Correlation between mental illness and substance abuse

This is an 8 page research paper(not including the title page or works cited page) for my ENC 1102 class. There needs to be 8 sources, doesn’t matter if they’re books, journals, websites, just no Wikipedia is allowed. My teacher is a freak about MLA Format. The research paper is about the correlation between mental illness and substance(drug) abuse. I’ve found that the 3 main drugs abused by those with mental illness are alcohol, cocaine, and heroine. Please let me know if there are any questions! There really are no limitations, you don’t necessarily need to focus on these 3 drugs. Just needs to be a research paper on the correlation. Thanks sososo much!
