how long

[lateralus]

I feel it after I exhale the first hit. After I'm done smoking, it creeps for maybe five to ten minutes before it's full blown. The duration of the stone depends on how much I smoked, but generally it lasts about two or three hours with a good buzz, and another few hours of hangtime (afterglow).
