The homophobe Mob and Small Marge don't believe in stats and facts so let me provide a few:
1) According to the Seattle Times in an article published in April of 2018, according to Project Homeless, overdoses were the leading cause of homeless deaths in King County (Washington) in 2017.
2) Overdoses from drugs or alcohol among younger homeless people — ages 15-24 — were more than twice as common as overdoses among people the same age who weren’t homeless, according to the report.
3) A 2018 survey of 900 homeless people asked what led to their homelessness. 24% said lost job while 21% said alcohol and drugs led to homelessness. Let me remind you alcohol and drugs usually lead to you losing your job. The two usually go hand-in-hand.
