Seed - sow spring in a greenhouse and only just cover the seed. Germination usually takes place within 1 - 3 months at 10°c. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood 10 - 12 cm with a heel, July/August in a frame. Plant out in the following spring[200]. Cuttings of mature wood, 12 - 17cm with a heel, October/November in a sheltered position outdoors. Plants root by the spring. Good percentage[78].

I can't find detailed information on the available substances in the cell content. What about the smell of cannabis when touched or wet? It is from the non-edible non-medicinal contaminants, of course: might it be good to smoke?
