i know the evidence re THC suppressing REM sleep (where dreaming happens) is …

💤 While cannabis use and sleep disturbance are commonly discussed in clinical encounters, the evidence regarding THC’s specific effects on REM sleep remains inconsistent across studies, with variation attributable to differences in dosing, frequency of use, duration of observation, and individual metabolic factors. Patients often report subjective sleep improvement with cannabis in the short term, though this may reflect sedation rather than restoration of normal sleep architecture, and tolerance to sleep benefits typically develops within weeks. The clinical significance of REM sleep suppression, if it occurs reliably, remains unclear—some data suggest potential cognitive or emotional processing consequences, while other work questions whether this translates to clinically meaningful harm in regular users. Given the complexity and gaps in evidence, providers should assess individual sleep patterns and daytime functioning rather than assuming cannabis use uniformly impairs or improves sleep quality. Counseling should acknowledge both the perceived benefit patients may experience and the uncertainty about long-term sleep architecture
