There is simply not enough information available to physicians to make an informed decision that could help their patients.
There should be a way for studies to be conducted so that MM (medical marijuana) is available for studies and tests.
Prescribing doctors presently have the ability to speak to pharmaceutical company reps to obtain more information regarding whatever drug the pharmaceutical company is producing. There are no reps yet that can provide accurate information for MM.
