if using medical marijuana for medical use and on probation could the judge over rule the state law of patients marijuama law in Mass?

i was put on probation on April 17th for 1st count of armed robbery one of the requirements was to stay off of marijuana but during that process the state passed a law for qualifiying patients to abtain and use medical marijuana, so on the 28th of may I had made an appointment to see a doc who was specialized in evaluating patients for the use of medical marijuana I, when going to talk with the doctor I asked him If it was ok to use this and be on probation the doc said that everything should be fine this all threw legal documentation so I went to my p.o gave him this and told him I was using this for medical purposes he told me I was in violation being found in violation resulted in being put in level 3 occ now im having troublr stoping because I do not like taken pills I rather just use my marijuana. how should I go about this a lawyer who owns the clinic I went to tells me to get an appeal and fight it any other sudjestions??
