Correlations between cannabis consumption, problems with cannabis use, and self-reported problems with prospective memory.

Note: bold indicates p≤.01. PMQ = Prospective Memory Questionnaire; PRMQ = Prospective and Retrospective Memory Questionnaire; TCPMQ = Time−Cued Prospective Memory Questionnaire. Higher scores on the prospective memory questionnaires indicate more frequent prospective memory failures or greater use of memory aiding strategies. Higher scores on the punctuality subscale of the TCPMQ indicate performance of tasks later. Higher scores on the cannabis consumption and problems with use variables indicate greater cannabis consumption and more problems associated with cannabis use, respectively.
