I mean my first edible ever was 500mg, and I consider that my first ever psychedelic experience. It's never hit me like that since, but it used to hit me like a normal-ish person

Edit: and for reference, I'd go through about an ounce of distillate a week on edibles alone back when I was dealing. I'd say I probably ate at least 1/3 of that minimum, not to mention taking dabs and smoking blunts 24/7.

Someone that takes anything like they're a junkie can develop tolerances far beyond what anybody else can. Back when I was into opiates, I knew people who would take 2x the dose my Grandma got when she was on hospice just to stay out of withdrawal. My opiate tolerance never got that high, but still. My brain has the tolerance of someone that used drugs to get fucking blasted
