What is hashish: You need to know about extractions

It is in this concentrate that magic happens! Understand the different types of hashish and why this extract is filled with cannabinoids and terpenoids has been gaining so much space in cannabis culture

Cannabis lovers do not only consume flowers, hashish is a very common choice amongst its users made by many who want to experience different terpene profiles. In addition to being a possible experience to taste the famous ganja terroir, as in good wines, this magical resin presents the potential of cannabis concentrated in a small ball.

Made using different techniques in order to separate the trichomes (that sparkling crystal) present on the plant away from the rest of the plant matter, hashish is nothing more than a mass of cannabinoids and terpenoids. It is in this concentrate of trichomes that the magic happens.

Currently, the regulated market in some countries has already opened the door to explore the world of extractions and different types of hashish. But the past of this substance is extensive – it can be traced back to the 18th century by Middle Eastern and African cultures, and even earlier in religious rituals – used as a medicine, a mystical and even an aphrodisiac drug. 

The different lands, environments, varieties of cannabis plants and ways in which they are managed (cultivation, harvesting, maturity) offer a huge range of what this heap of trichomes might look like – there are hashish of all colors: brown, black, red, yellow , and even white with new North American technologies. In its extensive variety, we believe in the importance of knowing how to differentiate extractions and Hashish – mainly within the irregular market. We know how difficult it is to trust past information, but with your trained eyes and nose you won’t fall for anyone’s tricks! Luckily cannabis, unlike other substances, we can use our visual, olfactory sense and feeling, its touch, we can know a lot about the quality.

Hashish has an extensive past, but in the modern world, with the increase in technology, new ways have been developed to be able to isolate cannabinoids from plant matter (hash contaminants). These techniques can be divided into 2 large groups, those that use SOLVENTS for this separation and those that do NOT.

It is not new that Girls in Green, always gave preference to extractions and Hashish that were made without the use of solvents: after all, why chose a technique that uses solvents while there are great ones that only use mechanical separation? Solventless extractions are more natural, cleaner and safer, and a harm reduction approach towards cannabis extracts.

However, we will not stop addressing the extractions made with solvents, such as the famous BHO (oil made with butane). We know that to reduce any kind of risks and harm, nothing better than giving quality information for conscious and responsible decision making.

Are you ready?

Solventless Extractions (or Sieving)

Our favorite kinds are  HASH is part of the solventless category, the trichomes are separated only though mechanical separation, without the use of any solvents in its processes – thrichome heads are sieved. Generally, trichomes are separated with different micron screens and use only different combinations of pressure, temperature and using only pressure, temperature and water.

Main types of hash without solvent:

Bubble Hash, Water Hash or Ice-O-Lator
Bubble Hash, Water Hash or Ice-O-Lator

Bubble Hash

The bubble hash (famous ice-o-lator) is made using only filter bags (like Bubblebags, which can be found on this link), water and ice. As cannabinoids are not soluble in water, the agitation of the material, be it flowers or even trim, is enough to separate the trichomes from the plants. The trichomes will remain loose in the water during washing, and after the end of each cycle, they will be collected in the filter bags. Is it complicated to imagine that? Then take a look at the small tutorial we set up with our Overgrow Shop partners: “Mini Tutorial on how to make Bubble Hash


Do you want to know a curiosity about our favorite, hashish? The bubble hash, when heated, it bubbles! This is also a sign of quality control: when it bubbles and melts it is crema, and when it catches fire and gets darker, it is a sign that there is greater contamination of plant matter.

Obs .: there is a big question in the Hashish universe where some claim that water is a solvent. Yes, we know that water is a solvent, but in this case, it is not being used as a solvent – just a tool.

Dry Sift

Dry sift, or dry hash, takes its name from its process (dry sift is, literally, sift through dry). The raw material is agitated and sieved on fine-meshed screens, which separate the heads of the trichomes by different micragems and result in a granular texture material. Some of its main benefits are the results of the artisanal and chemical-free process, which preserves a differentiated terpene profile; high power and quality; it also gives you the ability to melt and vaporize completely if it’s done well!

This is one of the most traditional ways to make hash used by Middle Eastern, and African culture. Even today, countries like Morocco, supply a large part of the global demand for hash traffic (even for countries with tolerance to cannabis use, like Holland and Spain, can you believe that?). These photos were taken on cannabis farms in northern Morocco, where we learned a lot about the more traditional ways of producing dry sift hash for years.

The most diverse techniques were used to produce Hashish in Morocco, Lebanon and the Himalayas – for those interested, it is possible to mix this theme in books such as: “The Great Book of Hashish” or even the book “Hashish!” Robert Connell Clark.

Flower Rosin

This is one of the easiest ways to make a concentrate simply, quickly, cheaply and safely indoors. Only heat and pressure are used to separate cannabinoids from the rest of the plant matter. There are very rudimentary ways to do it, such as using parchment paper, filter bags and flat iron (yes, your sister’s hair flat iron!), And there are more technological strategies, such as with presses, better known as rosin press , which allow the regulation of pressure and temperature.

Hash Rosin

The process is basically the same as that for obtaining the Flower Rosin, with one difference: instead of using the flower, you use the hashish itself. So, you basically have a double refinement. If done right, it gives rise to a very high quality hash!

We at Girls In Green did an experiment pressing a Moroccan hash and seeing what comes out of it! Curious? Take a look here at this link on our IGTV.

Solvent extractions

Solvent processes use other substances to separate the trichomes from the rest of the plant. Some of the main ones used are CO2, butane, organic ethanol and propane, but there are several others.

Such methods offer two risks: for those who do, the risk lies in dealing with highly flammable or explosive materials; for those who consume it, the risk is in possible leftover solvent in the hash. Whoever uses this method should pay close attention when purging the solvent and leaving the hashish 100% pure and clean.

This one in the photo is a hash from @bamf_extractions, taken in 2017 in California. The Brazilian Hash Maker has already taken numerous awards home with his extractions, and is one of the few people that we still give the chance to smoke some extraction with some solvent.

Be very careful when dealing with any kind of solvents! If you decide to do it at home, choose an airy environment and do it with the right materials! It is always good to watch tutorials on Youtube to ensure everyone’s safety (yes, many cases of explosions during home production of, for example, BHO – extraction using butane). Without them, you will be putting your life (and others’) at risk.

The results

Extracted through different processes, the quality and potency of the hash depend not only on the extraction, but on the entire process of cultivating cannabis. If the raw material is first class, the greater its concentration of cannabinoids and terpenoids will be. We can only sieve and extract good material, if it has been grown well and matured.

The hash can be soft and flexible, or rigid and brittle. It can be white, reddish, black, brown, or yellowish. It is as varied and full of specifics as our beloved cannabis, and that is one of the reasons why we like it so much. 

Hash effects

Today, with the advancement of technology, we can even find cannabinoid crystals concentrated with 99.9% THC. This is not the type of commercial hashish, but it does show that as it comes from trichomes, there is a higher concentration of cannabinoids than when compared to a flower.

The effects of hash consumption can be much more intense than Cannabis flowers. Therefore, for people with little experience or tolerance who make the decision to use, start slowly and wait to repeat. It is probably best to consume a small test and see how your body reacts?

How is it consumed?

There are many different ways to consume hash and its varieties. It is possible to mix a little of it with the herb itself, with flowers, with tobacco, and even with kumbayá and smoking in the form of a cigarette. When it is more liquid /oily, many people use it in the bowl, as a “cover”, so to speak. Bongs, pipes or vaporizers for those who want to eliminate the combustion process as a Harm Reduction strategy. It is a matter of preference, and just experimenting to know which one will adapt best to your way of consuming.

Our tip is, just like cannabis itself, consume in vaporizers or bongs for Harm Reduction – as they allow you to burn without burning. Hash can also be added to butters and oils to make cannabis edibles. (Check out our post on making cannabis infused Brigadero – Chocolate Fudge here).

Regardless of your favorite hash type: it has to be done safely and with quality material! So always keep an eye on what you are using – this is the best tip for harm reduction when using cannabis and its derivatives.
