When states legalize pot for all adults, long-standing medical marijuana programs take a big hit, in some cases losing more than half their registered patients in just a few years, according to a data analysis by The Associated Press.

Much of the decline comes from consumers who, ill or not, got medical cards in their states because it was the only way to buy marijuana legally and then discarded them when broader legalization arrived. But for people who truly rely on marijuana to control ailments such as nausea or cancer pain, the arrival of so-called recreational cannabis can mean fewer and more expensive options.

Robin Beverett, a 47-year-old disabled Army veteran, said she resumed taking a powerful prescription mood stabilizer to control her anxiety and PTSD when the cost of her medical marijuana nearly tripled after California began general sales. Before last year, an eighth of an ounce of dry marijuana flower cost her $35. Now it’s approaching $100, Beverett said.
