Cannabidiol (CBD) is widely used and believed to be non-intoxicating, lacking acute performance effects (e.g., non-impairing). However, a synthesis of data has not evaluated this. This meta-analysis synthesized from controlled human laboratory studies that if CBD use impairs performance. Performance on objective subjective measures cognitive psychomotor function were as markers for potential changes impairment. Studies identified through systematic database searches. Adult clinical trials measuring (within 0-8 h administration) included. The primary outcome was the peak mean difference in between placebo. A secondary analysis utilizing delta-9-tetrahydrocannabinol (Δ9-THC) positive control comparison completed.

Abstract Background Canada legalized recreational cannabis in 2018, and one of the primary objectives Cannabis Act was to protect youth by reducing their access providing public education. has highest prevalence use worldwide, particularly among young adults under age 25. is linked with many adverse effects for including psychosis, anxiety, depression, respiratory distress, cannabinoid hyperemesis syndrome, impaired cognitive performance. Despite high evolution policies globally, significant knowledge research gaps remain regarding adult use. The aim this scoping review map extent, nature, range evidence available on since its legalization, order strengthen policies, services, treatments, training, education strategies. Methods Using a framework developed Arksey O’Malley, along PRISMA-ScR guidelines, we conducted rigorous search five academic databases: MEDLINE, Embase, APA PsycINFO, CINAHL Web Science Core Collection. We included empirical studies that collected data after legalization (October 2018) focused or < 30. Two reviewers independently screened articles two stages extracted relevant information from meeting inclusion criteria. Results Of 47 our criteria, 92% used quantitative methods, 6% were qualitative, 2% mixed-methods approach. Over two-thirds (68%) secondary data. These categorized into six focus areas: (1) prevalence, patterns, trends, (2) cannabis-related injuries emergency department (ED) visits, (3) rates patterns during pandemic, (4) perceptions use, (5) prevention tools, (6) offenses.

Cannabis edibles are an increasingly popular form of cannabis consumption. Oral consumption has distinct physiological and behavioral effects compared with injection or inhalation. An animal model is needed to understand the pharmacokinetics oral in rodents as a for human edible use.Adult male female C57BL/6 mice received single dose commercially available oil (5 mg/kg Δ⁹-tetrahydrocannabinol [THC]) by gavage. At 0.5, 1, 2, 3, 6 hours post exposure, plasma, hippocampus, adipose tissue were collected THC, 11-OH-THC, THC-COOH measures.We report delayed time peak THC 11-OH-THC concentrations brain, tissue, which consistent studies. We also found sex differences tetrad: (1) had hypothermic effect consumption, was not present males; (2) females stronger catalepsy than (3) males less mobile following whereas showed no difference locomotion but anxiogenic at 3 exposure; (4) displayed longer-lasting antinociceptive cannabis.Oral translationally relevant administration that produces similar vaping thus should be considered viable approach examining moving forward. Furthermore, given strong metabolism cannabis, these factors carefully when designing studies on cannabis.

Given the popularity and ease of single-item craving assessments, we developed a multi-item measure compared it to common assessments in an ecological momentary assessment (EMA) context. Two weeks EMA data were collected from 48 emerging adults (56.25% female, 85.42% White) who frequently used cannabis. Eight items administered, multilevel factor analyses identify best fitting model. The resulting scale’s factors represented purposefulness/general desire emotionality/negative affect craving. Convergent validity was examined using measures craving, cannabis use disorder symptoms, frequency use, cue reactivity, negative affect, impulsivity. scale associated with cue-reactivity impulsivity, subfactors existing measures.

Given diversified cannabis products, we examined associations between consumption methods and risk perception of smoking 1–2 times a week. Using the 2022 U.S. National Survey on Drug Use Health data (N = 12,796 past-year adult users; M 6127 F 6669), used multinomial binary logistic regression models. Smoking was most prevalent method, followed by eating/drinking, vaping, dabbing. One-half users reported no perceived week, 37.5% slight risk, 9.2% moderate 2.9% great risk. Those with or had lower likelihood using 4+ (e.g., RRR 0.40, 95% CI 0.20, 0.77 for perception).

Considerable differences in the types of cannabis products, methods use, social norms and cultures legal climates surrounding use exist among regions, resulting distinct contexts. Research examining accounting for these contextual is crucial to further understanding disorder, developing refining context sensitive strategies prevention, treatment harm reduction. The past two decades have seen increased legalization recreational across globe, prevalence emerging evidence cannabis-related harms [1]. We argue that precisely how impacts people who cannabis, as well likely why, may vary substantially depending upon variation legislation, promotion, acceptability around use. These factors create unique regionally specific 'cannabis contexts'. Although broader cross-cultural considerations apply all addictions we believe they are particularly important given global changes towards more lenient policies. aim increase awareness stimulate research debate regarding contexts shape processes underlying disorder (CUD) associated outcomes. percentage Δ9-tetrahydrocannabinol (THC) products has been increasing internationally [1], but there substantial markets type product Use higher-potency appears risen United States be common states legalized [2]. temporal regional health implications [3]. Further individual cannabinoid exposure, new THC rising popularity US market, with one six users reporting Δ8-THC [4]. produces fewer psychoactive effects than Δ9-THC, preferred those seeking medicinal benefit, indicating a potential difference attitudes Common routes administration (ROA) also differ throughout regions impact bioavailability cannabinoids. Cannabis combustion results faster onset action higher blood levels relative oral ingestion [5]. While smoking still most prevalent ROA Canada, edible [6] smoked flower combined tobacco European countries [7]. Nicotine cannabinoids compensatory synergistic neurobiological [8], nicotine–cannabis co-users severe CUD prognoses [9]. variations result differential frequent on other physical, cognitive mental policies, perceived it, influence trajectories probably contribute CUD. More permissive community heightened [10]. interplay policies feed into interact perceptions one's own producing different outcomes In States, availability declining parallel rates [11]. Despite such increases self-reported [12]. Some that, rather reflecting legitimate decline CUD, this seemingly contradictory pattern reflect reduced treatment-seeking some (e.g. [13]). tentatively agree: per se, concomitant drug then acquired, can alter drug's safety, turn potentially changing consequences [14].
