EXPERT TESTIMONIAL- JOYCELYN ELDERS MD, FORMER US SURGEON GENERAL, wrote the following in an article titled “Myths About Medical Marijuana,” published in the Providence Journal:
“The evidence is overwhelming that marijuana can relieve certain types of pain, nausea, vomiting and other symptoms caused by such illnesses as multiple sclerosis, cancer and AIDS — or by the harsh drugs sometimes used to treat them. And it can do so with remarkable safety. Indeed, marijuana is less toxic than many of the drugs that physicians prescribe every day.”
