The second factor, “Persistence,” is comprised of Omax, Pmax, breakpoint, and elasticity, and reflects the individual’s sensitivity to increasing cost . This factor structure aligns with research demonstrating a similar structure for alcohol and tobacco purchase tasks . Responses on hypothetical purchase tasks have been shown to be an accurate reflection of demand for the…
These non-emotional control processes are also implicated in cannabis use
In turn, while some teams have observed otherwise , cannabis use, particularly in hazardous ways, may negatively influence the neurodevelopmental trajectory, placing youth at greater risk for sustained patterns of cannabis use and related health consequences as they transition into adulthood.Understanding this multifi nality will require designs accounting for within-person and contextual differences among youth.…
Such cognitive differentiation is also critical to understanding the developmental neuroscience underlying cannabis use and abuse
Understanding this multifinality will require designs accounting for within-person and contextual differences among youth. Recent youth cannabis studies, including the 2017 National Academies of Science cannabis report, also reflect negative neurocognitive and health sequelae associated with cannabis use during this developmental window.The risk for negative health sequalae is higher when use is initiated in adolescence…
It can also be extended to safety–critical fields other than driving, such as piloting aircrafts or operating heavy machinery
Situational awareness , is important for recognizing scenario elements that, while not an immediate threat, may pose a hazard in the short term such as animals or turning vehicles in the periphery. As a working example we have developed a simulated driving scenario that reflects the considerations and resulting features discussed above for use in…
Future research should continue to examine the rates of home cultivation by province and retail structure over the years
Analyses were conducted using survey procedures in SAS . In 2020, Nova Scotia reported the highest percentage of respondents that grew cannabis plants , whereas Manitoba reported the lowest . Provinces with public retail structure, i.e., a government-run retail structure, reported the highest and lowest percentages of home cultivation, whereas provinces with private and hybrid…
Except for total dry cannabis used, differences between the CEA and TLFB were non-significant
A self-report measure that can be completed more quickly may be more desirable when a participant is completing a host of other measures as well. In sum, measurement of cannabis use has generally not kept pace with shifts in patterns and modes of engagement and measures that do capture the diversity of ways in which…
The phylum Proteo bacteria were decreased in cannabis smokers compared with those of non-smoking controls
The effects of cannabis on human health have been extensively studied, and public acceptance of cannabis for medicinal and recreational use grows worldwide.However, numerous studies in both humans and animals have demonstrated that cannabis use impairs neural functioning in a variety of cognitive and performance tasks, such as memory, learning, attention, perception, and motor coordination…
Tobacco and cannabis use among adolescents and young adults is a public health concern
Estimates from Wave 4 are nationally representative of the US civilian, noninstitutionalized population. Additional information on the PATH Study sampling design, participant documentation, and data access can be found elsewhere . Respondents with missing data on nicotine and cannabis vaping indicators and covariates were excluded, resulting in a final analytic sample of 3795. This research…
The movement of predator larvae were not significantly impeded by the surface of C. sativa leaves
Specifically, the behavior, including mobility of the larvae of C. carnea was unaffected by leaf surface . In addition, the larvae of A. aphidimyza spent significantly more time crawling on C. sativa leaves compared to sweet-pepper leaves. This might be explained by the different strategies and morphologies of the larvae of the two predators and…
Early studies examined effects of applying THC to brain slices
Activation of TRPV1 receptors by AEA appears to be the mechanism underlying this synaptic depression. The catabolic enzyme for 2-AG is monoacylglycerol lipase . Inhibition of MAGL by the JZL184 compound inhibits repetitive stimulus-driven dopamine release, as previously described for FAAH inhibition . Inhibitors of MAGL have little effect on synaptic transmission when applied alone,…
