i was interested in growing some poppies cause opium kicks ass.... got to doing some research and found some dea reports on the poppy fields in afghanistan which gave avg. yield per hectacre.... after some simple conversions and division; i reached the figure of a yield of anywher from 0.25-0.35grams of actual opium resin yield (assuming you scored the pods at just the right depth) per sq. ft. of planting area....not worth it in america. you would need a rather large area to produce anything worthwhile... but in theory; a 10x10 area could produce you up to 3.5g; which, when mixed in small quantities with weed, could last you a decent amount of time.... could possibly be worth it... keep in mind that the afghans plant really close together, so a 10x10 area would still be a rather large quantity of plants.
