Rick Simpson Oil - 1ml - 434mg of THC : 440 mg CBD per syringe. Rick Simpson oil (RSO) is a cannabis oil product. It was developed by Rick Simpson, a Canadian medical marijuana activist. RSO differs from a lot of other cannabis oils because it contains higher levels of tetrahydrocannabinol (THC). This is the main psychoactive cannabinoid in marijuana that gets people “high.” Other therapeutic cannabis oils tend to contain a cannabinoid called cannabidiol (CBD) and little or no THC. In addition, Rick Simpson doesn’t sell RSO. Instead, he encourages to people to create their own using his methods. Total THC: 434 mg/g CBD: 440 mg/g 1 ML. Thanks to the highly successful documentary Run From The Cure, the Rick Simpson oil became a household name almost over night. While studies have long reported anti-tumor effects of cannabis, this was not mainstream knowledge until the documentary about Rick’s cancer cure let the cat out of the bag. Ever since, a large number of people suffering from various diseases have been experimenting with the Rick Simpson oil, and indeed many have anecdotally reported staggering results of remission.
