It already exists: GHB. The problem is the drug’s reputation and the problem with dosage, which could be alleviated when legalized. It’s also addictive but then again, so is alcohol but alcohol wrecks your health.
Source : addiction happened to people i met and the HR happened in a friends party.
sounds like caffeine (from those criteria)

It's pretty easy to drink 3 cups of coffee and not come anywhere near overdosing on caffeine. And then after that you can drink 3 more. And then after that you are probably sick of coffee, but go ahead and drink 3 more if you really want.
How's the recreational dosing of GHB go?
Example: https://www.inquisitr.com/1909754/caffeine-powder-death-teas...
I've never taken GHB and don't plan to, but it looks like a recreational dose is ~1/2 of a dangerous dose, both of which would be (at least somewhat) difficult to obtain.
With caffeine, the typical recreational dose is a beverage that is easily obtained and isn't dangerous. That you could buy caffeine powder doesn't make that a typical way to consume it.
Apparently 500 mg of caffeine is considered potentially dangerous. That would be 5 or 6 cups of coffee (I'm in the habit of drinking that much coffee and have a pretty low resting heart rate during the consumption, so I dunno).
