Going to the dentist high

Yeah dude I went high because my Family dentist is an hour and a half away so i smoked on the trip to the dentist, When i got there i was baked as all get out and the nurse opens my mouth and mumble marijuana, i paused and looked at her and she winked at me. A little wierd but it was ok, opening my mouth for all the time sucked balls though, but she sprayed that water stuff to rinse your mouth out...that was some of the best water i have ever tasted.

^^yeah they always know at the dentist for some reason. I smoked the night before I went and he knew. I wonder how they can tell.
