Yeah dude... the leaves are kind of a shitty way to get high on Salvia... you have to smoke many, many bowls out of them before you can feel anything.

If you smoke all of it and nothing happens, go out and get some extract in steadily increasing amounts (I get 5x, 10x, 15x, and 20x for special occasions).

Of course, you can also try to make a "quid" if you want, they are pretty cool. The way you make them is on this site. Also, take a look around here, they have loads of useful Salvia information. Hope this helps.
