5 benefits of pressing cannabis rosin

You may have already seen BHO and CO2 extracts with an appealing clear glass-like appearance known as shatter. Although this doesn’t make it higher quality or stronger than solventless extracts.

Rosin is becoming popular for a number of reasons:

Rosin has zero solvents

For medicinal patients who want a pure cannabis extract, the choice is obvious.

Cannabis extraction methods such as RSO, BHO and CO2, have a lengthy purging process. Where solvents must be removed from the final product, otherwise, they will leave potentially harmful residuals.

The U.S. Pharmacopeial Convention has set guidelines for what is considered safe solvent limits. However, this doesn’t include butane and propane, the two most common solvents used when extracting cannabis concentrates.

As the USP doesn’t address propane and butane, regulation is a bit like the wild west with different US states making up their own figures as to what is considered a safe limit for residual solvents.

As the illicit cannabis market is not regulated in some countries or online marketplaces, there is an even higher risk of solvent contamination.

In countries such as the UK where cannabis is still illegal, solvents are a popular method for extracting concentrates. This is mainly because they’re cheap and easy to get hold of.

You can avoid these health risks with your own rosin press machine, that uses a solventless extraction process. 

It’s safe to press rosin

It’s completely safe to extract concentrates with a rosin press. 

Other extraction methods such as BHO using butane are dangerous to both your health and our environment. 

Solvents such as pure isopropyl alcohol and butane are highly flammable, so extreme cautions need to be taken when using BHO, RSO or any other solvent-based cannabis extraction process. These methods of extracting cannabis concentrates are best done in a laboratory, not at home.

We’ve heard of too many horror stories with people attempting solvent-based extractions at home. There’ve been reports of serious accidents, fire, burns, hospitalisation, damaged property and even death! All these risks are eliminated when using a rosin press.

Pressing rosin is quick and easy

Other extraction methods such as BHO have a lengthy 120-hour purge time required to safely remove the solvents.

However, a rosin press machine is by far the quickest and easiest method for extracting concentrates.

You just load your flower/bud or hash into a micron bag in-between greaseproof paper in the press, slowly apply some pressure and collect the rosin. Then you’re ready to start vaping, dabbing or eating cannabis concentrates in no time. It really is that simple.

With a little practice, the entire rosin press process can take less than two minutes and we will teach you how on this website.

Pressing rosin is cheap

Other than the initial cost of the press, some greaseproof paper and bags you’re good to go.

Whereby with butane or CO2 you need air and pressure-tight rigs to blast wash the flowers with the chosen solvent. You then need a vacuum oven to safely purge the solvent from the solvent/oil solution produced by the wash.

This is costly in both time and money spent on equipment needed. Not to mention the ever-present health risks and fire hazards that come with using solvents already mentioned above.

As we know: failure to fully remove the solvents will result in a harsh and potentially dangerous contaminated concentrate. 

Pressing rosin requires none of this. One of the main benefits of pressing rosin is that it’s cheap to get started in comparison to these other extraction methods.

Rosin has a high THC content

Rosin is the purest cannabis concentrate as no solvents are used when making it.

Rosin also has the highest cannabinoid and terpene content. With cannabinoid concentration as high as 70% to 80% all depending on the quality of the starting product with the terpenes contributing mostly to the taste and smell of the rosin but also affecting the high when mixed with the other cannabinoids and the whole entourage effect comes into play.
