This study examined the effects of delta 9-tetrahydrocannibinol (THC) on defensive, primary-process, and secondary-process language. Four male volunteers provided 5-minute monologues in three conditions: Round 1,placebo; Round 2, 15 mg THC; Round 3, recovery. THC was found to attenuate defensive language behavior (retractors, qualifiers, direct references) and to increase the use of secondary-process (intellectualizing) vocabulary.
本研究考察了δ9-四氢大麻酚（THC）对防御性语言、初级过程语言和次级过程语言的影响。四名男性志愿者在三种条件下进行了5分钟的独白：第一轮，服用安慰剂；第二轮，服用15毫克THC；第三轮，恢复阶段。研究发现，THC可减弱防御性语言行为（退缩词、限定词、直接指代），并增加次级过程（理智化）词汇的使用。
