Dollars spent is a poor metric for effectiveness. If you were to become homeless in SF tonight, is there shelter available for you to sleep in?

Homeless and drug addicts are not the same.

Letting the homeless block streets with tents is not the same as caring for them, or rehabilitating them.

correct. my comment was intended to point out the disturbing misplacement of priorities, given that the budgets for educating the citizens of the future and for fetty smoking bums are comparable.
