Cannabis concentrates, which are cannabis plant extracts that contain high concentrations of Δ-9-tetrahydrocannbinol (THC), have become increasingly popular among adults in the United States. However, no studies have reported on the prevalence or correlates of cannabis concentrate use in adolescents, who, as a group, are thought to be particularly vulnerable to the harms of THC.
Participants are a racially and ethnically diverse group of 47 142 8th-, 10th-, and 12th-grade students recruited from 245 schools across Arizona in 2018. Participants reported on their lifetime and past-month marijuana and cannabis concentrate use, other substance use, and risk and protective factors for substance use problems spanning multiple life domains (ie, individual, peer, family, school, and community).
Thirty-three percent of all 8th-, 10th-, and 12th-graders reported lifetime cannabis use, and 24% reported lifetime concentrate use. Seventy-two percent of all lifetime cannabis users had used concentrates. Relative to adolescent cannabis users who had not used concentrates, adolescent concentrate users were more likely to use other substances and to experience more risk factors, and fewer protective factors, for substance use problems across numerous life domains.
Most adolescent cannabis users have used concentrates. Based on their risk and protective factor profile, adolescent concentrate users are at higher risk for substance use problems than adolescent cannabis users who do not use concentrates. Findings raise concerns about high-risk adolescents' exposure to high-THC cannabis.
大麻浓缩物是大麻植物提取物，含有高浓度的 Δ-9-四氢大麻酚（THC），在美国成年人中越来越受欢迎。然而，目前尚无研究报告青少年使用大麻浓缩物的流行率或相关因素，一般认为青少年特别容易受到 THC 的伤害。
参与者是一个种族和民族多样化的群体，由 2018 年从亚利桑那州 245 所学校招募的 47142 名 8 、 10 和 12 年级学生组成。参与者报告了他们一生中及过去一个月的大麻和大麻浓缩物使用情况，以及其他物质使用情况，以及跨越多个生活领域（即个人、同伴、家庭、学校和社区）的物质使用问题的风险和保护因素。
所有 8 、 10 和 12 年级学生中，有 33%报告有过一生中使用大麻，有 24%报告有过一生中使用浓缩物。所有一生使用大麻的人中，有 72%的人使用过浓缩物。与未使用浓缩物的青少年大麻使用者相比，青少年浓缩物使用者更有可能使用其他物质，并且在多个生活领域中经历更多的物质使用问题风险因素，而保护因素较少。
大多数青少年大麻使用者都使用过浓缩物。根据他们的风险和保护因素特征，与不使用浓缩物的青少年大麻使用者相比，青少年浓缩物使用者更容易出现物质使用问题。这些发现引发了对高风险青少年接触高 THC 大麻的担忧。
