In the United States, non-FDA approved CBD products are classified as Schedule I drugs under the Controlled Substances Act. 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." Previously, CBD had simply been considered "marijuana", which is a Schedule I drug.
Effective in January 2017, the DEA (which typically refers to marijuana by the plant’s scientific species name, Cannabis sativa, or the Reefer Madness-era spelling “marihuana”) made a rule stating its marijuana scheduling includes “marihuana extract.” In the rule, the agency defined “marihuana extract” as an “extract containing one or more cannabinoids that has been derived from any plant of the genus Cannabis”—which would include CBD.
Generally speaking, most marijuana producers and sellers (especially on the black market) don’t test for contaminants (metals, pesticides, bacteria, etc.). Rick Simpson Hemp Oil is actually more a method of extraction than it is a specific product. People use the Rick Simpson method with hundreds of different strains of marijuana, so the THC, CBD and other cannabinoid content of the final oil always vary greatly, depending on the cannabis the consumers are acquiring. Usually what’s used for Rick Simpson oil is a strain with an inferior CBD content (and high THC), because that’s what the vast amount of marijuana is nowadays.
