloodshot eyes, noticeable weight changes, poor hygiene, or frequent unexplained illness.
Emotionally, you may feel like you're living with someone whose mood is unpredictable — irritable one moment, withdrawn the next, or strangely different when they've been using. You might also notice anxiety, depression, or a creeping sense that the person you knew has become harder to reach. That feeling is worth trusting, not minimizing.
What can help
When you're concerned about someone's relationship with substances, focusing on patterns rather than isolated incidents gives you clearer ground to stand on. Keeping informal notes — dates, specific behaviors, what you observed — can help you see whether problems are recurring and give you concrete examples to share if you decide to have a conversation.
If you choose to speak with them, timing and tone matter. Avoid bringing it up while they are intoxicated or in the middle of a conflict. A calmer moment, with specific and non-accusatory language, is more likely to be heard: naming what you've observed rather than what you've concluded keeps the door open. Learning about addiction as a health condition rather than a moral failure can also shift how you approach the conversation — and how they receive it.
Your own wellbeing matters here too, and it often gets overlooked. Family support groups — including Al-Anon, Nar-Anon, and similar programs — are designed specifically for people in your position and can offer community, perspective, and practical guidance. A therapist who works with families affected by addiction can also help you figure out where healthy support ends and enabling begins. You cannot control whether someone enters recovery, but you can make choices that protect your own health and stop reinforcing harmful patterns.
When to reach out
Reaching out for help — for yourself or for someone you love — is not a last resort. It is a reasonable response to a serious situation, and doing it earlier rather than later usually leads to better outcomes for everyone involved.
Professional guidance is warranted when you notice escalating use despite clear consequences, signs of withdrawal (which can be medically dangerous depending on the substance), overdose risk, episodes of violence or threats, or a significant decline in someone's mental health. A primary care physician, addiction specialist, or mental health professional can help assess what's happening and what level of care makes sense.
If someone is in immediate danger — unconscious, unable to breathe, showing signs of overdose, expressing suicidal thoughts, or behaving violently — call local emergency services right away. If you're in the US and need immediate support for yourself or someone in emotional crisis, you can call or text 988 (Suicide & Crisis Lifeline) at any time.
