Here are some state-of-the-art cannabis extracts I enjoyed on my last trip to Colorado. Live resin is a butane hash oil (BHO) made from flash frozen fresh plants instead of dried plants. Live resin has the terpene profile and pungency of a plant fresh from the garden. It’s a lovely hit redolent of living green.
The shatter is BHO made from dried plants. Dried plant BHO is lovely, but the fresh plant taste isn’t as forward as in live resin.
Rosin is made with a solventless technique that uses heat and pressure to turn flowers, hash, and kief into full melt hash oil. Rosin is a fast and easy technique that can make use of tools as simple as a hair straightener. Rosin extraction is simple, requiring no knowledge of chemistry or botanical extraction. Since no flammable solvents are used, rosin techniques are safer than BHO for home extraction of your medicine. The rosins I’ve tried offered a very clean hit. Rosin is a promising trend. Medicine sans solvents appeals.
