This was a lesson that my brother's friend learned on NYE. My brother had asked if he could invite a friend to our party. This guy showed up and was pounding beers. A friend of mine brought pot cookies with him. I personally am not a fan of edibles, but I don't begrudge anyone that kind of fun. I made sure the cookie tin was properly l labeled though, so that no one ate one by mistake.
This guy decided to have one after never having eaten one before. I tried to convince him not to. And an hour later, he was puking his guts up in my bathroom. We checked on him a few times, but he was in there for a good hour. He then collapsed on our couch downstairs. Also, I'm not sure what he did with one of our towels. It's missing and I haven't found it yet.
