The radio headline had stated that the University of Virginia had found the cannabinoid in cannabis THC could kill cancer in mice. He figured that if it kills cancer in mice it would kill his cancer too.
Rick's decision was to apply cannabis oil to his skin cancer. He applied his cannabis oil to some bandages and put them on the skin cancer. After 4 days of waiting he decided it was time to see if anything had happened under the bandages. To Ricks surprise the cancer was gone. His cannabis oil had cured his cancer.
When Rick discovered that the hemp oil (with its high concentration of T.H.C.) cured cancers and other illnesses, he tried to share it with as many people as he could free of charge, curing and controlling literally hundreds of people's illnesses... but when the story went public, the long arm of the law snatched the medicine - leaving potentially thousands of people without their cancer treatments - and leaving Rick with unconsitutional charges of possessing and trafficking marijuana!
