Medical marijuana is medicine. If you are going to prevent patients from having ready access to this medicine, then you had better remove other medicines from the pharmacy as well. Why do officials single out marijuana? It seems illogical. Especially since many of the other legal prescription drugs have side effects far worse than marijuana.
Of course it’s a problem when any unauthorized person gets their hands on medicine not prescribed to them, but you can’t ban everything because it may be used inappropriately. If that were the case, we would have to ban cars, guns, booze, prescription painkillers and even all sharp objects.
