Abstinence syndrome withdrawal treatment

Tolerance to the effects of marijuana clearly exist even though chronic users have described a reversed tolerance and claim that smaller doses of the drug are necessary to produce the desired effects. This effect is probably related to the manner of use and the expectations of the user. Chronic, high-dose cannabis users may experience an abstinence or withdrawal syndrome on abrupt discontinuation of use. Signs and symptoms include irritability, restlessness, nervousness, weight loss, insomnia, and rapid eye movement (REM) rebound. Onset of this syndrome is several hours after the last dose, and it lasts 4 to 5 d. Because withdrawal is not life-threatening, treatment involves little more than supportive therapy with short-term, low doses of benzodiazepines. 

The neonatal abstinence syndrome occurs in 30-80% of infants whose mothers have taken opiates during pregnancy. The incidence is higher in those whose mothers have a history of opioid dependence and are taking methadone maintenance than in those who are taking methadone for chronic pain (39). The methadone blood concentration may be a useful predictor of the likelihood of severe withdrawal requiring treatment, but clinical assessment by a standardized scoring system is still required to determine the need to treat the neonatal abstinence syndrome (40).

Fetotoxicity Exposure to opioids in utero can lead to the development of the neonatal abstinence syndrome, especially in infants born to mothers who have misused these drugs. Neonatal abstinence syndrome in neonates bom to mothers taking treatment has been investigated in 68 neonates. Pre-delivery higher doses of maternal methadone were associated with an increased incidence of treatment for withdrawal and with longer episodes of neonatal abstinence syndrome. There was a dose-response relationship— for every 1 mg increase in last maternal methadone dosage before delivery, an extra 0.18 days of infant treatment for neonatal abstinence syndrome were required furthermore, breastfeeding reduced the duration of neonatal abstinence syndrome by 7.76 days [261. 

The immediate concern in the treatment of alcoholics is detoxification and management of the ethanol withdrawal syndrome. Once the patient is detoxified, longterm treatment requires complete abstinence, psychiatric treatment, family involvement, and frequently support from lay organizations such as Alcoholics Anonymous. 

The treatment of alcohol withdrawal incorporates general supportive measures, as well as management of specific symptoms. Supportive measures include abstinence from alcohol, ample rest, adequate general nutrition, and reality orientation. It is important to treat the syndrome vigorously and, when appropriate, to prevent it by using sufficient doses of medication. 

Psychiatric symptoms are very common in alcohol intoxication and withdrawal, but studies by Schuckit show that most of these symptoms improve greatly within one to four weeks of abstinence and are likely to abate over several months (Brown and Schuckit 1988 Schuckit, Irwin, and Brown 1990). The three diagnoses associated with increased risk of alcoholism are schizophrenia, mania, and antisocial personality disorder. As a depressant, alcohol tends to produce depressive symptoms during intoxication and anxiety symptoms during withdrawal and abstinence. These syndromes often mimic major depression or an anxiety disorder, but they will usually resolve within two weeks of abstinence and do not require prolonged treatment.
