Cannabis Concentrates & Extraction Methods
Cannabis concentrates are akin to the "liquor" of the cannabis world, offering a range of sophisticated products with varying potencies and qualities. Here's a detailed look at common cannabis concentrates and their extraction methods.

Solvent-Based Extractions
Hydrocarbon Extraction Hydrocarbon extraction, using solvents like butane or propane, is a popular method due to its cost-effectiveness and ability to preserve the natural terpene profile. The process involves packing cannabis leaves into tubes, flushing them with the solvent, and then heating the mixture at low temperatures to evaporate the remaining hydrocarbons. The consistency of the end product depends on the quality and terpene content of the raw material. However, there are concerns about potential trace solvents, although all products at Hashtag Cannabis are rigorously tested and come with a Certificate of Analysis (COA).
CO2 Extraction Supercritical CO2 extraction is a versatile method that allows for different end results by adjusting the heat and pressure. Widely used across various industries, CO2 extraction is considered cleaner and safer than hydrocarbon methods. However, it is less effective at preserving all terpenes because the THC in the raw material must be activated before extraction. Despite this, additional steps can capture these terpenes to restore the original profile in the final product. The initial equipment costs for CO2 extraction are higher compared to hydrocarbon systems.
Ethanol Extraction Ethanol extraction is a method that does not require heat or pressure, and uses ethanol, a solvent generally regarded as safe (GRAS) by the FDA. This method is known for its safety and is used to produce Rick Simpson Oil (RSO). Continued advancements in ethanol extraction are making it an increasingly popular choice.
Lebanese Hash
Solventless Extractions
Old School Methods
Moroccan/Lebanese Hash: This method involves sifting mature cannabis flowers through sieves to create a resinous powder, which is then compressed and heated. The result is a solvent-free hash that provides a full-spectrum high.
Finger Hash/Charas: Originating from Jamaica and India, this technique involves rubbing fresh cannabis flowers against the hands. It produces a solvent-free hash with nuanced effects.
Modern Methods
Dry Sift & Kief: Dry sift, or refined kief, is created by sifting dried cannabis flowers on micron screens. It can range from partial melt to full melt, with full melt dry sift being the most robust and flavorful.
Ice Water Hash/Bubble Hash: Made using ice water and agitation, bubble hash is rated on a 1-5 star scale based on meltability. Full melt bubble hash offers the richest terpene profile.
Rosin
Flower Rosin: Made by pressing cannabis flowers with heat and pressure to extract oil.
Hash Rosin: Created by pressing bubble or dry sift hash at low temperatures, resulting in a pure and potent concentrate.

Post-Processing Techniques
Various consistencies are achieved through post-processing techniques such as whipping, heating, and blending. For instance, concentrates with a badder-like consistency are whipped, while those with a jam-like consistency are gently heated. These techniques enhance handleability and extend shelf life.
Fresh vs. Cured Material
Concentrates extracted from fresh frozen material are termed "live" and are known for maintaining a robust terpene profile. Examples include live resin and live rosin.
