The D.C. Council has passed a measure to legalize medical marijuana, sending the bill to Washington Mayor Adrian Fenty.
Under the measure passed Tuesday, the nation's capital would join 14 states that allow medical marijuana.
Patients with chronic illnesses such as AIDS or cancer could obtain marijuana with a doctor's recommendation. It would be given out at five to eight distribution centers.
Patients would be limited to two ounces of marijuana per month.
If Fenty signs the bill as expected, Congress would have 30 days to review before it becomes law.
In 1998, residents voted to legalize medical marijuana, but Congress blocked the initiative from taking effect for years.
