Cannabis concentrates are exactly what they sound like. Concentrated cannabis extracted from the plant with solvents to produce a substance containing high concentrations of THC or CBD. There are many different names for concentrates -rosin, resin, wax, shatter, budder, and others but most people don’t know what the difference is. Concentrates are created using solvents in order to dissolve and extract the cannabinoids from the plant.  Different types of solvents can be used.  

Shatter is made by using butane as a solvent and can sometimes be referred to as BHO.  It can also be created using CO2 oil in the extraction process.  The substance created is hard and brittle and can “shatter” into pieces when broken apart, which is why it is called “Shatter”. It can vary in color  from a light yellow to darker brown.

Rosin is basically just like shatter only it is not produced using solvents.
It is created by pressuring cannabis flower or kief between two hot surfaces to extract the resin from the plant.  The extracted rosin will be of a translucent color similar to shatter, and a texture that is softer and sticky.
Resin or Live Resin, is produced relatively the same way as Rosin is except resin involves pressing buds that were frozen at cultivation between two hot surfaces.  Freezing the buds after harvest helps the plant retain all its cannabinoids and terpenes so the resin that is produced contains all the same cannabinoids and terpenes of the original cannabis plant source.
If the extract you are using doesn’t come in a vape pen cartridge already, you can do ‘dabs’ with it, using a dab rig.  A dab rig is just like any other pipe, with the exception of the bowl, instead it has a “nail” that is heated up in order to vaporize the dab.  Some devices heat the nail electronically like a vaporizer, but most require the nail to be heated manually using a blow torch.  The user places the dab on the hot nail and inhales the smoke just like a pipe, with no open flame.  Sort of like the way people used to do hot knives with hashish back in the day.

If you haven’t done dabs before, remember that the dose you inhale is highly concentrated, sometimes up to 99% THC.   A single dab can provide as much THC as a couple of joints at once.
