Chronic pain patients who use cannabis more frequently show weaker emotion regulation abilities

Smaller reductions in skin conductance and corrugator muscle activity during emotion regulation tasks were associated with more days of cannabis use over 90 days. Pain severity was not significantly associated with cannabis use frequency.

Researchers analyzed data from 104 participants (mean age 51, 68% female, 89% White) receiving long-term opioid therapy for chronic pain. Cannabis use was measured as days used over 90 days. Emotion regulation was assessed via psychophysiological measures during passive viewing vs. cognitive reappraisal of negative images.

Many chronic pain patients report using cannabis to manage pain, but this study suggests the primary driver may actually be emotional distress rather than physical pain. If true, this shifts the conversation about why pain patients use cannabis and what interventions might help.

The disconnect between pain severity and cannabis use frequency challenges the common assumption that pain patients use cannabis primarily for analgesia. If emotion regulation deficits are the stronger predictor, targeted psychological interventions like mindfulness-based approaches might reduce problematic cannabis use more effectively than simply addressing pain.

Cross-sectional design means causality cannot be determined: it is unclear whether poor emotion regulation leads to more cannabis use or vice versa. The sample was 89% White and predominantly female, limiting generalizability. Self-reported cannabis use days may be imprecise.
