What Are the Physical Signs of Abuse or Addiction?

The physical signs of abuse or addiction can vary depending on the person and the drug being abused.

In addition, each drug has short-term and long-term physical effects. For example, someone who abuses marijuana may have a chronic cough or worsening of asthmatic conditions. Stimulants like cocaine increase heart rate and blood pressure, whereas opioids like heroin may slow the heart rate and reduce respiration.
