Medical Cannabis for IBS — Switzerland 2026

The endocannabinoid system regulates gut motility and visceral perception. Cannabis can ease IBS symptoms — much cheaper for members.

TL;DR: IBS affects ~10 % of the Swiss population. The gut is rich in CB1/CB2 receptors; cannabinoids modulate motility and visceral hypersensitivity. Wong 2011 (RCT): dronabinol reduced colonic motility in IBS-D. CBD-rich oils empirically effective for pain and anxiety. CannabisClub members: 50 CHF flat instead of 190.
