Low-dose ketamine feels a lot like alcohol too, but feels "cleaner", leaves your system sooner, and doesn't resulting in a hangover.

25mg orally would feel like a mild alcohol buzz, and would last for up to 4 hours.

Around 10mg nasally (either as powder or as a nasal spray) would have a similar effect, but would only last up to 2 hours.
