I said it in my own top level comment too but I'll post it again here sibce you're asking. I'd highly recommend ketamine as an alt drug. At low doses like a bump or three it's a perfectly functional alcohol substitute except there's no hangover or feeling sick after.

It makes me wanna dance and does a better job of mitigating social anxiety. If I'm in a crowd it literally makes the people appear as if they are further apart than they were before I took a couple bumps.

Loading it in a metal bullet I can discreetly use it in just about any setting. You just gotta make sure you go slow and small so you don't get k holed in public lol
