Like it or not, the advent of recreational marijuana is going to change a lot, including how the medical pot program works. When the state approved a medical marijuana program in 2007, it put limits on how much enrollees could buy, 8 ounces every 90 days. The state tracks sales through a registry. Then came the approval of recreational cannabis in March. Lawmakers put no limits on recreational marijuana sales; those 21 and older will be able to buy up to 2 ounces at a time, no limit on the number of purchases. The state said last week it does not plan to increase purchase limits for medical marijuana patients until after recreational sales kick in, in part to prevent product shortages.
