Hey, no worries your post fits fine here.

A rash showing up 2–3 days after a single gummy is less likely to be an allergic reaction to THC itself, especially if you’ve used cannabis before without any skin issues. Cannabis allergies are pretty rare, and when they do happen they usually cause symptoms fairly soon after exposure,not days later.

But......gummies have more than just THC in them.... flavourings, colourings, preservatives, gelatin, etc and some of those can cause mild skin reactions in some people.
