If they told you it was to buy drugs, would you still give them money? It's not different from giving them the drugs directly.

I would personally prefer to give money to someone that needs it to eat.

Yeah I admit I am in two minds. Id rather the state give them clean safe pure drugs and then help them get off the drugs with naltrexone or whatever is best.

Outside of drugs and drink they can spend it how they like. They choose the food or maybe save for a hotel night.
