I have seen the day when LEAVES was all we could get. We got a headache and a slight high. The FAN leaves have resin, but they still don't get you THAT high. I tried some of my little leaves that I could see the trichomes on, just to see if I got anything, and I got a small slight buzz.
i had some jamaican homebois who would use the fingers of the leaves as rolling papers. not sure how to get it to stick other than a reg paper or two on the outside. i feel its a good way to enjoy your whole grow after makin some hash first. my $0.02
