Mental illness is strongly correlated with substance abuse. The chronic overstimulation and toxic exposure from chemicals can easily lead to the development of a mental illness.
Substances can cause brain damage, lesions, strokes and other serious health problems, all of which can come with the development of mood disorders, anxiety, delusions, paranoia, and many other potential problems.
Diseases such as HIV and Hepatitis are also common problems for those sharing needles. Intravenous drug users who share rigs are exposed to whatever communicable diseases the other needle users have. This could translate into serious health problems or chronic, even life-threatening conditions such as AIDS.
In addition to chronic health problems as a result of substance abuse, sudden death also plagues those in active drug and alcohol abuse. Learn more about the health risks associated with substance abuse addictions and how to address them in your sobriety.
