A seemingly long period of time. It occurs most often when under the influence of marijuana due to the altered state of mind. An actually short moment may seem to drag on forever.

Get the marijuana minute mug.
when you smoke grass you feel very relaxed, distances seem to be shorter making places and objects seem closer to you than they really are. Also, perception of time is distorted - a span of a few minutes may seem to last for more than an hour or so. But you're feeling so calm and serene you don't really care. One minute under the influence of Mary Jane is a marijuana minute.
At the Pink Floyd concert there was some maximum pot smoking. Jeffrey pulled out a fairly large reefer. Me and him took turns toking. The band kicked into the psychedelic warhorse "Astronomy Domine" which is best described as sounding like "rock'n'rollStar Trek". WOW!
That song ran for about 4 minutes or so but it seemed to last more like around 40 minutes to me. That's marijuana minutes for you.

The amount for time that passes when you're high that feels like it has only been a minute. Usually 2 real hours are about 5 marijuana minutes.
Stoner 1: Fuck dude. How long have we just been sitting here?

Stoner 2: I don't know man. It feels like 10 minutes but it's been like 3 hours. We must be running on marijuana minutes.
