Illicit Opium Production
Virtually all illicit opium is produced directly from Papaver somniferum. There are two things worth noting in the table below. The first is that the amount of land used for illicit opium production is five times that used for all licit production combined. This is roughly equivalent to the the contrast of licit and illicit opium on the world market.
The second noteworthy element of this table is the opium yield which is half that for licit production. It is most likely the result of the fact that illicit opium is produced on a large number of small farms whereas licit opium is produced on large commercial farms which have been optimized. It is also probably due to the limited availability for the small illicit farms of fertilizer and other farming production tools.
