Monday Illinois will initiate a four year trial program that will allow residents with one of the 40 qualifying conditions to use medical marijuana, according to the Chicago Tribune.

There are eight dispensaries scheduled to open tomorrow. Patients will have a limit on how much marijuana can be purchased. The legal limit will be two and a half ounces every two weeks.

The state will authorize a total of 60 dispensaries and 18 grow houses over the next year. The trial program is scheduled to end in 2018, and the state will then have to determine a permanent statute.
