青少年吸毒行为是当今我国面临的不容忽视的社会问题。中学阶段是吸毒行为发生的关键时期，针对中学阶段青少年的吸毒行为及个体影响因素开展研究，对有效预防和干预青少年吸毒行为有重要意义。本研究使用问卷法，以工读学校和普通中学两类学校的680名青少年为被试，对其吸毒行为的特点和现状进行调查，并探讨青少年吸毒行为的个体影响因素的作用。研究结果表明：1、中学阶段青少年吸毒行为有一定程度的发生率。在调查的被试中有12.3%的青少年有吸毒行为。工读学校吸毒比例高于普通中学吸毒比例。2、中学阶段青少年吸毒更多使用新型毒品。并且混合使用新型毒品的情况居多。在调查被试中，混合使用两种及两种以上新型毒品人数占吸毒人数的72%。3、中学阶段是青少年吸毒行为发生的起始阶段。被试中首次吸毒行为发生的最早年龄是10-11岁之间，大多数吸毒被试在12-16岁之间开始发生吸毒行为。4、青少年吸毒行为的发生与抽烟、喝酒及其他问题行为存在共生性，但是抽烟频率、问题行为水平与吸毒的程度并无关联，喝酒频率与吸毒程度有一定的相关性（r= .242，p<.05）。5、抵制效能、吸毒态度、拒绝意图、感觉寻求、自我控制各因素与吸毒行为存在不同程度的显著相关关系，抵制效能和吸毒态度的相关较高。但各因素影响作用不同。其中，抵制效能、吸毒态度对工读学校被试是否吸毒的影响更重要，而感觉寻求对普通中学被试是否吸毒的影响更重要。 6、个体行为倾向性因素中，抵制效能、吸毒态度、拒绝意图对是否吸毒的关系存在相互影响，抵制效能是是否吸毒的最重要的影响因素。7、个人特质变量中，感觉寻求是对是否吸毒有重要影响的因素，自我控制的影响作用较小。8、学校性质、感觉寻求、抵制效能、是否抽烟共同可以预测是否吸毒的75.3%。
