Mental illness is strongly corelated with substance abuse. The chronic over-stimulation 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.
