Ray Stern, Phoenix New Times:  “The final rules for medical marijuana are too tough on patients and may encourage a lawsuit, says one Valley doctor.  Edgard Suter, an East Valley nuclear medicine physician who has been an outspoken advocate for medical marijuana, decried an addition to the draft rules that requires doctors to state the underlying condition causing “chronic or severe pain.” He already was unhappy that state officials plan to monitor the recommendations that physicians make and turn in prolific recommendation writers to medical boards for possible discipline.”
