I've been picking up green marijuana prescriptions from my local park and documenting what I am finding. How does one tell an actual prescription versus some just bringing and smoking marijuana in the the park. It would be helpful that legitimate prescription labels must include the name of the person who has the presciption, the name of the doctor and the doctors phone number and the location and phone number of where the product was purchased. I am going to suggest state legislation along these lines to - until such time that the laws regarding marijuana change. Until the day when the product is completely legal and effectively regulated other measures need to be in place.
