If the person is only charged as a co-conspirator in Maryland as opposed to the actual offense itself, the person will be more likely to receive a misdemeanor if the drug charge is a felony. The maximum penalty associated with the charge of conspiracy, though, is exactly the same as for the underlying charge itself.
For example, a person who is charged in Maryland with conspiracy to distribute marijuana would be facing the same fines or maximum penalty as somebody who is charged with simple distribution of marijuana.
