it’s a common misconception that substance abuse causes homelessness when really it’s the other way around.
looking at a study of homeless people in California, 50% of respondents didn’t use drugs in the past 6 months. of those how had, 40% started after they became homeless (meaning that only 30% were on drugs beforehand). so let’s say you’re 50% to give money to a user, there’s still not even a guarantee that they would use your money on drugs when they otherwise wouldn’t. like maybe you do, but they also might use it to buy a new blanket or socks or idk cold medicine or hot food.
