Rick Simpson Oil (RSO) is an unrefined, potent oil extracted from cannabis using ethanol. It’s named after the man who created it and first benefited from it. Canadian Rick Simpson claims he cured his own skin cancer with a custom blend of cannabis oil, which has come to be known as Rick Simpson Oil (RSO), or Phoenix Tears (the name of Rick’s website). Since then, he has touted the benefits of medical marijuana and used to give away his eponymous oil for free.

HOW TO USE RSO:

Dosages vary from person to person depending on many factors, including the potency of the RSO, which Simpson claims is 80% to 90% THC.

RSO is typically not smoked. It is applied in the following ways:

• As a topical rubbed onto the surface of the skin
• As a sublingual (under the tongue) for the fastest absorption rate
• As a capsule taken orally for slowest-acting effects that last longer
