That is ~$5700 per pound. To put that into perspective, Beluga caviar, the most expensive caviar produced from the critically endangered Beluga sturgeon, is apparently only ~$4000 per pound and saffron, what is traditionally known as one of the most expensive bulk-produced spices, is ~$5000 per pound at retail. Tobacco, a reasonably close agricultural analog in the sense that you harvest the leaf for recreational drug use is ~$4000 a ton which, from perusing wholesale prices of agricultural products, is fairly close to the upper end of price per ton of a easily harvested agricultural product.
