“…The most common form of MC consumption was inhalation (reported in 35 studies), either via smoking (joint or blunt, joint with tobacco, pipe, water pipe) or vaping (vaporizer) [34, 36, 51, 58-63, 65, 68-70, 72, 74-86, 88, 92, 94-97, 99, 101]. Reported smoking prevalence ranged from 20% [85] to 91% [59] and vaping prevalence from 7% [60] to 53% [78]. Ingested (cannabis tea, baked goods, oils, tinctures, tablets and capsules) [51, 58-61, 63, 65, 67-70, 72, 75, 76, 80-83, 85, 86, 88, 95, 97, 99] and topical administration [58,59,63,75,80,99] were less common forms of MC use (reported in 25 and 6 studies, respectively).…”
