Abstract
BackgroundThe study aimed to assess the prevalence and correlates of non-daily and daily cannabis use among persons 15 years and older in South Africa.MethodIn a national cross-sectional 2017 survey, 39,207 persons 15 years and older (Median = 34 years) responded to a questionnaire on cannabis use and health variables. Multinominal logistic regression was used to assess the determinants of nondaily and daily cannabis use among the general population and logistic regression for the determinants of daily cannabis use among active cannabis users.ResultsResults indicate that 5.0% of the participants engaged in non-daily and 2.8% in daily cannabis use in the past 3 months. In adjusted multinomial logistic regression analysis, male sex, Grade 8–11 education, Coloureds, alcohol use disorder, never married, and other drug use were positively associated with daily cannabis use while not in not labour force was negatively associated with daily cannabis use. Moreover, male sex, never married, alcohol use disorder, and other drug use were positively, while physical multimorbidity was negatively associated with nondaily cannabis use. In adjusted logistic regression, compared to nondaily cannabis users, daily cannabis users were more likely male and were less likely not in the labour force and were less likely using other drugs.ConclusionAbout one in ten participants had used cannabis in the past 3 months in South Africa. Several sociodemographic and health indicators were identified that were associated with non-daily and/or daily cannabis use.
Highlights
Cannabis is the genus name of a plant from the Cannabaceae family [1] and cannabis is the name associated with the drug produced from this plant [2]
More recent South African data on cannabis use can be found from treatment centre data that shows that cannabis is the most used drug in South African treatment facility cases in the second half of 2016 [9] and the first half of 2017 [10]
Associations with non-daily and daily cannabis use among the general population In adjusted multinomial logistic regression analysis, male sex, Grade 8–11 education, Coloureds, alcohol use disorder, never married, and other drug use were positively associated with daily cannabis use while not in not labour force was negatively associated with daily cannabis use
Summary
Cannabis is the genus name of a plant from the Cannabaceae family [1] and cannabis is the name associated with the drug produced from this plant [2]. In terms of cannabis usage in different countries around the world, the prevalence of past 12-month cannabis use in Australia was 6% in 2012 [7] and the annual. In terms of UNODC cannabis statistics for South Africa, the organisation reports an annual cannabis prevalence at 3.65% in 2011, and that 43.3% of people in treatment facilities in 2018 were admitted for cannabis use [6]. In terms of a national population-based South African study, a 2012 study on persons 15 years and older reported the prevalence of past 3-month cannabis use at 4.0% [8]. There is a lack of more recent national population-based data on the prevalence and correlates of nondaily and daily cannabis use in South Africa. The study aimed to assess the prevalence and correlates of non-daily and daily cannabis use among persons 15 years and older in South Africa
