Okay, so many things (mind you this is before I watched the video in its entirety so sorry if I repeat something there) 1. Oral route for cannabis is very bad. We're talking about maybe maximum 20% of the CBD and THC you consume gets into your bloodstream from ingesting it, and your liver is already metabolising the drug right off the bat. Bioavailability is better if you consume it with something fatty 2. It can take a couple hours for you to feel the effects of ingested THC, vs a couple minutes when you inhale. The effects are less intense and last longer 3. Commercial CBD isn't typically sold at concentrations that have any observable effect, and CBD is a drug that we frankly have no idea what it targets exactly, and in pop culture it's touted as a cure-all. It isn't, most of the time what people are taking is basically CBD homeopathy because in most cases 4% of what you ingest enters the bloodstream. Apparently people also take less than 100 mg capsules, and there are no better-than-placebo treatments using CBD to my knowledge that are successful in doses less than 300 mg. For epileptic children, they can be dosed with more than 1500 mg of CBD. So it's very much possible that what you're taking is not concentrated enough to have any observable effect, and that you're less prone to the placebo effect than others.
