Track marks are one of the most evident physical signs of shooting up drugs. People inject drugs intravenously to experience a quicker rush, leaving noticeable marks at the injection site. Tracks marks look like scars, sores or other marks in common areas for injections. Track marks on the arms, particularly the forearm, are one of the most common areas, but you might also see track marks on a person's feet, toes, neck or hands.
Some injection drug users will wear long sleeve t-shirts or sweaters to hide their track marks, even if it's warm outside. While track marks are commonly found on the arms, continuous injection drug use can cause the injection site to become too damaged or scarred, making it challenging to keep injecting drugs into the same place.
Instead, a person may inject a substance between their fingers, toes or veins in their hands. Some may even choose to inject substances into their groin or neck. Any area of the body where veins are visible through the skin can be a location for IV injections for those using substances.
If you're trying to identify track marks on a loved one, look in the most common spots, as these are the easiest to reach. Some track marks from shooting up are more challenging to hide than others, such as those on the hand or neck. Look for scarring or damaged skin, which may also have bruising. If you notice track marks on a loved one's skin, try to talk to them about their substance use and if they would consider seeking professional help.
