Evidence of How Drug Helps With Specific Diseases Lacking CHICAGO - Even though 20 states have passed laws legalizing medical marijuana, swayed in part by thousands of personal testimonies, current research hasn't nailed down exactly if, and how, marijuana alleviates all the specific diseases the drug is being legalized to treat, experts say. A number of proponents believe marijuana could benefit people with everything from glaucoma to cancer, and it's been legalized in Illinois to aid patients with some 40 medical conditions. But opponents of its medicinal use believe the risks of smoking medical marijuana outweigh the benefits, while others question whether patients really improve or only feel like they improve. Marijuana's best-known compound is THC, but the plant actually has 105 unique cannabis compounds with potential for medicinal use, proponents say. THC has already been approved by the Food and Drug Administration in synthetic form to help patients with nausea and decreased appetite. Some scientists believe the plant's other compounds - called cannabinoids - could have equal promise. Although research has increased in recent years as more states legalize medical marijuana, solid evidence of how individual cannabinoids could help people with specific diseases has been significantly lacking, a review of medical literature and interviews with experts shows. Researching the potential effects of marijuana's various components on conditions such as multiple sclerosis, fibromyalgia or lupus could have serious implications for doctors who want to prescribe medical marijuana to patients. While most medicines derived from nature are tested before they reach the masses, the process to evaluate marijuana has been confounded by its longtime status as an illegal drug. A complicated federal approval process and limited availability of research-grade marijuana add to the difficulty. The only study specifically cited in Illinois' law, signed by Gov. Pat Quinn in August and set to go into effect next year, is a 1999 Institute of Medicine report. But Dr. John Benson, a lead editor of the report, said legislators stretched the conclusion of the book-length study when it said modern medical research "has confirmed the beneficial uses of cannabis." While the report did say there was promise that marijuana could have medical benefits, it also suggests researchers need to continue to dig deeper into the issue. It also says marijuana should not be smoked, he said. In Illinois, legislators relied mostly on personal testimonies and compared notes with states that have also passed medical marijuana laws. [sidebar] One man's story Mike Graham of Manteno, Ill., was one person who shared his story with Illinois legislators. A little more than a decade ago, he was using 14 different pharmaceuticals. Living with an extremely painful degenerative spine disease, he has been through multiple surgeries in efforts to remedy it. But doctors feared one more could paralyze him, so he took medications for pain instead. When he was in his late 30s, doctors sent him home with a hospice care nurse. After reviewing his medications, she told him he would die early if he continued taking all of them. To his surprise, she recommended pot, he said. "I almost fell out of bed laughing," Mr. Graham, 51, said. "I come from a law enforcement family." Increasingly desperate, in 2002, he decided to give it a try. He was able to cut back on all his previous medications except a morphine pump under his skin. Now, he takes three or four puffs of marijuana in the morning and at night. Once down to 135 pounds, the more than 6-foot-tall Mr. Graham now says he's back up to 250 after regaining his appetite. "What it comes down to here (is) I wouldn't be here if I hadn't made that decision," Mr. Graham said. - --- MAP posted-by: Jay Bergstrom
