1. A process for obtaining a first extract of Cannabis sativa, Cannabis indica, or combination thereof, enriched with at least one of: cannabinol; cannabinolic acid; Δ(9)-tetrahydrocannabinolic acid; Δ(9)-cannabidiol; Δ(9)-tetrahydrocannabidiolic acid; Δ(8)-tetrahydrocannabinolic acid; Δ(8)-tetrahydrocannabidiol; Δ(8)-tetrahydrocannabidiolic acid; Δ(9)-tetrahydrocannabivarin; cannabigerol; cannabigerolic acid; cannabichromene; cannabichromenic acid; cannabicyclol; and cannabicyclolic acid, and
a second extract of Cannabis sativa, Cannabis indica, or combination thereof, enriched with at least one of Δ(8)-tetrahydrocannabinol and Δ(9)-tetrahydrocannabinol, the process comprising:
(a) contacting Cannabis sativa, Cannabis indica, or a combination thereof, with carbon dioxide as the sole supercritical fluid solvent, at a pressure of 1,600 psi to 3,800 psi, at a temperature of 44° C. to 54° C., for a period of time of 2 hours to 8 hours, to provide an enriched extract of Cannabis sativa, Cannabis indica, or combination thereof; and
(b) removing the supercritical carbon dioxide from the extract; wherein the (a) contacting of the Cannabis sativa, Cannabis indica, or a combination thereof, with the supercritical carbon dioxide and then the (b) removing the supercritical carbon dioxide, is carried out two or more times, such that the process is a supercritical carbon dioxide fluid extraction;
wherein a first supercritical carbon dioxide fluid extraction is carried out such that:
(i) the contacting of the Cannabis sativa, Cannabis indica, or a combination thereof, with the supercritical carbon dioxide, is carried out at a pressure of 1,600 psi to 2,000 psi, at a temperature of 44° C. to 54° C., for a period of time of 2 hours to 4 hours, to provide the first extract;
wherein a second supercritical carbon dioxide fluid extraction is carried out such that:
(i) the contacting of the Cannabis sativa, Cannabis indica, or a combination thereof, with the supercritical carbon dioxide, is carried out at a pressure of 2,250 psi to 3,800 psi, at a temperature of 44° C. to 54° C., for a period of time of 4 hours to 8 hours, to provide the second extract.
