RATIONALE
Cannabis users often claim that cannabis has the potential to enhance their creativity. Research suggests that aspects of creative performance might be improved when intoxicated with cannabis; however, the evidence is not conclusive.
OBJECTIVE
The aim of this study was to investigate the acute effects of cannabis on creativity.
METHODS
We examined the effects of administering a low (5.5 mg delta-9-tetrahydrocannabinol [THC]) or high (22 mg THC) dose of vaporized cannabis vs. placebo on creativity tasks tapping into divergent (Alternate Uses Task) and convergent (Remote Associates Task) thinking, in a population of regular cannabis users. The study used a randomized, double-blind, between-groups design.
RESULTS
Participants in the high-dose group (n = 18) displayed significantly worse performance on the divergent thinking task, compared to individuals in both the low-dose (n = 18) and placebo (n = 18) groups.
CONCLUSIONS
The findings suggest that cannabis with low potency does not have any impact on creativity, while highly potent cannabis actually impairs divergent thinking.
理论依据
大麻使用者常称大麻有提升创造力的潜力。研究表明，吸食大麻时创造性表现的某些方面可能会得到改善；然而，证据并不确凿。
目的
本研究旨在探究大麻对创造力的急性影响。
方法
我们在一群经常使用大麻的人群中，研究了吸入低剂量（5.5毫克Δ⁹-四氢大麻酚[THC]）或高剂量（22毫克THC）大麻与安慰剂相比，对涉及发散性（替代用途任务）和聚合性（远距离联想任务）思维的创造力任务的影响。该研究采用随机、双盲、组间设计。
结果
与低剂量组（n = 18）和安慰剂组（n = 18）的个体相比，高剂量组（n = 18）的参与者在发散性思维任务上的表现明显更差。
结论
研究结果表明，低效力大麻对创造力没有任何影响，而高效力大麻实际上会损害发散性思维。
