Distillation is a method used to purify cannabis extracts by separating the individual compounds based on their boiling points. One common method used to create cannabis distillate is called **short path distillation**. This technique involves heating the cannabis extract to vaporize the THC and CBD, then bringing the vapor into a cooling system for consolidation and eventual collection into beakers².
To make cannabis distillate, the cannabinoids, terpenes, and flavonoids must first be extracted from the plant using a solvent such as ethanol or CO2. The cannabis must be dried to 5-15% water content, shucked from the stems, and ground to 2-300 microns for more efficient extraction¹. Once the extract is obtained, it can be distilled using a short-path distillation unit to separate the THC from other compounds¹.
Short path distillation and fractional distillation are two methods used to purify and separate compounds based on their boiling points. Both methods involve heating a mixture to vaporize the individual compounds and then condensing the vapor back into a liquid.
The main difference between the two methods is the distance that the vapor travels before it is condensed. In short path distillation, the vapor travels a very short distance (typically just a few centimeters) before it is condensed. This short path length reduces the amount of distillate that is lost during the process and makes it more efficient for distilling small quantities of material².
Fractional distillation, on the other hand, involves a longer path length for the vapor to travel. The mixture is heated in a flask and the vapor rises up a fractionating column before it is condensed. The fractionating column contains packing material that provides a large surface area for the vapor to condense on. As the vapor condenses and re-vaporizes on its way up the column, it becomes increasingly enriched in the lower boiling point compound⁵.

Processing Marijuana:
1. Introduction: As the cannabis industry transitions from a black market to a legal market, product development and methods of extraction have become a focal point. However, scientific publications that explore these areas for the cannabis plant are currently lacking¹.
2. Method: This is a narrative review paper which focuses on critiquing drying and extraction methods of Cannabis sativa L. plant. Relevant keywords such as medicinal cannabis, extraction, solvent, cannabinoids, and terpenes have been searched in PubMed, EMBASE, MEDLINE, Google Scholar, and Cochrane Library (Wiley) databases¹.
3. Result: Based on this review, solvent extraction is the most common method for cannabis plants. Although solventless and hydrodynamic extraction are known for their high yield and feasibility, more investigation is needed in these areas. Regarding the drying process, hang-drying is the most convenient method; however, it may be substituted by freeze-drying in the near future¹.
4. Discussion: This review analyses various drying and extraction processes to guide the selection of suitable methods for various types of cannabis products and applications. This is done by outlining traditional and modern methods of drying techniques, exploring the importance of solvents for extraction, visiting solventless extraction procedures, and finally comparing conventional and alternative methods of extraction¹.
4.1. Introduction: As the cannabis industry transitions from a black market to a legal market, product development and methods of extraction have become a focal point. However, scientific publications that explore these areas for the cannabis plant are currently lacking.
4.2. Solvent Extraction: Solvent extraction is the most common method for cannabis plants. This section would explore the different types of solvents used and their effectiveness in extracting cannabinoids and terpenes from the cannabis plant.
4.3. Solventless Extraction: Solventless extraction methods such as rosin pressing and dry sifting are known for their high yield and feasibility. This section would explore these methods in detail and compare their effectiveness to solvent extraction.
4.4. Hydrodynamic Extraction: Hydrodynamic extraction is another method that is known for its high yield and feasibility. This section would explore this method in detail and compare its effectiveness to other extraction methods.
4.5. Comparison of Extraction Methods: This section would compare the different extraction methods discussed in the previous sections and provide guidance on selecting the most suitable method for various types of cannabis products and applications.
5. Conclusion: In conclusion, based on the current knowledge, using organic solvents is the most convenient method for medicinal cannabis extraction. However, more research is needed for some of the drying and extraction methods. Also, developing a green and sustainable cannabis extraction method should be considered for future studies¹.
