Cannabis Concentrates

The term ‘concentrate’ covers a wide umbrella of meanings these days, but all you need to know is that any cannabis product procured through extraction would likely be described as a concentrate.

Here are some of the most common cannabis concentrates:


Hash has been around for a long time and is well known, even among people who aren’t familiar with cannabis. Hash is made by compressing the resin of the cannabis plant. Though not as potent as BHO and other cannabis concentrates, hash remains a staple of cannabis culture around the world.


BHO is Butane Hash Oil, and is a very potent concentrate. Cannabinoids are drawn out of the plant through butane extraction, which leaves behind a wax that will either maintain its sticky consistency or harden up, resulting in a crumbly “honeycomb” or a glasslike “shatter.” This could have a potency of around 80%.

CO2 Oil

Getting this concentrate requires expensive botanical extractors that use pressure and carbon dioxide to separate plant material. This is regarded as one of the most effective concentration methods.


RSO is Rick Simpson Oil, and is named after a man called Rick Simpson who created a home remedy to help with his skin cancer. Hemp is soaked in pure naphtha and a tar like substance is left behind.


Tinctures were prohibited in 1937, but until then they were the most common form of cannabis medicine in the US. Tinctures are procured through alcohol extraction.
