There are two routes typically applied to a cognitive approach to substance abuse: tracking the thoughts that pull patients to addiction and tracking the thoughts that prevent them from relapsing. Behavioral techniques have the widest application in treating substance related disorders. Behavioral psychologists can use the techniques of “aversion therapy,” based on the findings of Pavlov's classical conditioning. It uses the principle of pairing abused substances with unpleasant stimuli or conditions; for example, pairing pain, electrical shock, or nausea with alcohol consumption.[37] The use of medications may also be used in this approach, such as using disulfiram to pair unpleasant effects with the thought of alcohol use. Psychologists tend to use an integration of all these approaches to produce reliable and effective treatment. With the advanced clinical use of medications, biological treatment is now considered to be one of the most efficient interventions that psychologists may use as treatment for those with substance dependence.[37]

In a survey of treatment providers from three separate institutions, the National Association of Alcoholism and Drug Abuse Counselors, Rational Recovery Systems and the Society of Psychologists in Addictive Behaviors, measuring the treatment provider's responses on the "Spiritual Belief Scale" (a scale measuring belief in the four spiritual characteristics of AA identified by Ernest Kurtz); the scores were found to explain 41% of the variance in the treatment provider's responses on the "Addiction Belief Scale" (a scale measuring adherence to the disease model or the free-will model of addiction).[30]
Physical dependence on a drug can cause serious withdrawal symptoms if a person suddenly stops using the substance or severely reduces the dose. The withdrawal process itself can be uncomfortable and dangerous. Some of the classic signs of withdrawal include tremors, cold sweats, involuntary movements (e.g., jerking, twitching, or shaking), nausea and vomiting, muscle cramps and bone pain. Because withdrawal can be dangerous, proper medical detox can be a life-saving step in recovery. Sunrise Foundation Rehabilitation Center in India near Mumbai
To feel good. Drugs can produce intense feelings of pleasure. This initial euphoria is followed by other effects, which differ with the type of drug used. For example, with stimulants such as cocaine, the high is followed by feelings of power, self-confidence, and increased energy. In contrast, the euphoria caused by opioids such as heroin is followed by feelings of relaxation and satisfaction.

Hospitalization Rehab, often known as a Partial Hospitalization Program, allows addicts to check into a treatment center or hospital for a certain number of hours each week. This is most similar to an outpatient rehab center, in that individuals will return to their home after their treatment program. However, in an outpatient clinic, patients may check in briefly and then leave.

Withdrawal can begin soon after the cessation of drug use and will likely peak in intensity in the first 24 to 48 hours. If severe withdrawal is left unchecked, in some instances it can be fatal. Anyone experiencing the symptoms of withdrawal should be under a doctor’s care, and for drug addicts entering treatment medical detox is often required before therapy for addiction can begin.

"The most robust finding in the study is that those receiving any medication did much better than those who received no pills at all," says Professor Barbara Mason, Scripps Research Institute, and an author of the study. "This should be a wake-up call. With less than one percent of those seeking help for alcohol dependence receiving a prescription, medication is underutilized. Medication for alcoholism can offer patients an advantage for their recovery, especially in a real-world setting." Introduction To The 12 Steps - The Owl's Nest Recovery Community
Many addicts feel the need to lie about their problems, whether it be to themselves or family members. A group therapy session creates a support mechanism in which patients are encouraged to open up about their issues in a safe setting. Since every member of the group understands that the patient is going through, there is no need for the patient to hide anything or lie.
