Question about giving charity

Hi Everyone,

I have an interesting question I have wanted to get advice on for some time. Sometimes when i give charity I will take a few 10-dollar bills and give them directly to homeless beggars on the street. In my area in particular there are a lot of drug addicted homeless people who look/act like heavy users, is it wrong for me to give to these people who would most likely use it towards drugs and alcohol that could not only potentially cause them death or go towards fueling a destructive drug industry? P.s i always try and look for clean homeless people but i was wondering what others though on donation being given in this way is it something to be mindful of if i cannot find these clean people to give to.

Best Wishes,

Ethan
