The results of a survey based on a sample of 4,059 students attending intermediate and upper intermediate schools in Mexico City and its metropolitan area showed that the percentage of drug use "ever" by substance was the following: alcohol, 59; tobacco, 53.2; inhalants, 5.4; cannabis, 3.8; tranquilizers, 3.1; amphetamines, 2.7; sedatives, 1.3; opium, 0.91; LSD, 0.54; cocaine, 0.52; heroin, 0.29. Of the students reporting use "ever", the percentage reporting use of one of these substances "in the past months" ranged from 22.5 to 58.3. While there were more female students among the users of tranquilizers and stimulants, male students predominated among the users of other substances, with the difference being most pronounced among cannabis users. Older students were more involved with cannabis; in contrast, inhalants were more popular with younger students. The use of other substances varied little with age. Use of alcohol and cannabis was also most frequent among students of schools in middle, upper middle and upper class areas, whereas use of inhalants was most common among students attending schools in lower class areas.
一项针对墨西哥城及其大都市区4059名初中和高中学生样本的调查结果显示,按物质划分的“曾经”使用毒品的百分比情况如下:酒精,59%;烟草,53.2%;吸入剂,5.4%;大麻,3.8%;镇静剂,3.1%;安非他明,2.7%;镇静药,1.3%;鸦片,0.91%;麦角酸二乙胺,0.54%;可卡因,0.52%;海洛因,0.29%。在报告“曾经”使用过毒品的学生中,报告在“过去几个月”使用过这些物质之一的百分比在22.5%至58.3%之间。虽然在使用镇静剂和兴奋剂的人群中女生较多,但在使用其他物质的人群中男生占主导,这种差异在大麻使用者中最为明显。年龄较大的学生更多地使用大麻;相比之下,吸入剂在年龄较小的学生中更受欢迎。其他物质的使用随年龄变化不大。酒精和大麻的使用在中、中上等和上等阶层地区学校的学生中也最为频繁,而吸入剂的使用在下层阶级地区学校的学生中最为普遍。
