Very interesting read about Rick Simpson Hash Oil. The article is by Rick Simpson. http://www.kindgreenbuds.com/medical-marijuana/rick-simpsons-hemp-oil/
I made some without even looking at the tutorial. 2pounds of leaf/shake and 1gall napatha= 23gs of 55% thc oil
2 pounds = 23g? Id rather stick to bubble. I said do you speak my language, he just smiled and gave me a vegemite sandwich. I come from the land down under.
But thats all from the junk most people would throw out after trimming there bud. Spending 20 on napatha oil and 3 hours of time made me almost a grand.
