If you want to learn how to make THC oil or other forms of cannabis concentrate, there are two ways of doing so: physically separating the trichome from the plant or using liquid solvents. During the physical separation process, trichome glands are removed from the cannabis starting material using a physical action, like shaking or pressing. Think of the trichome glands as fruit on a citrus tree: physical separation is similar to the shaking of a citrus tree to remove the fruit. When creating dry sift, for example, cannabis is shaken through a series of screens in specific sizes to ensure only the trichome heads make it through to the final product.
Rosin is created using a targeted combination of heat and pressure to squeeze the desired compounds out of the plant. The key concept of physical separation is that a direct physical action results in the expression of trichomes. All solvent extractions use the same basic workflow: a liquid solvent is used to separate the active compounds from the trichome gland to yield a solution. This solution must be further refined until nothing but the desired compounds remain. Due to the volatility of these solvents, technicians typically use closed-loop extraction systems, which allow them to safely control elements like temperature and pressure in order to achieve the optimal result. Due to the volatility of these solvents, technicians typically use closed-loop extraction systems, which allow them to safely control elements like temperature and pressure in order to achieve the optimal result. Depending on the solvent selected, the resulting extract is put into a vacuum oven to ensure complete solvent removal prior to consumption.
Different textures are the result of deliberate steps taken before or after the initial extraction process. In fact, many other textures, such as budder and crumble, start off as shatter. Shatter is known for its resemblance to brittle glass, which shatters on contact, but can also have a “snap and pull” consistency that gives it elastic-like properties. Shatter should be vaporized using a dab rig, and can be created using a variety of solvent extraction methods, the most popular of which include BHO, PHO, EHO, and CO2. Shatter is known for its resemblance to brittle glass, which shatters on contact, but can also have a “snap and pull” consistency that gives it elastic-like properties. The textures badder and budder are the result of agitating terpene-rich shatter into a more creamy consistency. To achieve this frosting-like texture, technicians whip the shatter under low and even temperatures to introduce and redistribute air molecules. The volume of these air molecules determines the density of the resulting texture. The textures badder and budder are the result of agitating terpene-rich shatter into a more creamy consistency. Crumble is shatter that has been whipped, like badder and budder, and then purged in a vacuum oven at low temperatures to “dry” the concentrate while retaining its cannabinoid and terpene content. Crumble is shatter that has been whipped and then purged in a vacuum oven at low temperatures. Crystalline is a transparent or semi-transparent cannabis concentrate that may resemble coarse decorative sparkling sugar or kosher salt. Multiple methods can be used to produce crystalline, but they all follow the same basic principles of crystallization. An example of crystallization is making rock candy. Rock candy is a flavored confection that’s produced when sugar (a chemical solid) is slowly added to boiling water (a liquid). The resulting solution cools a bit, then flavor and color is added. Over time, crystals form and grow on the prepared stick, eventually yielding the desired product. Crystallization is a process where a chemical solid is mixed with a liquid to create an initial solution. Any impurities are removed from the initial solution, and the extract is then mixed with another solvent under a different set of conditions to start the formation of pure crystals. Crystalline is a transparent or semi-transparent cannabis concentrate that may resemble coarse decorative sparkling sugar or kosher salt. Distillates are made by exposing a winterized and decarboxylated extract to heat and vacuum, which promotes the separation of cannabinoids based on their different boiling points.

If you've ever wondered if eating a little nug of the dank goodness you just brought home will cause the same effects as smoking it, the short answer is no.
Fresh flowers from female cannabis plants are usually smoked or vaporized for the range of mental and physical effects they exhibit, but swallowing a small bud won't do a thing to help get you high. To understand why eating raw weed doesn't get us high, we must first come to terms with what seems an impossible truth: living cannabis plants do not contain the psychoactive compound tetrahydrocannabinol (THC) that pot is famous for. Living cannabis plants and freshly picked buds are, however, abundant with tetrahydrocannabinolic acid (THCA), which is the non-psychoactive (but possibly therapeutic) cannabinoid which becomes THC when heated via smoking, vaping, or cooking. When a harvested crop is stored properly, some of the THCA slowly converts into THC, which is why so many growers subject their plants to a curation process rather than selling fresh buds to dispensaries immediately.
This process of "activating THC" is known as decarboxylation, and it is essential if you're consuming marijuana to experience its unique properties. Another reason eating raw weed won't get you high is that THC has to enter your bloodstream to reach its receptors. Marijuana isn't easy for our bodies to process, and when we eat raw flowers much of the trace amount of THC that enters our stomach is expelled through our digestive system, never to reach the bloodstream. However, if your hope for eating raw cannabis to get high stems from a desire to avoid the harm smoking may cause your lungs, you can enjoy the psychoactive properties of marijuana by eating proper edibles made with a cannabis-infused substance such as butter, oil, or alcohol.
