The present disclosure generally relates to terpene-based compositions for applications in the pharmaceutical and recreational fields. In some embodiments, the compositions are enriched compositions or non-naturally occurring compositions which contain defined concentrations of one or more cannabis-derived chemical compounds, such as terpenes and cannabinoids that have a distinctive characteristic that mimics that of a cannabis plant matter or a product thereof. Also provided in some embodiments of the disclosure are methods for the preparation of the compositions, as well as methods for use thereof.

The invention relates to the process for producing an microemulsion system of nano essential oil, the process comprising the following steps: (i) preparing a dispersed phase of essential oil; (ii) preparing of a carrier formed from a mixture of diethylene glycol monoethyl ether and lecithin; (iii) adding the carrier to the dispersed phase while keeping the dispersed phase temperature between 60 and 100° C. after addition of the carrier, while simultaneously stirring under vacuum; then pass the entire solution mixture through the system of high-pressure homogeneous machine integrated dispersion nozzle; (iv) adding the solution mixture obtained in step (iii) to Capryol 90 while keeping the mixture temperature between 60 and 100° C., and stirring at a rate ranging from 400 up to 800 rpm under vacuum; (v) cooling the mixture, homogenizing the mixture by ultrasonication to achieve a droplet size smaller than 100 nm.

Disclosed are compositions and methods for measuring olfactory sensitivity, olfactory resolution, and combinations thereof. Such measurements can be made during a single test, or over consecutive tests, which may be performed during a single testing period, such as in a single day, or over a series of testing periods. The tests may be performed by a health care professional, or may be conveniently self-administered by the user.
