People can eat an edible and feel fine for a while but as the edible works its way through your system things can become not so fine. I ate an  edible  once and a couple hours later, while driving home, I experienced what I would call a panic attack and I barely made it home. Later on I ended up on my kitchen floor because my heart pounded so hard and  that night I ended up in the hospital.  The whole experience from a tiny edible (gum drop size) lasted about 6 hours.  Edibles are incredibly powerful. I think I am lucky to be alive.
