if you are talking about the sativa durban poison, it is a more heady high reather than body stone. its something you could probably smoke and not get that couchlock feeling. it is a very tall growing plant so when sexing, sex early enough to allow about 2x the growth. again being a sativa/mainly outdoor strain it grows tall and needs a lot of light. if you lack light you will get very stretchy airy buds. the few i am aware of were sexed at about 3' or so and ended aroud 6.5'. flavor is more of an odd fruity taste rather than licorice. very nice smelling plant during flower.. again just make sure you have enough light. that is why it is normally classified as an outdoor strain. hope this helped a little bit.
also, wanted to add, being a sativa the flower time is about 10-12 weeks opposed to the standard indica 7-8 weeks.
