What can we learn from low-THC cannabis growers in Europe? A comparative transnational study of small-scale cannabis growers from Italy and Switzerland

Abstract

BackgroundA market for cannabis with low levels (LT) of Tetrahydrocannabinol (THC) has recently emerged in Europe alongside an ongoing trend of domestic cannabis cultivation with high-THC content (HT). This phenomenon may have diversified the growers’ profile. This study investigates LT growers’ (LTG) characteristics (demographics, consumption patterns, growing experience) and growing motivations with a subsequent comparison with HT growers (HTG). MethodsData from 11,479 small-scale growers was collected through an online survey (ICCQ 2) conducted by the Global Cannabis Cultivation Research Consortium (GCCRC) from 2020 to 2021. This exploratory study analyses a subsample of the 1618 respondents residing in Italy and Switzerland. A quantitative approach was used, performing comparative bivariate and multivariate analyses between participants who have only grown HT plants in the previous year (HTG; n = 1303) and those who have either grown LT only or alongside HT (LTG; n = 315). ResultsLTGs differ significantly from HTGs. LTGs are older than HTGs. Growing medical cannabis for oneself and others is more likely among them than HTGs. Compared to HTGs, LTGs have lesser odds to grow for recreational use and to have problematic cannabis use. Growing for legality, pleasure and accessing milder cannabis is more likely for LTGs than HTGs. HTGs have greater experience than HTGs, growing for longer, more extensively and better meeting their consumption needs. There is a wider production of by-products, such as oils and extracts, among LTGs than HTGs. Having been in contact with the police for growing is also more likely among them than HTGs. ConclusionLTGs reported significantly more growing experience when compared to HTGs and should be considered a distinct group of growers. The results suggest that the emergence of the legal LT market has more likely drawn previous HTGs into growing LT, mainly medically, rather than attracting new individuals toward cannabis cultivation.
