LOL! It would have been healthier, as explained in the video and links, if Alice has served the leaves raw in salads. But not nearly as much fun . . .
You know, since it is the flowering tops (the "buds") which contain the highest concentration by far of the psychoactive compounds and it is the non-pschoactive compounds found in higher concentrations in leaves and roots (stems too, but those are hard to juice), I am thinking that if someone knew a pot grower they could probably get a good supply of leaves and such for a pittance. Keeping in mind, of course, that the powers that be consider the leaves, stems and roots to be just as illegal (where applicable) as the flowering tops.
