(Gillian Flaccus | AP) Two-time cancer survivor and medical marijuana cardholder Bill Blazina, 73, smokes a marijuana joint on the deck of his neighbor's home in Waldport, Ore., in April 2019. Blazina also uses a high-potency marijuana oil as a medical marijuana patient but he can't afford it at a recreational marijuana store. Blazina has learned how to make his own oil in a rice cooker after watching online videos.
