Signs of IV Drug Use: What to Look For and How to Help

Intravenous (IV) drug use – injecting drugs directly into a vein – carries some of the most severe health risks of any route of drug administration. It also leaves visible evidence. Knowing what to look for can help family members recognize injection drug use in a loved one and understand what level of medical and addiction risk they may be facing.

Physical Signs of IV Drug Use

Track marks The most recognizable sign of IV drug use. Track marks are puncture wounds along veins from repeated needle insertion. They appear as:

Signs of IV drug use: Risk and Treatment Response Snapshot

This table is designed for families and adults trying to decide whether professional help is needed now or whether a lower level of support may be enough.

What you may notice	Why it matters	Possible next step
Repeated use despite consequences	Loss of control is a core sign that use has moved beyond experimentation	Confidential assessment and treatment planning
Withdrawal, cravings, or using to feel normal	The body and brain may be adapting to the substance	Medical review, MAT when appropriate, IOP or PHP
Mood changes, paranoia, depression, or anxiety	Mental health symptoms can both drive and result from substance use	Dual diagnosis assessment
Overdose risk, fentanyl exposure, or IV use	These are urgent safety concerns	Call 911 for emergencies, then seek treatment support

• Small red or purple dot-shaped wounds (fresh marks)
• Bruising surrounding injection sites
• Lines of scarring along veins (older marks)
• Hyperpigmentation (darkening of skin) along vein paths
• Thickened or hardened veins

Common injection sites: inner elbow, forearm, back of the hand, foot, groin, and neck (when other veins have collapsed).

• Collapsed veins Repeated injection damages vein walls, causing them to collapse and become unusable. People with collapsed veins move to increasingly unconventional injection sites that carry higher risks of infection and injury.
• Abscesses When bacteria are introduced at an injection site – from non-sterile equipment, skin bacteria, or substances used to “cut” drugs – abscesses develop. These appear as painful, swollen, red lumps at or near injection sites. Untreated abscesses can cause sepsis and be life-threatening.
• Cellulitis Bacterial skin infection surrounding injection sites, appearing as red, warm, swollen, and tender areas of skin.
• Scabbing and scarring Repeated puncture wounds heal with scar tissue. Long-term IV drug users often have extensive scarring along vein paths.

Behavioral Signs of IV Drug Use

• Wearing long sleeves in warm weather (to hide injection sites)
• Unexplained disappearances to “use” in private
• Finding drug paraphernalia – syringes, needles, spoons with burn marks, cotton balls, ties or belts (used as tourniquets), alcohol swabs
• Sudden changes in social circle
• Financial problems – borrowing money, missing money or valuables
• Physical deterioration – weight loss, pallor, appearing unwashed
• Nodding off (opioids) or extreme agitation (stimulants)
• Constricted pupils (opioids) or dilated pupils (stimulants)

Medical Risks of IV Drug Use

IV drug use carries dramatically elevated health risks compared to other routes of administration:

• Blood-borne disease transmission Sharing needles or other injection equipment transmits HIV and hepatitis C (HCV) with high efficiency. HCV in particular is highly transmissible via shared injection equipment.
• Bacterial endocarditis Infection of the heart valves from bacteria introduced through injection. Endocarditis can require weeks of IV antibiotic hospitalization and valve replacement surgery. It is increasingly common in people who inject drugs and carries significant mortality.
• Sepsis Systemic bacterial infection entering through injection sites. Sepsis can progress to septic shock and is life-threatening.
• Overdose IV administration delivers drugs to the brain within seconds, producing the fastest and most intense effects – and the highest overdose risk. Fentanyl in the illicit drug supply makes every injection potentially fatal.

What To Do If a Loved One Is Injecting Drugs

• Ensure naloxone access. If your loved one is injecting opioids or using substances potentially contaminated with fentanyl, having naloxone (Narcan) in the home is critical. It is available without a prescription at most pharmacies in Georgia.
• Do not share sharp criticism or ultimatums in crisis moments. People in active addiction with high physical dependence need medical support, not moral pressure. What works in the long run is consistent boundaries, clear communication of concern, and help accessing professional evaluation.
• Call for a professional assessment. Hope Harbor Wellness provides confidential clinical assessments for adults – 770-573-9546. Same-day assessments are frequently available. We can help determine whether detox coordination, MAT, IOP, or PHP is the right starting point.
