Colby had diagnoses of depression, anxiety, panic disorder, paranoia, and schizophrenia. Yes, he died of a heroin overdose. But, so many people do not consider mental illness as a reason for drug use. Not all drug users are mentally ill, but you can see by the statistics that a good number of them are. Mental illness has such a stigma. Would people think differently of someone if, rather than a drug overdose, they had passed from a heart illness, or a liver illness? Sadly, I think they would. The difference is that a heart ailment or a liver ailment usually does not cause people to behave differently. A mental ailment does.
