I think he's talking about the edible that is made from a pot extraction (coconut oil is often used) put into pills. You can keep them in the fridge/freezer and they'll be fine for a quite a while. Google Cannabis capsule and you'll find many recipes. I prefer other edibles, but the capsules are extremely convenient, I can't make them though because I'm a vegetarian and vegetarian capsules don't work for them from what I hear. You can accomplish the same thing as the capsules (and have the process be easier) if you do all the steps except instead of putting the weed oil into pills you put it into a jar or whatever and put it in the fridge, then just eat some on toast or even straight when you want to. Either way, pot oil lasts for a pretty good amount of time if refrigerated and you can certainly make more then a days supply of oil/capsules without having it go bad.
