Banned in Boston: Without Vaping, Medical Marijuana Patients Must Adapt Reuters BOSTON - In the first few days of the four-month ban on all vaping products in Massachusetts, Laura Lee Medeiros, a medical marijuana patient, began to worry. The 32-year-old massage therapist has a diagnosis of post-traumatic stress disorder (PTSD) from childhood trauma. To temper her unpredictable panic attacks, she relied on a vape pen and cartridges filled with the marijuana derivatives THC and CBD from state dispensaries. There are other ways to get the desired effect from marijuana, and patients have filled dispensaries across the state in recent days to ask about edible or smokeable forms. But Medeiros has come to depend on her battery-powered pen, and wondered how she would cope without her usual supply of cartridges. "In the midst of something where I'm on the floor, on the verge of passing out, my pen has been very helpful for me to grab," she said. She carries her vape pen in her purse in case of an emergency, but has only one cartridge left. Massachusetts imposed its ban on all vaping products, including both nicotine- and cannabis-based products, in response to mounting concern about the potential serious health risks. Governor Charlie Baker, a Republican, said the ban would last at least four months while new legislation and regulation is explored. More than 800 cases of a vaping-related lung disease and 12 deaths across 10 U.S. states have so far been reported by the U.S. Centers for Disease Control and Prevention. Those numbers are expected to climb. More than three quarters of those with the respiratory illness reported vaping THC, the main psychoactive ingredient of marijuana. Many of them used small e-cigarette cartridges, or "carts," bought on the black market, where the risk of adulterated products is high. Marijuana remains illegal under federal law, but a growing number of states allow it for medical or recreational use. Massachusetts is one of 10 U.S. states that allows both uses, along with the District of Columbia. Some marijuana users had long eschewed vaping even before the ban, often on the advice of doctors who saw the cocktail of compounds being inhaled into lungs as risky. "I have advised against the vape carts for my patients for a long time exactly out of suspicion of basically what just happened," said Dr. Ryan Zaklin, a doctor in Salem, Massachusetts. "Who the hell knows what they're putting in them?" Some patients like vaping because it is more discreet than traditional burning of marijuana "flower." The devices are small, produce a relatively odorless "vapor" and is fast-acting: a handheld device rapidly heats liquid compounds into an aerosol that can be inhaled into the lungs. .
