What are two physical indicators of the upper extremities of the body of chronic methamphetamine dependence?

Two physical indicators of chronic methamphetamine dependence in the upper extremities of the body include:

1. Track marks or injection sites: Chronic methamphetamine users may inject the drug into their veins using needles, which can leave visible marks on their upper extremities, such as the arms. These marks may appear as small scars, bruises, or puncture wounds.

2. Dermatological issues: Methamphetamine abuse can cause skin-related problems, including dermatitis, acne, or skin picking. These issues can frequently manifest on the upper extremities, resulting in visible sores, scabs, or wounds.
