Cannabis extract is concentrated cannabis. It’s much more potent than the cannabis buds themselves. The words “cannabis extracts” cover a wide array of products, including vape oil, tinctures, and hash. They can be used in vaporizers, ingested, or added to topical creams or balms and used to treat a variety of ailments.
When made correctly, cannabis extracts are reminiscent of the strain they were derived from. The scent, flavor, and effects are magnified in the concentrated extract. Furthermore, the way cannabis extracts are made varies based on the type being created.
With an alcohol extraction, cannabis is soaked in alcohol, commonly ethanol. After being soaked, the plant material is removed. The resulting liquid is filtered and the alcohol is evaporated out.
The temperatures are controlled carefully during this extraction method, especially during the evaporation phase. One of the biggest benefits of alcohol extraction is that no residual toxic chemicals are left in the final product. At the same time, cannabinoids and terpenoids, the desired compounds, remain.
Butane extraction involves pressurizing and heating cannabis and liquid butane. Under a vacuum, the butane liquid turns into a vapor, allowing it to be easily removed. Lastly, temperatures are carefully monitored to avoid an explosion.
The resulting product of butane extraction is butane hash oil. All butane must be removed from the final extract. One of the biggest benefits of this extraction method is that the extracts are flavorful and have high terpene contents.
Cannabis Extract from CO2 Extraction
CO2 extraction is an extraction process that uses carbon dioxide to extract cannabis components from the plant material. With supercritical CO2 extraction, the temperature and pressure create phase changes in the carbon dioxide. Therefore, giving it the properties of both a liquid and a gas. The CO2 forces the desired compounds out of the plant material based on their weights.
Once the components are extracted, the CO2 goes into a condenser and becomes a liquid that can be filtered and reused. Any CO2 remaining in the extract simply evaporates out on its own, guaranteeing that there is no residual solvent in the final product.
Dry sift, or dry sieve, is a solvent-free extraction method. It involves breaking the trichomes away from the flowers by running them through a series of screens until only the trichome heads are left. Furthermore, the highest quality product contains no plant material and should melt completely when exposed to heat.
Kief is a lower-quality version of a dry sift extraction. The plant material is sifted through filtering screens. As a lower-quality product, it may still have some plant material remaining. Even so, the best extractors can create clean and flavorful final products.
There are two extraction methods to make hash. One involves freezing the buds and then breaking them into pieces. Then sending them through a screen to separate the trichomes which are then pressed into a block. The other method is to use ice water to separate the trichomes. Once dried, the trichomes are pressed to create a block of hash.
Rosin is a solvent-free extraction method that has gained popularity in recent years. It’s a solid form of resin that involves adding heat and pressure to vaporize liquid terpenes. The process is simple and quick, allowing for the extraction of cannabinoids and terpenes without the risk of leaving behind any harmful solvents.
Cannabis extracts have numerous applications and can help to treat a broad array of issues. If you’re interested in learning more about cannabis extracts and finding the right one for you, a licensed dispensary can help to guide you toward the right solution.
