That's great, good for you.

I think drugs are great, but they can be very harmful for people who are already mentally unstable. I deal with homeless people frequently, and in many cases, abusing drugs is a major problem for them and giving them money just perpetuates a self destructive cycle that eventually ends with them dying before their time.

Someone not getting something they need to live is the worse problem, which is why sending your charity off into the interwebs with hopes and prayers that it has a positive impact is a very naive and lazy way of doing things. You should be making sure that it helps those who are most desperate, and the only way to ensure that is to do your giving IRL.
