Interventions depend on the complexity of the problem.When the person has mild substance abuse problem, education might be enough. Some people might need short cognitive behavioral therapy.
When the patient is complaining of dependence then a more sophisticated help is needed which might include hospital admission to treat withdrawal syndrome that might appear after abstinence, in addition to many other psychosocial interventions and a long period of continuous care to prevent relapse which is very common.
The first stage of treatment after abstinence is called detoxification.
Treatment of substance abuse
Treatment of withdrawal syndrome can be done as an outpatient treatment , but many times it is preferred to put the patient under direct supervision in an addiction treatment facility.
Withdrawal symptoms can be severe and sometimes dangerous.
Treatment can be accomplished by many ways depending on the type of the addictive substance; it might be done by gradually decreasing the substance like in addiction on benzodiazepines, or by giving a medication that has similar pharmacological effects and then decreasing it gradually like giving chlordiazepoxide to treat withdrawal of alcohol.
Some substances can be treated by giving a medication that blocks the withdrawal by an effect on the receptors like naltrexone which is given to treat withdrawal of opiates and alcohol.
Some withdrawal symptoms are treated according to type of distress caused like antispasmodics for abdominal pain and diarrhea of opiate withdrawal, analgesics for pain , hypnotics for sleep problems ,and so on.
Detoxification
Treatment of substance abuse in not an easy task
Quitting the use of a substance needs lots of changes in life style, relationships, and behavior. This cannot be accomplished without a professional help. This help can be done by counseling , self-help groups, family and social support.Recovery of the brain might take a year or so during which the possibility of relapse is high.
Relapses are common and do not mean failure of treatment.
Family is very important part of treatment.
Counseling includes individual and group therapy sessions.
Interventions include: relapse prevention, CBT, life skills, etc.
Medications for maintenance are also available for some types of addiction like disulphiram and acamprostate for alcohol, and methadone for opiates.
Treatment of co-morbid psychiatric problems like depression and anxiety disorders is important.
Psychosocial intervention
Comprehensive treatments
Primary : dealing with causes: improvement of life circumstances, education, employment, good parenting, legislations ( limit the use and decrease availability of substances)
Secondary : treatment of substance abuse problems
Tertiary : decrease complications
Harm reduction : when people are unable to quit the use of substances. What to do?
Prevention
Some patients are unable or unwilling to abstain from the use of substances.
Those patients can be helped by many ways:• Education about safe sex
• Encouragement to use a safe way of injecting drugs which will decrease possibility of acquiring infections like hepatitis and HIV ,through needle exchange programs
• Opiate substitution therapy(OST): in which heroin is substituted by much less harmful opiates like methadone and piprenorphine.
Harm reduction
Substance abuse problems are very common
They have a great impact on the individuals, families, and community.Etiology is multi-factorial
Substance abuse problems should be considered in the differential diagnosis of any psychiatric disorder
Treatment is complicated and associated with high rates of relapse
We should deal with these problems as mental health problems (illnesses )
