He must not have known much about weed if he thought he was going to die. I can understant it, coming from an ignorant viewpoint. Last year me and my friends, with our high tolerances, made some hash brownies that were WAAAAAAYYYYY too potent. My friends thew up and went to sleep, but I wasn't so fortunate as I can never puke. It kicked in so hard I thought I was on a hard salvia trip, and I spent the whole night lying awake and drinking water every 30 seconds from the worst dehydration I've ever experienced. I stayed awake till the sun came up, barely holding my mind together, and was stoned all day long after that. I couldn't even touch weed for a month after that, I can easily see how someone would think they're going to die. But I didn't die, or even harm myself, because that's impossible
