Psychedelic drugs, particularly taking small amounts of psychedelics in a cyclical pattern over days (so-called microdosing), have garnered growing scientific and public interest, but representative data on different dosage levels is scarce. To better understand this trend, we surveyed a nationwide sample of 11,299 adults in Germany. The survey assessed lifetime and past six-month psychedelic use by dosage as well as socio-demographic variables (sex, age, education, employment status, household equivalence income, partner arrangements, and place of residence). Results show that 5.0% of respondents self-reported lifetime psychedelic use, while 0.7% reported past six-month use. Medium to high dosing was more prevalent than microdosing. Moreover, high probabilities of using multiple forms of psychedelics were uncovered. We also observed variation in use across socio-demographic groups. For example, psychedelics use was less likely in females than males, and older than younger respondents. Past six-month microdosing was less likely in rural areas, and past six-month medium to high dosing was less prevalent in individuals with higher income or who live with a partner. This study shows limited support for widespread use in Germany and highlights diverse usage patterns across socio-demographics. These findings can inform policies, especially considering the overlap in usage of various substances.
迷幻药物，特别是在数天内以周期性模式服用少量迷幻药物（即所谓的微剂量服用），已引起越来越多的科学关注和公众兴趣，但关于不同剂量水平的代表性数据却很匮乏。为了更好地理解这一趋势，我们对德国全国范围内的11299名成年人进行了抽样调查。该调查评估了按剂量划分的终生及过去六个月内的迷幻药物使用情况，以及社会人口统计学变量（性别、年龄、教育程度、就业状况、家庭等效收入、伴侣安排和居住地点）。结果显示，5.0%的受访者自我报告有终生迷幻药物使用经历，而0.7%的受访者报告在过去六个月内使用过。中等至高剂量使用比微剂量使用更为普遍。此外，还发现了使用多种迷幻药物形式的高概率情况。我们还观察到不同社会人口群体在使用情况上的差异。例如，女性使用迷幻药物的可能性低于男性，年龄较大者低于年龄较小者。农村地区过去六个月内微剂量使用的可能性较小，而收入较高或有伴侣共同生活的个人过去六个月内中等至高剂量使用的情况则不太普遍。这项研究表明德国广泛使用迷幻药物的情况得到的支持有限，并突出了不同社会人口群体的多样化使用模式。这些发现可为政策提供参考，尤其是考虑到各种物质使用情况的重叠。
