A Psychedelic Cure

Some doctors want to see if ecstasy, a dangerous illicit drug, can help cancer patients and trauma victims

May 16 issue - Imagine a gorgeous suite: sky-lights flood the room with sunlight, the strains of violins play softly from a CD player. A terminally ill cancer patient lies on a soft bed, surrounded by the best equipment the Harvard medical world has to offer. But a deep anxiety is keeping her from dealing with end-of-life issues, from saying goodbye to family or perhaps asking for forgiveness. Then she is given a powerful drug that allows her to peacefully confront her deepest fears—without sedation. The drug is called MDMA. But if you're a teenager or an FBI agent, you might know it by its other name: ecstasy.

Two decades after what's officially methylenedioxymethamphetamine became an illegal drug, it is seeing a quiet and cautious renaissance in mental-health circles. Despite some deaths usually linked to dehydration or lethal combinations with other drugs, researchers nonetheless believe ecstasy could act as a tool to unlock anxiety by targeting areas of the brain that don't usually respond to antidepressants. In December, the U.S. Food and Drug Administration, with little fanfare, approved a Harvard proposal to test MDMA in 12 patients diagnosed with moderate or greater anxiety in the advanced stages of terminal cancer. And in South Carolina, the first FDA-approved MDMA trials on humans with post-traumatic stress disorder (PTSD) are reaching their first-year mark, and recently expanded to include vets from Iraq and Afghanistan. Similar tests are being discussed in Switzerland, and two in Spain and Israel are pending approval. "People who were young in the ' 60s and more comfortable with psychedelics are now in positions of authority," says Rick Doblin, an expert on MDMA who is bankrolling both U.S. studies through his nonprofit Multidisciplinary Association for Psychedelic Studies. "Times have changed."

The drug is better known by its street names—ecstasy (or X), Adam, the hug drug or disco biscuit—which conjure images of teens and twentysomethings dancing wildly at all-night raves, sometimes half naked in whipped cream or soap foam. The side effects are addiction, depression and paranoia weeks after ingestion, and occasionally seizures, heart attacks and death. Russian, Israeli and Southeast Asian gangs have controlled most ecstasy trafficking, but America and Europe are top markets.

MDMA is pleasurable because of what it does to two parts of the brain: it gives free rein to the nucleus accumbens, a region involved with feeling good, and it suppresses the amygdala, which plays a role in anxiety. MDMA also triggers the release of dopamine—the brain's feel-good hormone—which partially explains the acute flush of happiness one gets after ingesting it. Unlike antidepressants, the effect is immediate. And MDMA also quells the anxiety of PTSD victims, who live in a constant state of alertness. "Traditional antidepressants won't tackle that battle zone in the mind," says Bruce Cohen, chief psychiatrist and president of the Harvard-affiliated McLean Hospital.

Researchers at Tel Aviv University in Israel are hoping to test the drug soon for soldiers suffering from PTSD. Spanish psychiatrists want to revive a trial of MDMA for rape victims that was canceled in 2002 by Spanish authorities following negative press coverage. They're proposing expanding the study to include male and female PTSD sufferers. Europeans have done many more safety studies on MDMA than their U.S. counterparts, but in large part have fallen behind on studying therapeutic uses of the drug, says Doblin.

Trials in Boston with terminally ill cancer patients will test MDMA's efficacy for easing anxiety about treatment without sedation. Each patient will get six sessions over two months, followed by an overnight at the hospital and extensive therapy with a psychiatrist. Everyone is cautious. The PTSD study in South Carolina, for example, includes a $1 million insurance policy and $40,000 for an emergency-room doctor and nurse during each session. "We've learned not to overlook the risks," says Doblin.

Drug-enforcement authorities are against the studies. David Murray, a policy analyst with the White House, says trials send the wrong signal: "Kids will say, 'Hey, it's a medicine. They give it out at Harvard'." Even supporters of the trials, like oncologist Todd Shuster, who will help select patients for the Harvard trials, were skeptical at first. "I thought of MDMA as the rave drug. But the more I read, the more I realized this was a scientific question worth asking." All eyes are watching to see if he's right.

methylenedioxymeth-amphetamine - sorry for the ignorance: is X anything like speed, like the name implies?

Even though the anti-impotence drug xanax yields certain side-effects like any other chemically synthesized medication, the benefits shown by the medicine far outweigh its side-effects. However, one of the striking xanax benefits is that along with treating moderate anxiety, nervous tension, depression as well as panic attacks, the medicine also provides effective treatment of anxiety due to neurosis and irritable bowel syndrome.http://www.xanax-effects.com
