i don't know but i ground up about 2.5 grams of some really high quality that i have (don't know the strain but its good) into a frying pan layered with melted country crock. let it sizzle for about 15 mins, ate it and stayed leveled from 5 till 12. My eyes got so red and they barely ever get red anymore. I felt like i couldn't move or talk to anyone beause I was so high. That doesn't happen often for me so I recommend eating some one day.
