Determination of epidemiological characteristics of addicts treated in drug addiction clinics in Kabul.

According to the Afghanistan Ministry of Health, 3.5 million people use drugs, 2.4 million of which are regular users. In this cross-sectional study, it was aimed to determine epidemiological characteristics of addicts in a treatment center in Kabul. Eight hundred people were included. Statistical analysis was done with SPSS 22.0. The average age was 30.74 years, 88.9% were male, and 50.6% were married. Further, 35.9% have never been trained, 60.5% of participants were living in urban areas, 62.8% were refugees, 17.5% were unemployed, and 30.3% of them had monthly income below 147.1 USD. The average age of starting substance use was 19.9 years. "Friendship environment" was the leading reason to start (36.6%), followed by "reduce troubles" with 22.3%. The most preferred substance was cannabis (46.0%), followed by opium (25.3%) and heroin (17.0%). Heroin was the most commonly used substance lifelong (87.1%), followed by cannabis (66.3%) and opium (65.5%). When compared to individuals younger than 18, heroin use rates were 3.52 times higher in the 18-to-30 age range, 5.49 times higher in the 31-to-45 age range, and 1.86 times higher in urban residents than rural. Cannabis use was 12.24 times more among men than women, 2.79 times higher among divorced or widowed individuals than singles, 1.68 times higher among refugees than non-refugees, and 2.26 times higher among drug traffickers than non-traffickers. Opium use was 1.63 times higher for refugees than non-refugees and 3.24 times higher in those who worked in drug fields than those who did not. Periodic assessment of prevalence of drug use and the establishment of drug use monitoring systems are recommended.

Laser-induced fluorescence spectroscopy of plant-based drugs: Opium and hashish provoking at 405 nm.

Here, the fluorescence properties of some plant-based drug samples are characterized using a coherent excitation source at 405 nm. The laser-induced fluorescence (LIF) spectroscopy is examined to analyze opium and hashish. In order to improve traditional fluorescence methods for better analysis of optically dense materials, we have proposed five characteristic parameters based on solvent densitometry assay as the fingerprints of drugs of interest. The signal emissions are recorded in terms of various drug concentrations, such that the best fitting over experimental data determines the fluorescence extinction (α) and self-quenching (k) coefficients according to the modified Beer-Lambert formalism. The typical α value is determined to be 0.30 and 0.15 mL/(cm∙mg) for opium and hashish, respectively. Similarly, typical k is obtained 0.390 and 1.25 mL/(cm∙mg), respectively. Furthermore, the concentration at max fluorescence intensity (Cp) is determined for opium and hashish to be 1.8 and 1.3 mg/mL, respectively. Results reveal that opium and hashish benefit their own characteristic fluorescence parameters to discriminate those illicit substances promptly using the present method.

Drug offenses in the Tokyo Metropolitan Area: Trends for 2016-2018.

In Japan over the past few years, approximately 13,000 individuals were arrested for drug offenses each year. It is useful to know the trends in drug offenses, in order to devise the most effective countermeasures and addiction treatment programs. Herein, we have revealed the trends in drug offenses in the Tokyo Metropolitan Area. This report was researched the number of individuals arrested for drug offenses in Tokyo during the 3-year study period 2016-2018. The drugs are classified into the six categories: stimulants, narcotics, psychoactive drugs, opium, cannabis, and designated substances. We also calculated the percentages of individuals arrested for various drug offenses based on these six categories. Approximately 86% of the arrests for drug offenses in Tokyo during the 3-year period were for stimulants or cannabis. A higher percentage of individuals were arrested for stimulants, but the percentage of individuals arrested for cannabis increased each year. Given the percentage of individuals arrested for designated substances or narcotics, preventive measures for drug offenses involving stimulants and cannabis should be promptly implemented. Further campaigns to prevent drug offenses and public lectures are also needed. Public education must be provided to prevent drug offenses involving designated substances and narcotics.

Narcotic use in southeast Asia and afterward. An interview study of 898 Vietnam returnees.

From all US Army enlistees leaving Vietnam in September 1971, a random sample of 943 men was selected. Of these, 470 represented a "general" sample of all enlistees returning at that time, and 495 represented a "drug positive" sample whose urine samples had been positive for opiates at the time of departure. We attempted to locate and personally interview all of the men in the samples. Results indicate that before arrival, hard drug use was largely casual, and less than 1% had ever been addicted to narcotics. In Vietnam, almost half of the general sample tried narcotics and 20% reported opiate addiction. After return, usage and addiction essentially decreased to pre-Vietnam levels. We discuss the use of nonnarcotic drugs, predictors and correlates of drug use in the samples, and the relationship of drugs to post-Vietnam social adjustment.

Patterns of illicit drug use in the Army.

The authors collected detailed histories of illicit drug use in the Army in individual interviews with a stratified random sample of 262 enlisted men at six military posts across the United States. Approximately half of the sample (N equals 128) were classified as drug users; 90 of these individuals were identified as career multiple-drug users. Most of these subjects used a variety of drugs in frequently changing patterns. The authors emphasize the individualistic nature of drug use and question the appropriateness of an addiction model for most users of illicit drugs.

Prolonged cataleptogenic effects of potentized homoeopathic drugs.

The four homoeopathic drugs, Gelsemium, Cannabis Indica, Graphites and Agaricus Muscarius, administered orally in 30th and 200th potencies on white rats, enhanced restraint-induced catalepsy in a similar manner to the two standard drugs pilocarpine and haloperidol (IP injection at 5 mg/kg). All the drugs tested differed from each other in the duration of cataleptogenic effect, which was more prolonged with Cannabis, Graphites and Agaricus than with Gelsemium and the two non-homoeopathic drugs used. The 200th potency of any homoeopathic drug tested acted longer than its 30th potency.

Cannabis condemned: the proscription of Indian hemp.

AIMS: To find out how cannabis came to be subject to international narcotics legislation. METHOD: Examination of the records of the 1925 League of Nations' Second Opium Conference, of the 1894 Report of the Indian Hemp Drugs Commission and other contemporary documents. FINDINGS: Although cannabis (Indian hemp) was not on the agenda of the Second Opium Conference, a claim by the Egyptian delegation that it was as dangerous as opium, and should therefore be subject to the same international controls, was supported by several other countries. No formal evidence was produced and conference delegates had not been briefed about cannabis. The only objections came from Britain and other colonial powers. They did not dispute the claim that cannabis was comparable to opium, but they did want to avoid a commitment to eliminating its use in their Asian and African territories.

The non-medical use of psychoactive substances among male secondary school students in Egypt: an epidemiological study.

The paper reports on an epidemiological study of the non-medical use of psychoactive substances by secondary school male students in Greater Cairo. The main aim of the study was to provide factual answers to the questions: (1) How prevalent is drug abuse among male school students? (2) What are the psychoactive substances most commonly used? (3) What sociopsychological variables are meaningfully associated with the use of substances?

A Swedish drug abuse warning network.

During the period June 1971-December 1976 a total of 592 consecutive admissions to a Drug Addiction Clinic were asked which drugs they had been taking since their first contact with the illegal drug market. Nine drugs belonging to the opiate group, five different amphetamines, five hallucinogens, cocaine and cannabis were mentioned and the patients were asked to specify which year or years they had self-administered any of the drugs mentioned. No attempts were made to quantify the individual drug consumption. The amphetamines and cannabis dominated in the mid sixties, but from then on recorded used of these drugs declined. From 1965 there was a constant increase in the reported use of opiates up to a maximum of 55 per cent of the patients in 1976. The opiates seem to have been introduced on to the market in the order of increasing potency. Morphine base replaced raw opium in the early seventies but was later succeeded by heroin. Hallucinogens, except for a short period around 1969 when 11 per cent of our patients mentioned them, never seemed to reach important levels. A small but growing proportion of our patients have mentioned use of cocaine in the seventies.

Recent progress in the neurotoxicology of natural drugs associated with dependence or addiction, their endogenous agonists and receptors.

Nicotine in tobacco, tetrahydrocannabinol (delta 9-THC) in marijuana and morphine in opium are well known as drugs associated with dependence or addiction. Endogenous active substances that mimic the effects of the natural drugs and their respective receptors have been found in the mammalian central nervous system (CNS). Such active substances and receptors include acetylcholine (ACh) and the nicotinic ACh receptor (nAChR) for nicotine, anandamide and CB1 for delta 9-THC, and endomorphins (1 and 2) and the mu (OP3) opioid receptor for morphine, respectively. Considerable progress has been made in studies on neurotoxicity, in terms of the habituation, dependence and withdrawal phenomena associated with these drugs and with respect to correlations with endogenous active substances and their receptors. In this article we shall review recent findings related to the neurotoxicity of tobacco, marijuana and opium, and their toxic ingredients, nicotine, delta 9-THC and morphine in relation to their respective endogenous agents and receptors in the CNS.

Method comparison of EMIT II and online with RIA for drug screening.

The newest formulation of the EMIT assay for drugs of abuse, EMIT II, and a new immunoassay, OnLine, using the kinetic interaction of microparticles in solution methodology, were evaluated for marijuana, cocaine, opiates, barbiturates, and phencyclidine. Both types of immunoassays were performed on an Hitachi 717 analyzer. Calibration curves, the degree of separation between negative and cutoff calibrators, precision, probability of carryover from positive to negative samples, and overall ease and speed of analysis were evaluated. EMIT II and OnLine were compared with RIA tests for the five drugs to determine each assay's ability to detect samples which confirm positive by GC/MS. The RIA and OnLine marijuana tests detected > 99% of confirmed positive samples while EMIT II detected about 90%. All three immunoassays performed equivalently for cocaine and opiates, each assay detecting at least 98% of positives. Barbiturates showed the greatest disparity with OnLine detecting 96%, EMIT II 85%, and RIA 79% of confirmed positive samples. Too few phencyclidine positive samples were detected for a method comparison study. The fully automated EMIT II and OnLine assays are preferable for a variety of reasons to our laboratory's current semi-automated RIA tests for large volume urine testing. The immunoassays offer comparable performance for some drugs but not for others.

Medical treatment of the adolescent drug abuser. An opportunity for rehabilitative intervention.

Illnesses related to both the pharmacologic properties of abused substances and their methods of administration often bring the teenager to medical attention and may provide sufficient motivation for the adolescent to seek help beyond the acute problem. Successful treatment of an overdose reaction, an abstinence syndrome, or any other medical complication of drug abuse may give the physician a unique opportunity to begine further evalution for future care.

An exploratory study on depression in Iranian addicts.

For the purpose of measuring the degree of depression among drug addicts in Iran, the Beck Depression Inventory was administered to 50 addicts, 46 depressed non-addicts, and 48 normal controls. Statistical comparison of the BDI for the three groups yielded a significant difference between the addicts and the controls, whereas the difference between the addicts and the depressed non-addicts was not significant; this indicates that depression is one of the clinical symptoms of drug addiction in Iran.

[Pharmacopsychoses during drug addiction]. / Les pharmacopsychoses au cours des toxicomanies

Widespread use of certain drugs (amphetamines, L.S.D., hypnotics) in France, allowed us to observe more than 200 cases of acute or chronic psychoses among addicts. Sometimes these are transitory outburst but the occurrence of a delusional psychosis with long range evolution raises a difficult diagnosis problem in relation to functional psychoses. The emphasis should be put on respective roles of the drug and of a predisposed mental state. Circumstances of beginning, apparently direct relationship between drug taking and pathological symptoms, therapy efficiency, absence of earlier pathological traits (as in many of our patients) and relapse when intoxication starts again, are in favour of a pharmacological origin of the troubles.

[Serum immunoglobulins of drug addicts and alcoholics]. / Syvorotochnye immunoglobuliny u bol'nykh narkomaniei i alkogolizmom.

In 34 patients with polyaddiction, 30 with hashishaddiction and 10 opiateaddiction and in 6 patients with chronic alcoholism the author studies the content of serum immunoglobulins of class A. M. G. The studies established that the content of IgA is increased in patients with polyaddiction, chronic alcoholism. An increase of IgA in the blood serum is marked in hashishaddiction, opiateaddiction and chronic alcoholism and its increase in opiateaddiction and polyaddiction. The character of changed serum IgM depends upon the type of addiction: it is increased in opiateaddiction, decreased in hashishaddiction and chronic alcoholism and not changed in polyaddiction.

Opiate use, treatment, and harm reduction in Afghanistan: recent changes and future directions.

Afghanistan leads global opium and cannabis production, amidst concerted efforts to improve the country's infrastructure. In this commentary, the evidence base for drivers of increased drug use in the context of deteriorating security is presented, government, donor, and civil society responses to date are described, and key areas for health policy response are summarized. Opiate use in Afghanistan shows disturbing trends: multiple substances are accessible at low cost and frequently used in combination, and injecting use has become more common. Pressures from both donor and governmental sectors have compromised innovations in programming. Further, civil unrest and resultant displacement have created challenges for programme implementation. Afghanistan urgently needs a well-funded, sustainable, comprehensive, and inclusive programme of drug dependency treatment, aftercare, and harm reduction services, as well as realistic, effective, and culturally salient primary prevention programmes. To date, drug dependence is not a prioritised issue, current programmes are under-resourced, and the continuum of care has a narrow scope generally limited to treatment. Unless this issue is addressed, the next generation of Afghans is poised to become a casualty of the opiate industry.
