Weight plays a role in the effects of CBD oil, and bottle size should be selected based on how much you weigh. Let’s say you weigh less than 130 pounds and desire light CBD oil effects; this means that 11 mg or less will probably suffice per dose, giving roughly 40 doses from a 450-mg concentration. If you weigh more than 230 pounds and desire strong effects, then this same concentration will supply roughly 10 doses. 
CBD products with a ratio of 20:1 or higher are recommended and administered as drops, capsules, or edibles. Specifically, products made with Valentine X or Electra 4 are more energizing, helping relieve depression. When low energy is an issue, sativa or other stimulating strains can be helpful for improving energy and focus when THC can be tolerated. Varieties that are high in the terpene limonene are recommended for mood elevation.
In the United States, non-FDA approved CBD products are classified as Schedule I drugs under the Controlled Substances Act.[62] This means that production, distribution, and possession of non-FDA approved CBD products is illegal under federal law. In addition, in 2016 the Drug Enforcement Administration added "marijuana extracts" to the list of Schedule I drugs, which it defined as "an extract containing one or more cannabinoids that has been derived from any plant of the genus Cannabis, other than the separated resin (whether crude or purified) obtained from the plant."[63] Previously, CBD had simply been considered "marijuana", which is a Schedule I drug.[62][64]
