Eating weed is different from smoking it, a more mellow, body high. I remember in the 1970s I was going to bake a pizza in my parent's oven for myself and decided to crumble about a quarter ounce of pot on it as a topping just to see what it was like. That is enough to get you high for days. It was an expensive choice but it seemed the required amount.
Unexpectedly, it smelled GREAT as it baked into the cheese and toppings like an herb, and it filled the entire house with this wonderful piquant aroma. When it was baked to perfection, I took it out and my father had smelled it and came looking for a piece! He wanted to eat some of it! I could not risk a stoned father, I have no idea what effect it might have had, so I had to refuse him and tell him next time--- I felt terrible, he probably thought I was just being selfish, greedy and stingy, but I could not take the chance of getting him high.
So I ate the whole pie. About 20 minutes later I began to feel it, and I kept feeling it and feeling it, it kept getting stronger until my entire body was stoned! And I was ripped for many hours! I shudder to think what my father might have thought or done had he known there was pot in that pie much less if I had drugged him. Who knows, he might have been real mellow or enjoyed it but I kinda doubt it.
