Biomass ("trim") was very easy to source leading up to CA recreational legalization in 2018. For those of you who don't know the majority of cannabis nationally comes from CA and OR. Legalization brought with it enforcement against unlicensed NorCal farms that drastically reduced supply. This was amplified by the massive overproduction of the 2017 market that had many farmers leave the market due to extremely low prices. This is evidenced by the shutdown of soil/grow supply warehouses throughout NorCal.
By February 2019 the last of the October 2018 harvest had been processed to distillate. Many operators started reprocessing waste material. At the same time, distillate started to make it's way over from Mexico. There is a drought of product in the black market but wholesale buyers were reluctant to pay higher prices after becoming accustomed to the low prices of 2018. In the beginning unscrupulous sellers started diluting their product by 60%. Buyers eventually caught on to the charade and started paying attention to the reduced viscosity of the oil as an indicator of cutting agents. Sellers countered this by adding thickening agents.
Now you have an illicit market with high demand, not enough supply, and customers that represent established black markets across the country that don't want to pay a risk premium for oil.
The cutting agents themselves are expensive so people have started making their own. Now people are getting sick from the cutting agents.
