Depends on the state, the laws, and the stoner.
For me, I'd get pleasant on about 2 of them, high on 3-4, and intra-dimentional somewhere around 5-6. Down here, the state mandated edible dosage purchased to be under 100mg. So a candy bar is 100 mg : 20 pieces, a mint can is 20 - 2.5 mg mints or 20 - 5 mg optionally. That being said, our dosage laws suck the resin right off the bud. So I consider our dosages stupidly low. I dunno, I broke my edible receptor with my cookies before we got all scientific about it and counting in
@Laughing Grass' native maths. My old school cookies were two lbs of butter to two ounces of of bud and 3-5 oz of trim depending on what I had on hand. The reply I got when sharing them was, "My god you're trying to kill us."
So yeah, every time edibles come out I'm told I either "need to share" or I must have "consumed an unhealthy amount of THC to still be standing" after three times their usual dose.
I'd call them mid-dose, but they'd probably break the mind of an edible noob.
