Full Extract Cannabis Oil (Rick Simpson Oil aka RSO) is incredibly potent, edible, concentrated cannabis. The budtender at Sparc recommended dropping a grain of rice size amount onto dried foods like chips or cookies. I did not expect to feel such sedation from the amount shown on the French fry, but I did within 30 minutes. RSO is suggested for patients in a lot of pain, I had picked some up today to bring down to @bernman49 who just had his appendix removed. Feel good and heal quickly Bern!
