The Maryland medical marijuana bill that has already passed the state congress was given preliminary approval by the state senate last Friday. The final step would be Govenor O'Malley's signature.
The bill already has support from Maryland Secretary of Health, Joshua Sharfstein, who opposed the previous incarnation of the bill. His opposition then was only because he feared state employess might be prosecuted by the feds. The new bill takes that concern into account, and gives Govenor O'Malley the option to suspend the program if it's determined that state employees are in danger of prosecution.
If the bill goes into effect, it'll mean the creation of state commission that will be in charge of medical marijuana programs at academic medical research centers that have chosen to participate.
