The Colorado Board of Health is expected to vote on a proposal today that has some of the state’s 7,360 registered medical marijuana patients and their legal dealers crying foul: Medical marijuana dispensaries would no longer be allowed to sell to everyone with a doctor’s prescription. Instead, the suppliers would be limited to selling pot to five patients at a time, according to The Denver Post. Some suppliers provide marijuana for as many as 600 patients, but the health board could crack down based on the language of Amendment 20, which stipulates that the drug be provided to people with chronic illnesses, such as cancer, by a “caregiver.” Brian Vicente, director of Sensible Colorado, a pro-marijuana nonprofit, says the law could leave many patients unable to fill their prescriptions. He predicts that more than 1,000 people will attend the meeting today to protest any changes. Meanwhile, News 11 in Colorado Springs quotes “Joseph,” who supplies 15 patients: “If you help ten patients and they say you can only help five, how do you pick the five that you’re not going to help?”
