Different psychoactive substances are widely used in today's society. So far limited data are available on the use of psychedelics in the general population. The main aim of this study is to estimate the numbers of users of substances with psychedelic properties (classical psychedelics, cannabis, ecstasy, and ketamine) in the Czech Republic.
Data from two samples enrolled in representative cross-sectional questionnaire surveys in the Czech adult population in 2016 (n = 2,785) and 2018 (n = 1,665) were analysed. Prevalence rates were extrapolated to estimate numbers of current, i.e., last-year, users of psychedelics, and their socio-demographic profiles were compared with non-users and users of cannabis.
An estimated 5-6% of the Czech adult population (350-430 thousand people) used classical psychedelics (LSD, psilocybin mushrooms, ayahuasca) in their lifetime, increasing up to 28-30% when cannabis is included (1.9-2.1 million users). Current use of classical psychedelics reached 0.7-1.9% (50-130 thousand people), and 9-11% (590-750 thousand users) when cannabis was included. Users of psychedelics were more often males, of younger age and single.
No significant socio-demographic differences were found between users of classical psychedelics and recreational cannabis users, however, differences were significant when compared to non-users and users of other illicit drugs. Findings should further serve to inform drug policy and social and healthcare systems in respect to the use of psychedelics.
当今社会广泛使用着不同的精神活性物质。目前，关于普通人群使用致幻剂的数据十分有限。本研究的主要目的是估计具有致幻特性的物质（经典致幻剂、大麻、摇头丸和氯胺酮）在捷克共和国的使用者人数。
分析了 2016 年（n=2785）和 2018 年（n=1665）在捷克成年人群中进行的具有代表性的横断面问卷调查的两个样本中的数据。将流行率外推以估计去年使用致幻剂的当前用户人数，并将其社会人口统计学特征与非使用者和大麻使用者进行比较。
估计有 5-6%的捷克成年人口（35 万至 43 万人）在一生中使用过经典致幻剂（LSD、迷幻蘑菇、死藤水），当包括大麻时，这一比例上升到 28-30%（190 万至 210 万使用者）。目前经典致幻剂的使用率达到 0.7-1.9%（5 万至 13 万人），当包括大麻时，使用率为 9-11%（59 万至 75 万人）。致幻剂使用者中男性居多，年龄较小且单身。
与娱乐性大麻使用者相比，经典致幻剂使用者在社会人口统计学方面没有显著差异，但与非使用者和其他非法药物使用者相比，差异显著。研究结果应进一步为致幻剂的使用提供信息，以完善毒品政策和社会及医疗保健系统。
