Sure, but I think you're making a correlation=causation connection... I'd argue that those forced into homelessness are more likely to turn to drugs, which then leads to a cycle of poverty that's difficult to break out of.
If LA had more affordable rent, a lot of those people currently living in tents would have more privacy, more stability, less temptation to turn to cheap drugs to cope.
