From the Guidelines

THC-induced hyperesthesia is a real medical condition, not a disease per se, where excessive cannabis use leads to heightened sensitivity to pain. This paradoxical effect occurs when THC, the main psychoactive component in cannabis, overstimulates the endocannabinoid system, particularly in chronic, heavy users. The condition typically manifests as increased sensitivity to touch, temperature, or pain, especially in the abdominal area.

Key Points

  • Treatment involves complete cessation of cannabis use, which usually resolves symptoms within days to weeks.
  • Supportive care may include hydration, anti-nausea medications like ondansetron 4-8mg every 8 hours as needed, and sometimes short-term pain management with non-opioid analgesics such as acetaminophen 500-1000mg every 6 hours or ibuprofen 400-600mg every 6-8 hours.
  • Hot showers temporarily relieve symptoms for many patients, though this is not a long-term solution.
  • This condition is part of Cannabis Hyperemesis Syndrome (CHS), which also includes cyclical vomiting and abdominal pain, as discussed in a recent commentary on the diagnosis and management of CHS 1.
  • The hyperesthesia component occurs because chronic THC exposure leads to desensitization of cannabinoid receptors and disruption of normal pain processing pathways in the central nervous system.

Considerations

  • Cannabis use has been associated with various health effects, including mental health and chronic respiratory problems, as well as potential risks for adverse cardiovascular events and allergic reactions 2, 3.
  • The increasing THC concentration in cannabis plants and products may elevate the risk for health problems, highlighting the need for caution and further research on the effects of cannabis use.

From the Research

THC Induced Hyperesthesia

  • There is no direct evidence in the provided studies to support the existence of THC-induced hyperesthesia as a real disease.
  • However, the studies do mention various adverse effects of THC, including: + Adverse effects from higher doses, such as fear, distrust, and a profound state of unease, hallucinations, ataxia, stupor, and seizures 4 + Cannabis hyperemesis syndrome, a form of functional gut-brain axis disorder characterized by bouts of episodic nausea and vomiting worsened by cannabis intake 5 + Dose-dependent adverse events, such as deterioration of primary study outcomes, e.g., in psychosis 6 + Non-serious adverse events, usually dose-proportional, subject to tachyphylaxis, and rarely dose-limiting when patients are commenced on a low dose with gradual up-titration 7 + Potential adverse drug events related to THC when combined with other medications, including metabolic drug-drug interactions and pharmacodynamic interactions 8
  • It is possible that THC-induced hyperesthesia may be related to or be a symptom of one of the mentioned adverse effects, but further research is needed to confirm this.
