Psychotomimetic Effects

Background: While the acute effects of cannabis are relatively benign for most users, some individuals experience significant adverse effects. This study aimed to identify whether variation in schizotypal personality traits and frequency of cannabis use influence the acute effects of delta-9-tetrahydrocannabinol (THC). Methods: Individual participant data from four double-blind, randomised, placebo-controlled, acute crossover studies involving 128 cannabis users were combined for a mega-analysis. Using multilevel linear models and moderation analyses, frequency of cannabis use and schizotypal personality traits were investigated as potential moderators of the subjective, cognitive and psychotomimetic effects of acute THC. Results: There was evidence of a moderating effect where increased frequency of cannabis use was associated with reduced intensity of subjective (changes in alertness and feeling stoned) and psychosis-like effects following THC when compared with placebo. Moderating effects of cannabis use frequency on acute memory impairment were weak. Trait schizotypy did not moderate the acute psychosis-like effects of THC compared with placebo. Conclusions: Our results suggest that a pattern of domain-specific tolerance develops to the acute effects of THC. Tolerance to the alertness-reducing effects occurred more readily than tolerance to psychotomimetic effects. Only partial tolerance to feeling stoned was found, and there was weak evidence for tolerance to memory impairment. Trait schizotypy did not moderate THC’s effects on psychotomimetic symptoms.

The Impact

High levels of linguistic referential failures are associated with liability to develop schizophrenia-spectrum disorders, and it has been shown that these failures can differentiate healthy subjects, high-schizotypal and schizophrenics groups. Nevertheless, few investigations have focused on whether or not schizotypal traits in nonclinical populations can also impact linguistic reference. In Brazilian Portuguese, only one previous study (acceptability judgements task) had been conducted, and its results suggest association between schizotypal traits and a more rigid preference for assignment of specific readings to definite singular DPs. Here, we present another experimental study in Brazilian Portuguese,  a comprehension task designed to examine possible effects of schizotypal personality traits on the interpretation of definite singular DPs. The findings, in line with the previous results, support the conclusion that schizotypy does affect the interpretation of definite singular DPs in Brazilian Portuguese. Together, these two experiments suggest that schizotypal personality traits impact the integration of linguistic contextual information into the semantic meaning of definite DPs. This is  consistent with the general hypothesis that schizotypy, similarly to schizophrenia, is associated with pragmatic difficulties. Yet, our results emphasize that the impact of schizotypal traits on pragmatics can be observed even in healthy (nonclinical) speakers.
