I've been using recreationally for 20 years and a 10mg edible still hits me plenty hard. 20 would hit me like a donkey kick, 60 would make me extremely uncomfortable to say the least.
Lucky. You can add a 0 on the end of those for me, more than that at the high end. I've done 1000mg over the course of ~12 hours before. Now, admittedly I wasn't DOING a whole lot in those 12 hours (mostly watching movies), but I was functional enough that if called upon to do so I could have had a coherent conversation.
