PCP or angel dust, peyote, mescaline, DMT, AMT, or Foxy”). The ABCD study assesses tryptamine hallucinogens, including lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT), and ayahuasca (Callaway et al., 1999; McKenna et al., 1984; McKenna and Riba, 2015), synthetically produced tryptamine hallucinogens, such as alpha-methyltryptamine (AMT), or 5-methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT), which have similar effects (Araújo et al., 2015; Meatherall and Sharma, 2003), phencyclidine (PCP), mescaline, and peyote (Halpern et al., 2005; Carstairs and Cantrell, 2010). Unit of measurement is in occasions; visual aids are provided to note what types of hallucinogens they have used.12.Hallucinogen psilocybin (“described as magic mushrooms or shrooms”). Use of psilocybin appears more common than other hallucinogens (Hardaway et al., 2016; Hendricks et al., 2014; Hallock et al., 2013); psilocybin is also important to track because of the increased attention to use of psilocybin as a form of addiction treatment (Bogenschutz, 2017). The unit of measurement is occasions (max in grams); visual aids are provided to assist with dosing and identification of the drug.13.Hallucinogen salvia divinorum (“salvia”) is measured in occasions; visual aids are provided to assist in identifying salvia and measuring max use (in mg).14.Anabolic steroids (“arnolds, pumpers or roids”) is measured in occasions; visual aids assist in
