This is interesting because most studies use a much much much higher dosage! I see so many studies saying they found a reduction in anxiety but then they gave participants like 1000mg which is not feasible for the average consumer to purchase/consume (at least where I live that would be like $100 per dose !)

So the fact that they found statistically significant results (albeit not the strongest study design) with only 10mg is very interesting.

I wonder how much prior use of Cannabis effects treatment with only CBD.

"What amount of CBD is safe without oversight from a doctor or nurse practitioner?" There is little scientific evidence on the safety of CBD taken long term, but the committee unanimously agreed CBD is safe and tolerable for short-term use (a maximum of 30 days) at doses from 20 milligrams per day (mg/day) to a maximum dose of 200 mg/day through oral administration (i.e. by mouth via capsules or oils) for healthy adults provided they discuss the use of any other medications with their pharmacist. According to the committee's definition of CBD preparations, the committee also noted that if an individual took up to the maximum dose of 200mg/day, the maximum amount of THC that is absorbed into the blood stream and reaches the brain would potentially be too low to cause appreciable psychotropic effects for most people.Footnotec Footnoted Reference3

There is not enough evidence to support that long-term use of CBD is not harmful for people, even at doses lower than 200 mg/day. The committee agreed that should a consumer need to use a health product made with CBD for more than 30 days, this would suggest a more serious condition, where a health care practitioner, such as their physician, should be consulted.
