Abstract：
BACKGROUND: The increase in the use of psychoactive substances, alcohol and cigarettes in young people has become a public health problem. The identification of factors that increase or reduce the risk of exposure to these substances and the possible relationship between them is essential for planning strategies with a risk approach; hence the reason for this study. The objective was to establish the profile of use of psychoactive substances, alcohol and cigarettes and the factors associated with such use in nursing students of a higher education institution.
METHODS: Quantitative, observational, analytical cross-sectional study.
RESULTS: We included 310 students from 1 st to 9th semester of a Nursing programme from a private higher education institution in Bogotá. The prevalence of psychoactive substance use in the last year was 2.96% (95%CI, 1.36-5.54), with marijuana being the substance most used (55.55%). The prevalence of alcohol and cigarette use during the last 12 months was estimated at 86.64% (95%CI, 83.24-91.0) and 12.16% (95%CI, 8.43-15.88) respectively. A statistically significant association was found between the use of these substances: alcohol use was associated with cigarette use (OR = 3.22; P = 0.006) and smoking was associated with psychoactive substance use (OR = 15.4; P < 0.001).
CONCLUSIONS: Alcohol use increases the likelihood of smoking cigarettes, and this in turn increases the likelihood of psychoactive substance use, in this university population.

摘要：
背景：精神活性物质使用的增加，年轻人的烟酒已成为一个公共卫生问题。确定增加或减少暴露于这些物质的风险的因素以及它们之间可能的关系对于采用风险方法规划策略至关重要；因此是这项研究的原因。目的是建立精神活性物质的使用概况，在高等教育机构的护生中，酒精和香烟以及与这种使用相关的因素。
方法：定量，观察,分析性横断面研究。
结果：我们纳入了310名来自波哥大私立高等教育机构的护理课程第一至第九学期的学生。去年精神活性物质使用的患病率为2.96%(95CI,1.36-5.54),大麻是最常用的物质（55.55％）。在过去的12个月中，酒精和香烟使用的患病率分别估计为86.64％（95CI，83.24-91.0）和12.16％（95CI，8.43-15.88）。这些物质的使用具有统计学意义：饮酒与吸烟相关（OR=3.22；P=0.006），吸烟与精神活性物质的使用相关（OR=15.4；P<0.001）。
结论：饮酒会增加吸烟的可能性，这反过来又增加了使用精神活性物质的可能性，在这个大学人口中。
