A hallucinogen type drug for people who stay up on it.
When taken for "fun" (And yes, it's fun), a dose of 10mg+ will have you feeling light and fluffy. A certain tinge and hints of glow surround you. It's pretty fucking cool. Might have some trouble remembering what happened when you were 'on the ambs' , but it's all good. You were alive in the dream, remember?
Don't drive on it.
