When the oil first arrived on the scene it was potent and tasty. Honey oil being the primo oil in my area. After a while the quality did diminish. That was about the time that Thai Sticks and other high quality weed began to appear. People preferred the quality weed over the messy oil. Hash was always prominent with some very good product available.Yes the black oil was the best of it all,made with chloroform I was told,it had outrageous potency,the red /cherry would be hit and miss where I lived.
