as a first offense in MD, you only need to pay a fine - even though the misdemeanor will appear on your record. it is not a jailable offense.
if you are on supervised probation on the DC offense your probation agent can certainly pick up the offense on a "ticker" as it will be placed in a database. if you are not on supervised probation, then the DC courts will not be notified.
if you have a probation agent in DC and they do get it from the database, then the DC court can impose any suspended sentence - and in DC the penalty is 6 months -
it is possible the case manager can obtain the database or has an established ticker the same way a PO would.
your DC case is considered pending until you successfully complete the terms of the probation and, yes, only then can the matter be dismissed.
i do not think you will be placed in jail for 6 months in DC for the probation violation. you may get written up and you will need to appear before the court. but given the amount of marijuana you had and depending on how long you have been on probation, and if you have a job i do not believe you would get jail time. it is possible the court would admonish you and make sure you are doing a substance abuse awareness program.
what can happen is the diversion is taken away and you can be placed on supervised probation
