• Delayed discounting, the willingness to put off present gratification in the interest of a bigger long-term reward. Addicts always take the immediate reward.

• Reflection impulsivity, a measure of how much information is required to make a decision. Addicts typically act without processing all the available information.

• Intentional action, the ability to consciously stop a behavior that has become automatic.

To measure this, NIDA researchers had addicts watch a screen and push one of two buttons, according to whether a light has flashed on the left or right side—except when the light was accompanied by a tone. After several rounds, pushing the button becomes an automatic response that has to be overridden consciously, and addicts were much less able to do this than non-addicts. As scientists have known since the 1980s, the neurons that control movement are activated even before a person is aware of the intention. Now researchers have identified the part of the brain—the fronto-median cortex—that is activated when someone stops himself from executing such automatic behaviors. This is as close as we have got to finding the seat of willpower in the brain. Put an addict in an fMRI machine, and you can observe reduced activity in the fronto-median cortex. But a drug called Provigil, which is ordinarily used to treat narcolepsy, stimulates that part of the brain and is now being tested as a treatment for amphetamine addiction. "The idea that we can restore 'self-control' or 'free will' with medication is a very, very exciting one," says Vocci of NIDA. "It could be paradigm shifting. But we need more studies to see how consistently that impacts recovery."

That is a useful caution; these drugs are new and their mechanisms are still only partially understood. The brain has a way of resisting attempts to tinker with its chemistry. The discovery in 1960 that Parkinsonism was caused by a deficiency of dopamine quickly led to the use of synthetic dopamine precursors, such as L-dopa, which relieved the symptoms at first, but were not the long-term cure patients had hoped for.

A more straightforward approach to treating, or preventing, addiction is to block the action of the drug directly. If it doesn't feel good, the thinking goes, you won't do it. Naltrexone, a pill that has been around for a decade, works that way against alcohol, but an addict intent on getting high can just skip his dose. The solution to that problem is Vivitrol, a longer-lasting, injectable form of Naltrexone, which came on the market in 2006. Vivitrol, the drug Annie Fuller took, does not enhance self-control or stop the craving for liquor, but it does block liquor's effects. The day Fuller got her shot, her leg swelled to twice its normal size. The swelling subsided a day or two later, but the next few weeks were a torment of sweating, shaking, vomiting and tears—side effects that came from both Vivitrol and alcohol withdrawal. At times she couldn't walk and needed help to use the bathroom. The only thing that kept her from drinking was the knowledge that she could not get drunk. "The shot just took the relapse option off the table," she says. She got the same injection every month for the rest of the year, suffering a little less each time, and she is now off the medication and sober.

    Addiction=$$$$$$. Our wonderful medical professions could not function without problems created by their own medications. Man made substances do more harm than good, or else why are there so many disclaimers in drug ads?
    Feel worse, and/or have other symptoms that require more treatment? What a shyster game.
    As was said above, people like drugs. It's the moderation of them that is an issue. How many heroin/cocain/meth addicts would start smoking just pot if legal? Most every one.

    Well very well thought out and backed by numerous psychiatric institutions and research centres , who gain funding for looking for complex answers to simple questions. Addiction is an ethical issue, not a medical one. People use drugs because they like them. This is illustrated by the famous philosopher / scientist Occam (Occam???s razor) The principle states that the explanation of any phenomenon should make as few assumptions as possible, eliminating those that make no difference in the observable predictions of the explanatory hypothesis or theory . Alternatively, put more simply the simplest explanation is normally the correct one.
    My own experience validates this. In 2006, I initiated a self-induced withdrawal off 195 mg methadone of which 150mg was in injectable form. I had been on this maintenance regime for 16 years and the dose and type of opiate prescribed altered over the years, the only consistency was the escalation of the prescription. In addition I smoked over half an ounce on cannabis and drank in excess of 12 bottles of strong larger a day. I did not reduce or taper off any of the named substances, this detox was done alone and without medical or family support. It is now over 22 months and I am still opiate free do not smoke cannabis, but drink socially on occasions. I hope to share this experience and the strategies employed, to give others the hope and belief that addiction is not a disease and the only power it has over you is the power you give it.

    ¨From a neurological viewpoint, addictions are the result of the brain chemistry dysfunction that came about as a result of unbalanced excitatory and inhibitory processing in the neurons. Neurons communicate with each other by firing electrical signals which are then translated into chemical signals called neurotransmitters. The neurotransmitter of addiction is dopamine, which is designed to maintain pleasant mood states. When dopamine falls below acceptable levels this causes the individual to experience sensations of 'withdrawal' as it is called in the psychiatric field. Withdrawal charges the addict to find ways to increase dopamine levels perhaps by taking illegal substances to compensate for the shortfall. As the substance wears off a new cycle of withdrawal and addiction begins....¨ taken from the book tangledsynapses, by Ignacio Sanabria, Neuroscience researcher, www.tangledsynapses.com

    However, there is hope for the addicts, beside drug therapy, that in some cases is warranted, as the brain pleasure centers must, somehow be balanced again.

    The latest research points out that a GRUELING EXERCISE REGIME is the best therapy there is for addiction. The exact mechanism as to why exercise helps with brain chemistry dysfunction is under research, but it points out to the release of endorphins, adrenaline, among others, that in turn triggers the brain pleasure centers such as the LAPX axis, dopamine, serotonin and other neurotransmitters to secrete the necessary chemical compounds to contribute to balance brain dysfunction.
