本研究的目的是针对不同地区的学生，例如不同的省份，使用一个单一阶段的样本设计。在这个样本设计课程中随机抽取，分层是根据年级和学区进行的，并试图将所有在研究当天在场的学生纳入其中。然而，在进行研究之前，必须征得这些学生家长的同意，这些学生符合各自的健康和教育部门的要求。为了收集足够的资料，本研究将使用包括若干项的调查问卷;这些项目将寻找关于学校规则、吸烟和物质使用、心理健康、社会和人口特征的信息。为了确保收集到的信息是可靠和有效的，将覆盖非常广泛的学生群体，除非他们不需要，否则他们将被要求匿名。这些信息也将与类似调查的可用数据进行比较，以检查一致性，特别是在涉及估算的地方。然而，这项研究可能会面临一些限制，可能包括无法从管理人员那里收集有关学校吸烟政策的信息，因此学生提供的信息将会像看起来那样有限。

The research intends to base on students in different regions, such as different provinces, and use a sample design which is single-stage. In this sample design classes are randomly selected and the stratification is done according to grade and school district and tries to incorporate all students who are present on the day of the study. Before carrying out the research though, it will be important to get consent from the parents of such students which follow the requirements put forward by the respective heath and education departments. In order to collect adequate information, the study will use questionnaires comprising several items; these items will seek to find information regarding school rules, smoking and substance use, mental health, and social and demographic characteristics. To ensure that the information collected will be reliable and valid, a very wide population of students will be covered and the respondents will be accorded anonymity unless otherwise they do not need it. The information will also be compared to the available data from similar surveys to check for consistency especially where estimates are involved.The study may however face limitations which may include inability to collect information about school smoking policy from the administrators thus the information provided by the students will be essential as limited as they may seem.
