Sources
- Barrus and colleagues (2016), an occasional paper of RTI Press, is a review written for policy makers. It is the source for how edibles are made, the oral pharmacology, the Colorado sales figures, the state rules of 2016 and the label studies, several of which it reports from other works (the Colorado Department of Revenue, The Denver Post, Vandrey and colleagues in JAMA 2015, the 2014 death described by Hancock-Allen and colleagues). Those findings are given as the review reports them. Its figures for the onset and peak of oral THC come from Grotenhermen (2003), and its 6 to 10 per cent oral bioavailability from Schwilke and colleagues (2009).
- The state rules described are those the review reports as in force in 2016.
- The Canadian limits are from the consolidated Cannabis Regulations (SOR/2018-144) as current to 19 October 2026; the reasons for them are from the Regulatory Impact Analysis Statement published with the 2019 amendments in the Canada Gazette.
- The Australia and New Zealand hemp-seed figures are from the Stage 2 survey report of July 2022, prepared for the Implementation Subcommittee for Food Regulation with the NSW Food Authority as lead agency and published by Food Standards Australia New Zealand.
Two measures of Colorado's edible sales
- The RTI review puts the 4.81 million edible units sold in Colorado in 2014 at about 45 per cent of the state's cannabis sales, citing the Department of Revenue. Monte and colleagues (2019) give edibles 0.32 per cent of the cannabis sold from 2014 to 2016 by weight of THC, assuming 10 mg of THC per edible unit and 20 per cent THC in flower. The two figures count different things (units against kilograms of THC) and are not in conflict.
Onset times
- The RTI review gives 30 to 90 minutes for the first effects of eaten THC and two to four hours for the peak. In the 2020 brownie trial of Schlienz and colleagues effects appeared after 30 to 60 minutes and peaked at 1.5 to 3 hours. Both are given in the article, each with its source.
