The Drug Evaluation and Classification (DEC) program is used by police agencies to identify drivers impaired because of drug use and to determine the class(es) of drug causing the impairment. The primary goal of this study was to determine the validity of the DEC evaluation in predicting whether

Rapid, reliable, sensitive, qualitative, and quantitative methods using small urine volumes (0.2-0.5 mL) were developed primarily for confirmation of marijuana, cocaine, benzoylecgonine, ecgonine methyl ester, morphine, codeine, amphetamine, methamphetamine, and phencyclidine. Using capillary gas

Aim: Marijuana use has been postulated to modulate opioid use, dependence and withdrawal. Broad target drug testing results provide a unique perspective to identify any potential interaction between marijuana use and opioid use. Materials & methods: Using a dataset of approximately

Statistics show that the prevalence of crack cocaine use and embalming fluid and phencyclidine (PCP)-laced cigarettes or marijuana sticks, commonly referred to on the street as "fry" or "wet" is a problem; however, the relationship between these substances of abuse and concurrent polydrug use is

Various basic esters of nitrogen (2) and carbocyclic (3 and 4) analogs of cannabinoids were synthesized using dicyclohexylcarbodiimide in methylene chloride. The compounds in the three series werw studied in selected pharmacological tests in mice, rats, dogs, and cats. It was shown that making the

Cannabinoids are medically interesting, but the available data are still weak scientifically and overwhelming anecdotally. In the management of pain, cannabinoids have been shown to have antinociceptive properties in animal models of pain, with non-opiate mechanisms appearing to predominate. A

A case is presented involving a young woman on several illicit drugs (heroin, cocaine and cannabis) as well as two medications and a solvent used for their anesthetic and narcotic properties: thiopental, ketamine and chloroform. This complex drug use was supported by hair analysis over a 10.5 cm

Testing for drugs of abuse in urine is commonplace in emergency departments and neonatal units. However, the clinical sensitivity of immunochemical screening methods is limited by the threshold concentrations used to distinguish between positive and negative specimens. Immunochemical screening

BACKGROUND Undisclosed use of illicit drugs and prescription controlled substances is frequent in some settings. The aim of the present study was to estimate the reliability of self-reported use of amphetamine, barbiturates, benzodiazepines, cannabinoids, cocaine, methadone, and opiates among

Recent survey research has documented important increases during the 2000s in the misuse and abuse of several prescription drugs (Vicodin, Percocet, Codeine, Dilaudid, Xanax, Klonopin, Valium, Ativan, Adderall, Ritalin, among others). This article focuses upon the patterns of pill use and misuse

Experimental cough was elicited in pentobarbital-anesthetized cats by either electrical stimulation of the superior laryngeal nerve or by mechanical stimulation of the tracheal mucosa. Intravenous administration of delta9-tetrahydrocannabinol (THC) effectively reduced the amplitude of the cough

OBJECTIVE While the United States has been experiencing an opioid epidemic, 29 states and Washington DC have legalized cannabis for medical use. This study examined whether state-wide medical cannabis legalization was associated with reduction in opioids received by Medicaid

The present paper describes a sensitive method developed in our laboratory for the simultaneous analysis of opiates (morphine, codeine and monoacetylmorphine), cocainis (cocaine and benzoylecgonine) and cannabinoids (delta 9-tetrahydrocannabinol and 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic

Background: In the wake of the rising rate of prescription opioid misuse, there has been increased public health interest in the possibility that cannabis might help to curb or prevent opioid use disorder. Previous studies were limited to
