Yeah, you can smoke the leaves but they only have about 1% THC. You MIGHT get high, but probably only get a little buzz.
If you want to actually get high off of it then make some honey oil. There's a great thread (which I can't seem to find) on using butane to make the honey oil, only takes a few mins not hours or days, but it does cost between $6 and $9 for the 2 to 3 bottles of butane.
Out of a 2 foot male I got enough honey oil to seriously fuck me up. I mixed it with some of the dried leaves from the plant so the oil would have some sort of transport medium. I think I got about 4 or 5 bowls worth. A single bowl got me seriously high, really nice high too, it was almost like an acid trip without the strong visuals. Like if LSD and marijuana had a baby and I killed it and smoked it.
