Here’s another pertinent piece of info from the book Hashish!,
Although not all hash is the same, many types of hash are pretty darn close. Water hash – also called ice hash, bubble hash, gravity(Gumby) hash, and dry ice hash all produce forms of the same product: isolated resin glands. The difference between methods comes down to how the resin is taken off the plant, and how the hash comes out afterward.
Pretty big statement right? It’s even bigger when you consider how seriously people take hashish in today’s world!
We’ll make sure you get set up with the all the information you need, but first, let’s start things off with a picture of what we collected in under 15 minutes total!
Let’s get straight to it:
That being said, using dry ice to extract resin will leave you with nothing but the resin itself because it is solventless. The CO2 is used to freeze off the resin, and then turns directly into gas. Your trim/bud never even gets wet! So you can make hash using this method without any additional concern other than careful handling and usage of the dry ice.
- Make sure you work in a well-ventilated area.
- Dry ice turns directly into CO2 gas. Although it’s a small amount of CO2 and doesn’t really pose a threat to you, it’s better to be safe than sorry!
- Don’t put dry ice in an airtight container.
- Dry ice turns into gas which will pressurize the container it’s in. Eventually, you’ll get a top shooting off unexpectedly, or worse, an exploding container!
- Don’t touch dry ice with your bare hands
- Dry ice measures -190.3°F at its warmest. It won’t kill you to grab it, but it’s no fun to get freezer burn either.
- Dispose of dry ice safely
- If you put dry ice down your sink or toilet, you could freeze your water pipes and end up with a massive repair bill. When you’re done with dry ice, just leave it in a well-ventilated area and it’ll simply turn into gas and leave.
“Hashish is a psychoactive drug prepared from the resin glands of the female (pistillate) Cannabis plant. […]The idea is to isolate (and thus concentrate) the THC-containing resin in order to make hashish.”

How To Make Dry Ice Hash from Buds/Trim Let’s get straight to it: Making hash with dry ice is the easiest, fastest, and (more importantly) the most efficient means of extracting resin
When dry ice is added to a bucket of shredded cannabis buds and shaken, the resin glands freeze. This makes them brittle, allowing them to easily break off the buds/leaves. The trichome resin glands are collected in the normal way using standard hash collection bags. Hash bags are designed for making ice/water hash but they work great for making dry ice hash too. They can be bought online and come in a set with different sized screens, e.g. 73μ, 160μ and 220μ. Making hash with dry ice is simple and quick, and that is part of the appeal. There is no need to wait for the hash to dry, just collect it and enjoy it!
As soon as the dry ice touches the resin glands, the extreme low temperatures lock in all the terpenes and other aromatics. With the traditional water/ice method some of these aromatic compounds and terpenes are inevitably washed away and lost to the water. That’s why many of the most serious hash lovers prefer to make their own hash.
Dry ice is simply solidified carbon dioxide, or CO2. It is non-flammable and can be bought from local pharmacies. It can also be bought online and is usually delivered in special polystyrene containers which keep it cool enough to survive the overnight shipping process. Dry ice has a temperature of around -78ºC (-109ºF). It will cause severe skin damage, so wear goggles and thick gloves. Oven gloves, or similar are best, don’t expect latex gloves to protect you from such extreme temperatures.
Hash is simply the collected resin glands from the cannabis plant. Some people like to vape or smoke the non-compressed resin glands. This is called Kief. Other hash fans love to compress the resin glands to make a sticky, shiny ball of hash (cannabis resin). Usually hash has a light brown color but this varies according to the purity and type of hash. The larger the size of the ‘holes’ in the collection bags the more hash you will collect and the more leaf/green material also. However, the smaller micron sizes (e.g. the 73μ collection bag) will contain less leaf material, but a higher percentage of resin glands. The smaller the micron rating of the bag, the less chance of any green leaf material making it into your hash.
In general, the more green, leafy material in your hash the less potent it is. Usually the most potent hash comes from the bag with the smallest pore size, such as the 73μ collection bag. That’s because it usually collects most trichomes and the least green leafy material. Sometimes the hash produced from the smallest size collection bags may have a blond, or very light brown appearance.
Dry ice is a fast way to make hash. Once you have your plant material in a clean bucket with the dry ice it takes just a few minutes to make your hash which you can enjoy immediately. If you make hash with the more traditional ice/water method then you could be waiting a couple of days until the hash has dried out. During the drying of ice/water hash some of the tasty terpenes are lost. With dry-ice hash no drying is required and no terpenes are lost, you can enjoy it immediately if you wish. If you want hash with the richest, darkest and most appealing flavor you should try hash made with the dry ice method.
Put the dry ice and shredded buds/trim in the bucket. Add the dry ice pellets, put the hash bags on the bucket and shake. The dry ice rapidly cools the buds and freezes any sticky resin glands on the plant material. At these ultra low temperatures, the trichomes become brittle and glass-like. The mechanical shaking removes them, and by tipping your bucket upside down you collect the resin glands in the hash bags. The hash bags can be removed and the collected contents are tipped onto your clean work surface and scraped up. To ensure that you have extracted all the hash, repeat the process until no more is hash is removed. You can add extra CO2 pellets if necessary. You can choose whether to keep your product as loose, powdery ‘kief’ or to compress it into a ball of hash.
