Krieger BRAIN'S WIRING MAY WORK AGAINST RECOVERING ADDICTS Under Prop. 36, State's Drug Abusers Get Shot At One Year Of Treatment Madeleine started with marijuana and reds, then moved on to alcohol and cocaine. For 28 years she used and abused drugs, losing her marriage, children, and nearly her life in the process. She tried to quit, many times. But always she found herself trapped in the same heartbreaking cycle that ensnares many addicts: Get hooked, get treatment, get better, and then embrace drugs all over again. It is a painful circle that doctors and scientists are struggling to treat -- and more and more, it is becoming part of public health care in California. From recent drug arrests of celebrities such as Robert Downey Jr. to the very private struggles faced every day in Bay Area rehab centers, the often circular web of drug treatment and relapse has long drawn in doctors, counselors and patients trying to break the grip of addiction. Now, as California embarks on a new way of dealing with drug abusers -- treating them rather than jailing them -- the uncertain science of healing addiction is getting new scrutiny. Researchers have pinpointed ways in which drug use can cause major shifts in brain chemistry and function, making recovery for some an issue of biology as well as personal will. But several years after scientists first discovered that changes in the brain undermine attempts to get clean, it remains unclear why some people are at greater risk of dependence -- and why some may never kick the habit. ``You're asking the million-dollar question,'' said Jack Stein, a director at the National Institute on Drug Abuse. ``There's obviously a lot of factors to look at.'' What is well understood is that relapse is common -- almost inevitable - -- whether an addict is a privileged Hollywood bad boy or a former Catholic schoolgirl. Madeleine, who follows the Alcoholics Anonymous tenet that her last name should not revealed, has been sober for 25 years -- but even she still worries about the possibility of relapse. ``You're always an addict until the day you die,'' said the San Jose grandmother, who now works as a drug treatment counselor. ``For people who aren't addicts, it's hard to understand.'' Stars' struggles Disease hits some harder than others Indeed, headlines have swirled around the addiction problems of celebrities such as Downey Jr., baseball star Darryl Strawberry and supermodel Kate Moss, stars with continual troubles over drugs. For most, it just doesn't make sense that an award-winning actor and talented baseball player would seemingly throw so much away, even after undergoing multiple sessions of rehabilitation. Downey seriously jeopardized his stint on the television sitcom ``Ally McBeal'' last month after his second arrest on drug-related charges in five months. Strawberry, who is battling colon cancer, skipped out on an inpatient drug rehab program -- and a chemotherapy treatment -- to go on a four-day crack cocaine binge in March and April. Scheduled to appear in court today to determine whether he violated his probation on a drug-related conviction, he could face more jail time. ``It's just a sad fact some people are more heavily affected. Just as with other diseases, some have a worse case than others,'' said Greg Hayner, chief pharmacist at the Haight-Ashbury Free Clinic in San Francisco. That drug addiction is being called a disease -- and has even been likened to type 2 diabetes -- has raised more than a few eyebrows in the public arena. Yet there is some scientific evidence to support the assertion that drug abuse may alter brain chemistry, meaning that drug relapse may have as much to do with physiology as with a person's desire to quit. Most scientists now believe that the brain of an addict is fundamentally different from that of a non-addict. In a landmark 1995 meeting in Virginia, more than 100 substance-abuse experts declared drug addiction a disease of the brain. This concept was adopted as treatment dogma with the 1997 publication of a paper by the National Institutes on Drug Abuse. What they've found is this: Initially, the chemical pathways of the brain are not much affected by hard drug use, and the decision to take the drugs remains voluntary. But at a certain point, the drug user moves into a state of addiction marked by structural or chemical changes in the cells within brain pathways. These changes can persist long after addicts stop using drugs -- which is why relapse is so common, according to neurologist Patricia Janak of the Ernest Gallo Research Center at the University of California-San Francisco. George Koob, professor of neuopharmacology at the Scripps Research Institute in La Jolla, agrees, calling drug addiction ``a chronic, relapsing disorder.'' `It's not fair to argue that a drug addict is not responsible because they have a brain problem,'' because it is every addict's decision to take drugs, he said. But it is shortsighted to ignore the influence of brain chemistry, he said. To better understand relapses, addiction researchers are working to more precisely identify the drug-induced changes in brain circuitry that occur over time. They have found marked differences in individuals' vulnerability to addiction -- and ability to kick the habit. Therefore, the vast majority of scientists support Proposition 36, the California law set to take effect July 1, which requires that people convicted of using or possessing drugs for the first or second time be sent to community treatment programs instead of jail. ``Everything we try is useful,'' Janak said. ``Once drugs have produced changes in the brain, we have to use everything within our power to treat people.'' Current treatments, such as counseling sessions where advisers are often recovering addicts themselves, offer innovative, although imperfect, tools to assist the estimated 15 million Americans who admitted to using illicit drugs in a 1999 survey. An estimated 3.5 million said they were dependent. Although relapse rates are hard to calculate, it is estimated only one in five addicts is able to quit the habit on the first attempt. And that figure may be generous, said Alan Marlatt, director of the Addictive Behaviors Research Center at the University of Washington in Seattle. He estimates that two-thirds slip back into use in the first 90 days. Taking control Emotions can trigger relapses Most treatment programs teach addicts that access to drugs is one of the greatest relapse triggers. To boost their odds of beating their addiction, abusers are encouraged to change their environment, avoiding drug-using friends and even moving to a new community if possible. While those with deep pockets may have access to the best treatment programs money can buy, they also have the financial wherewithal to keep supporting a drug habit and therefore are not immune from the dangers of relapse. Celebrities such as Downey and Strawberry are ``like kids in a candy store,'' Koob said. It isn't realistic ``to ask someone to stop taking cocaine when they have bowls of it right in front of them.'' Emotions such as anger, anxiety and depression can also cause a recovering addict to seek out drugs. Often, former users don't realize how powerful that one little taste of drugs can be. ``There's a perception you have more control than you do,'' said Marlatt, who has studied relapse prevention. The stakes are high as California gears up for its change in dealing with drug users. The state's new treatment programs, with an estimated budget of $660 million over five years, are likely to give doctors and researchers more insight into treating drug offenders and reducing relapse rates. Many in the field believe that a minimum of three months of treatment is imperative. One or two years, they say, is best. Proposition 36 allows eligible offenders to receive up to one year of drug treatment and up to six months of follow-up care. If the state can show that its new drug treatment plan works, ``it would change the whole national picture,'' Marlatt said. ``So it's a big one.'' - --- MAP posted-by: Andrew
