Some of the most significant consequences of substance abuse are physical in nature. Depending on the type of substance used, drug use can lead to heart attacks, strokes, respiratory problems, seizures and organ damage. In the most severe cases, drug use can even lead to coma or death.
Excessive alcohol consumption is also an issue, especially when it comes to liver function. Alcoholism has been linked to cirrhosis, a condition characterised by the accumulation of scar tissue in the liver. When scar tissue replaces healthy tissue, the liver doesn’t function as well as it should, leading to yellowing of the skin and eyes (jaundice), fluid accumulation in the abdomen and other symptoms.
