I recently shared samples for the new CBD derivitives, Delta-8 THC and Delta-10 THC. I told my friend to only take half. Being an arrogant asshole, he ate the whole thing. In short order, he was hallucinating and babbling incoherently. I felt bad, but also pissed that he didn't listen. Maybe I shouldn't have expected him to. So yeah, always go slow on edibles. Always.
