My friend makes awesome tincture by soaking buds in booze. He soaks it for months then drains it, strains it and adds fresh buds for a couple more months. Just 2 ml of this tincture will rock you within a few minutes after ingesting. It tastes nasty so I put it under my tongue. By the time the tincture is gone my tongue is numb. A couple of minutes later I am high.
