Based on a procedure reported by Crombie and coworkers, a solution of olivetol and food-grade α-phellandrene in benzene was treated with p-toluenesulfonic acid monohydrate and the mixture was allowed to stir at room temperature for 1 h. Te solvent was removed in vacuo and the residue was purified by silica gel chromatography using a gradient elution to give H2CBD as a […]

These data clearly suggest that terpenes are degraded with temperature in the vaping proces
The same logic applies to the generation of 4- methylpentanal from VEA, which dominates the distribution of the isomer pair over hexanal. The formation of glyoxal likewise may be enhanced in VEA due to the higher stability of radical intermediates. Diacetyl is thought to be a byproduct of cannabis plants.However, the SIC of C4H6O2 in the […]
Internal factors are also important drivers of bike sharing ridership
Shared micromobility services are growing rapidly across the United States and abroad. In 2018, the number of shared micromobility trips in the U.S., including station-based and dockless bike sharing and e-bike sharing and scooter sharing, reached 84 million . Of those trips, 36 million were station-based bike sharing trips, about 500,000 were station based e-bike sharing trips, and about 6 million were dockless […]
Marijuana and tobacco frequency were assessed at all 13 time points
A second goal was to test whether post-legalization changes in marijuana trajectories would be moderated by demographic or other substance use factors. We expected to see greater increases in use among male participants, and among those who used other substances more frequently. Finally, we explored whether changes in marijuana use frequency following legalization were related […]
The dashed lines represent linear fits where subjects marked in blue were excluded from the calculation
The amplitudes of BOLD and CBF percent signal changes, both during rest and task, were calculated as root mean square values by computing the standard deviation across the length of the time courses. Note that for the task-related BOLD and CBF signals, only the last 3 cycles were used in this calculation. As CBF signal […]
Two additional measures of connectivity within hemispheres were calculated as well
Obrig et al. used near infrared spectroscopy to show that hypercapnia also attenuates spontaneous fluctuations in cerebral oxygenation in awake humans. In general, the prior studies suggest that vasodilation reduces the amplitude of spontaneous fluctuations, while vasoconstriction tends to increase fluctuations.Similar to task-related studies, the results of these resting-state studies suggest that the strength of […]
Anderson et al. were the first to estimate the effects of medical marijuana enactment on traffic fatalities
Table E.1 compares estimates of the effects of growth in the legal market on past month use restricting the sample to only include Montana and its bordering states in Panel A, to the estimates using the entire sample of states in Panel B. If there are substantial supply spillovers from MML states with large markets […]
The most widely used data on marijuana prices comes from two data sources
By reducing the perceived risk of federal prosecution for legal producers in compliance with state law, the Ogden Memo should have increased benefits to patients by increasing medical marijuana availability. The Cole Memo should have had the opposite effect. If supply-side factors are an important determinant of the relative value of medical marijuana participation, To […]
Relevant methods have been discussed in diverse prior work
Tobacco policies at the state, county, and city jurisdiction levels had similar degrees and patterns of co-occurrence among policies. For example, comprehensive clean-air laws for bars and comprehensive clean-air laws for restaurants frequently co-occurred at the state, county, and city levels . Most policy measures were positively correlated, but we also found pockets of negative […]
The CMU is designed as a multiplying delay locked loop producing a 6GHz clock
The repeater last stage exhibits large gain at the transition period that amplifies the stage internal noise sources as well as preceding stages noise. When transition completes, the gain drops and output noise also drops drastically. Thus the average noise is low compared to transition noise. Jitter at the output of the repeater is thus […]
