John Kofel pets his faithful dog Kirby before taking his daily dosage of CBD and THC oils, which sit on the table next to him at right, at his home on June 19, 2017 in Aurora, Colorado. Kofel has prostate cancer and uses CBD and THC oils daily, morning and evening, to help fight the disease. He uses an eye dropper to put the oil on his tongue. He also has a ton of supplements he takes daily to fight cancer as well. (Photo by Helen H. Richardson/The Denver Post)
