The Physical Manifestations of Drug Abuse
Long-term drug abuse often leads to a host of physical symptoms that affect the body’s immune system. For example, the health of essential organs such as the heart and lungs, and even the physical structure of the brain itself, can be impacted. Meth addicts often experience severe dental issues, skin sores, compromised immune systems, and more serious medical complications.
Heroin users may deal with pneumonia and other lung issues from the drug’s respiratory effects. They also have greatly increased risks for diseases like HIV, collapsed veins, and clogged blood vessels, among other symptoms. 
Addiction’s Cognitive and Emotional Damage
The cognitive and psychological damage caused by drug addiction can be as destructive as any physical symptoms. Many drugs, such as cocaine or methamphetamine, cause physical changes to structures in the brain related to cognition. This can have profound effects on a person’s memory, coordination, decision-making abilities, and emotional control. Most of these changes in the brain result from long-term use that is associated with an addiction – classified by medical experts as a disease that changes how the brain works. 
The Threat of Drug Overdose
A final health risk of long-term drug abuse is overdose. Many drugs, in particular opioids like heroin or fentanyl, present high risks of overdose to users. Overdose can result in unconsciousness, permanent brain damage, or even death. Many losing their lives due to a single bad dose of fentanyl-laced heroin or cocaine. Overdoses from opioids can be treated if one acts quickly, with the opioid antagonist known as Naloxone, or Narcan.
