Ya fuh real -- you can't get truly high from leaves... I've heard people claim they got "a little head change from male leaves" but I'm pretty sure that's bogus. Actually the guy who did the male leaves smoked it out of a joint so in his case it was def. in his head.

HOWEVER... female characteristics often develop before the clear hairs become totally visible... One of my plants started smelling skunky 1 or 2 days before it started revealing it's hairs.
