(Medford, OR) -- Police are seizing 500-million dollars worth of illegal marijuana in a bust outside of Medford in southwest Oregon. The Oregon State Police served a warrant at five industrial-sized warehouses on Thursday. Over the course of two days, police estimated they removed 500-thousand pounds of illegal marijuana and a gun from the premises. Individuals arrested were discovered to be migrant workers living on site and were released after they were identified. The seizure comes at time when the sale of legalized marijuana is flourishing. CNN reports sales nationwide hit 20-billion dollars in 2020 and are set to top 26-billion dollars this year.
