1 pound bulk went from about $2 in the 1910's to $10 in 1920s back to $2 in 1930s. Adjusted for inflation and the chart data for years ending in 7's that's $34.49 in 1937, $136 in 1927, and $72 in 1917 per pound. Right now if you are a licensed producer you can sell bulk marijuana for processing for about $100 trim, $200-250 flower, in Oregon. So it sounds about right. It sells for $15 a gram retail, which is an incredible markup ($15 * 454g/pound = $6810 per pound) but the processors only get between 5-15% THC/CBD extraction yield per bulk pound, and for whatever reasons the retailers sell it at 100% markup.
