Drug testing in substance abuse treatment programs is focused on urine analysis of parent drugs and major metabolites. Huestis reported that serial monitoring of the major urinary cannabinoid metabolite (delta9-THC-COOH)-to-creatinine ratios in paired urine specimens (collected at least 24 hours

A previously recommended method for detecting new cannabis use with creatinine-normalized 11-nor-9-carboxy-Delta(9)-tetrahydrocannabinol (THCCOOH) urine concentrations in periodically collected specimens for treatment, workplace and judicial drug testing applications is refined by considering the

The objective of this study was to compare urinary excretion patterns of two cannabinoid metabolites in subjects with a history of chronic marijuana use. The first metabolite analyzed was nor-9-carboxy-delta9-tetrahydrocannabinol (delta9-THC-COOH), the major urinary cannabinoid metabolite that is

Variability in urine dilution complicates urine cannabinoid test interpretation. Normalizing urine cannabinoid concentrations to specific gravity (SG) or creatinine was proposed to account for donors' hydration states. In this study, all urine voids were individually collected from eight frequent

Up to 25% of hospitalized patients in a psychiatric department exhibit troubles linked to cannabis use. Weaning patients with psychiatric disorders off drugs of abuse requires specific care to improve their clinical outcome. The present study aims to develop a predictive model of urinary excretion

To assess whether symptoms of depression change when people with multiple sclerosis (pwMS) discontinue cannabis use, 40 cognitively impaired pwMS who smoked cannabis almost daily were randomly assigned to either a cannabis continuation (CC) or cannabis withdrawal (CW) group. Both groups were

BACKGROUND Changes in cannabis regulation globally make it increasingly important to determine what predicts an individual's risk of experiencing adverse drug effects. Relevant studies have used diverse self-report measures of cannabis use, and few include multiple biological measures. Here we aimed

Gender differences in cannabis use and cannabis use disorder have been established. Regarding treatment, some evidence suggests that women are less responsive, though the mechanisms are not well understood. Motivation to change and self-efficacy are associated with better outcomes overall, and may

The aim of this study was to evaluate whether physical exercise or food deprivation may increase cannabinoid levels in serum or urine in abstinent chronic cannabis users. The study took place in a drug detoxification ward parallel to study participants receiving treatment. Six chronic, daily

The use of synthetic cannabinoids (SCBs) is associated with many severe adverse effects that are not observed with marijuana use. We report a unique case of a patient who developed rhabdomyolysis and acute kidney injury (AKI) requiring dialysis after use of SCBs combined with quetiapine. Causes for

Increases in urine drug concentration that result from changes in urinary output may be mistakenly interpreted as new drug use rather than carryover from previous drug exposure. Normalization of drug excretion to urine creatinine concentration reduces the variability of drug measurement attributable

Verification of abstinence from cannabinoid use after initial identification requires documentation of falling quantitative levels of urinary 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) over an extended time period. We present a case in which normalization of quantitative

Activating type 1 cannabinoid (CB1) receptor decreases the particle size of high-density lipoprotein (HDL) and inhibits reverse cholesterol transport (RCT). This study examined whether marijuana (MJ) use is associated with changes of RCT, and how the latter is associated with mitochondrial function

The agreement between self-reported cannabis abstinence with urine cannabinoid concentrations in a clinical trials setting is not well characterized. We assessed the agreement between various cannabinoid cutoffs and self-reported abstinence across three clinical trials, one including contingency
