When monitoring effects of psychotropic substances, a commonly used term for a level that produces a just perceptible effect is "museum level." This is a slightly-over-threshold level which allows public activities (such as viewing paintings in a museum or scenery watching as a passenger in a car) to be entered into without attracting attention.

Get the museum level mug.
The dosage of psychoactive substance (particularly 2CB) whereby you can feel the effects, but not appear to be an obvious dope fiend when in public. As coined by Dr Alexander Shulgin.
Ye man, I've got a really nice, like, museum level of high going on.
