I did once and had an awesome time. Def the highest I've ever been. Like smoking the intensity depends on how much you consume. One problem is that it takes a while to hit you so you don't know how high your going to get until its too late. In my case I ate one cookie then after 1/2 hr or so didn't feel anything and ate another. I should have stuck with the one cookie The other problem, or advantage depending on your point of view, is that it lasts a long, long time. So, if you have eaten a bunch you better just settle in for a bit cus it's not going to wear off anytime soon.
