How much THC did they give the rats compared to human quantities? I read an article about monkey brains showing some type of symptom when they looked at white matter under a microscope. Turns out the poor monkeys were given the equivalent of an adult smoking a pound a day.

I also don't the THC content of weed, but it doesn't sound like an unfathomably high dose. I think the other design concerns are more likely to be the culprit here than external validity worries about dose.
- eisrep 7y agoJust for reference, your average edible will come in a suggested dose of ~10mg THC per piece.
- jjjensen90 7y agoNormal weed "flower" is 10-30% THC. So 1 gram of weed is 100-300ish mg of THC. A single prerolled joint is usually 1 gram of flower. So this dose is around 1 joint. Edit: importantly this info is for smoked flower, edibles and concentrates are a little different because of how they are absorbed.
- loeg 7y agoSmoking an entire 1g preroll by yourself is a huge dose for a human who doesn't have a high tolerance.
- filoleg 7y agoI mean, it would depend on the THC concentration, right? A 1g pre-roll with 30% THC would be 3 times as potent as the one with 10%, so I can totally see someone with rather low tolerance smoking a full 10-12% joint by themselves and feeling just fine.
- pault 7y agoThere is a scaling factor between mouse and human dosage that I can't remember off the top of my head, but it's not 1:1.
- Pete_D 7y agoStudy says: "... we modeled PCE by administering THC (2 mg per kg, subcutaneously (s.c.) once daily) to rat dams during pregnancy (from gestational day (GD) 5 until GD20). This low THC dose does not recapitulate behavioral responses in the can-nabinoid tetrad assay or elicits cannabinoid tolerance after repeated administration, hence it represents a mild insult without any substantial direct impact on maternal behavior. ... In terms of human consumption, this dose is equivalent to THC content in mild cannabis cigarettes (joints) (5%), since the average THC content in illicit cannabis preparations has significantly increased in the last two decades (from ~4% to ~12%)."
