Instead of using the internet for information and misinterpreting it I suggest you try something yourself before acting like you're all smart and experienced. It doesn't need to be heat-activated in order for you to feel the effects. If you ate 2 pounds of weed (any kind) basically, you would be fucked out of your mind for days. If you think you're so right, I dare you to eat a gram of Hash raw, hell I dare you to eat a g of Schwag, you would still get so fucked up.
Anyway to those who do want to try it, don't ever eat that much. A Small nug of Hash is enough for you to be high for a long ass time, longer than you would be when smoking it. Basically take the same amount you would smoke and put it in your mouth, make sure you clean it out if you have Schwag or something, get rid of seeds and stems as you would when smoking it (they can make you pretty sick), and chug it down with some water. Oh yeah and make sure you are on an empty stomach when you do it. I don't do it often because I just like smoking it, but if you are one of those who don't want to smoke anymore, it's a good alternative. It takes an hour or so, sometimes more for the effects to kick in, but once they do you will be pretty baked, guaranteed. If you eat too much you might be nauseous so be carefu, when I ate my first time I ate way too much and when I woke up in the morning I was throwing up. Why did I eat so much? Because I thought you would need more than you do when you smoke. But as it turns out that's not the case at all, and it takes roughly the same amount for a more powerful effect.
