There are a ton of names when it comes to cannabis concentrates, whether they refer to how they were processed, i.e. BHO, PHO, ISO, CO2, Distillate, or the quality of the product that comes out of the process, such as Budder, wax, oil, shatter, moon rocks, etc.

One thing that remains the same between all of these is that the products are all highly concentrated cannabis oil. Yes all concentrates are the extracted oils from the plant, it initially contains other unpleasant things such as plant lipids, chlorophyll, etc. but through the process of extraction and refining we are left with a golden or amber oil, some can be very light, almost clear with a hint of color, and some can be very amber.

There are many factors that determine the final quality of today's concentrates, they really are a melding of science and art. Yet the fact remains, it is still cannabis and they are amazingly potent. They can be used as is, such as for dabbing.
Or they can be combined with other ingredients to make everything from capsules to gummy bears. So if you have the opportunity to try some lovely concentrates I would recommend it. Talk to you local bud tender and they can help you choose the right extracts for your wants/needs. Remember, a little dab will do ya!
