First off, every individual human body has a different rate of metabolism and reserve capacity for cannabinoids. So this outline is based on experience and not on studying carefully controlled dosages with blood work unfortunately.
We have found that is takes 3-5 days of regular use of at least 50 mg per day to saturate the body. After this saturation point is hit then the user has noticed positive effects from the products for up to 3 days after taking their last dose. This seems to be the body using up the residual cannabinoid content in the body and can vary from person to person.
This fun fact has helped me to keep a somewhat consistent amount of CBD in my system on quick business trips where I forget to bring my tincture.
