Marijuana Extracts: Hash Oil


Make Hash Oil With Marijuana And Alcohol

Following these directions, 28 grams of good marijuana buds will yield at least 4 grams, usually 5-6 grams, of one of the types of cannabis oils known as hash oil. If you grow marijuana you can turn bud trim, leftover after manicuring a crop, into hash oil.

Bud trim will usually produce less hash oil per weight, when compared with oil from buds. 28 grams of good bud trim can yield about 2-4 grams of hash oil, depending on the quality of the trim. Higher quality marijuana produces more hash oil.

Dry marijuana is ground and placed in a container where it is mixed with alcohol. After a few minutes of stirring, it is poured into a filter. The same marijuana is then mixed with another batch of clean alcohol, stirred, and poured into a second filter.

The liquid material that passes through the two filters is then heated to evaporate the alcohol. After the alcohol has all evaporated, only the hash oil remains. It can then be collected and either consumed right away, or stored for later.

Another method of producing hash oil uses butane as the solvent. Butane hash oil is not recommended for medical applications because the butane may add chemicals that are undesirable for medical use to the resulting hash oil.

The yield of hash oil made with butane is smaller in comparison with hash oil produced with alcohol as the solvent, but recreational consumers might prefer butane hash oil because it is usually slightly more potent than alcohol hash oil.

Planning And Set Up

A list of what is needed, the dimensions of the items, and an explanation of how they are employed to produce hash oil is located in the materials section of this guide.

Set up your work area and have all of your materials together. Choose a well lit area and a solid work surface that can easily be cleaned up. Make sure there is nothing near you that can ignite the alcohol fumes.

A Cooking Pot For Hash Oil Filtration System With Alcohol Solvent1) For the filtration system, you will need 2 filters made the same way.

On the bottom place a cooking pot, or other type of container that will serve the purpose of capturing and retaining the alcohol when it is filtered.

Choose the cooking pots so they have the capacity to hold enough liquid as well as support the strainers and coffee filter that will be put on them.

Strainer Placed On Top Of Cooking Pot2) Put a strainer on the cooking pot, or whatever container you use. The strainer should fit snugly on the cooking pot and be well balanced.

With an unbalanced strainer, the weight of the liquid being poured through might overturn it. This would defeat the purpose of filtering the alcohol and marijuana mixture..

Coffee Filter Placed On Strainer In Cooking Pot3) When the strainer is in place and balanced, put a coffee filter over it. This will keep any small solid particles of plant matter or other material out of the resulting hash oil.

The size of the strainers and cooking pots were chosen because a standard 12 cup coffee filter fits in well, without being short or overhanging.

Filter System For Making Hash Oil With Alcohol4) Put another strainer over the coffee filter. That is one filter, and you will need two of them.

The top strainer will filter out larger particles of plant material and foreign matter.

The coffee filter will remove smaller particles. The bottom strainer is to support the coffee filter and top strainer. The resulting hash oil will be very clean, and free of contaminants.

The material trapped by the coffee filter is mainly trichomes. When smoked or consumed in another manner, it is very potent and nearly as strong as the hash oil.

The reason for needing 2 filters, put together as described above, is the marijuana will be mixed with alcohol and filtered. This is the first flush.

Then it will be mixed with alcohol again and filtered, to remove any remaining ingredients from the marijuana. One filter will be for the first flush and the other will be for the second flush.

Marijuana Buds In A Coffee Grinder

It is suggested that you start with an ounce of marijuana, 28 grams or less for your first attempt.

Once you are familiar with the capacity of the items you use, you can increase the quantity you process at one time.

If you try to process too much material at one time, the amount of alcohol could overfill the filters or cooking pot that it filters into.

For the best results, grind the marijuana with an herb grinder, coffee grinder, or something similar until it is about the same size as marijuana that would be rolled into a joint, or a bit larger.

Marijuana Buds After 3-5 Seconds In A Coffee Grinder

Don't grind the marijuana into fine particles or powder though, that is too small.

With a coffee grinder on the coarse setting, it took under 3 seconds to grind these buds to this consistency.

After the marijuana has been ground up, put it in a freezer. You can put it directly into the container it will be mixed with alcohol in (but don't add any alcohol) and freeze it.

Also put alcohol you will be using in the freezer at the same time. Keep them there for at least 8 hours prior to making hash oil. This will limit the water soluble impurities the alcohol extracts from the mj.

Additionally, make sure the marijuana is as dry as is possible before working with it. Dry marijuana is much easier to grind and extract the potent ingredients from.


Procedure

28 grams of ground marijuana will be put in a one quart glass canning jar, mixed with enough alcohol to totally submerge it, then stirred. The alcohol will dissolve THC, CBD, and other alcohol soluble cannabinoids.

The mixture of alcohol and cannabinoids will then be poured through the filtration system to remove plant material and other impurities. This is called the first flush.

To remove any remaining cannabinoids, the same marijuana from the first flush will be mixed with another batch of clean alcohol and poured into the second filter. This is called the second flush. After being flushed twice, the marijuana can be discarded.

This can be repeated, removing the coffee filters and replacing them with new ones, in 28 gram batches until all the marijuana you want to convert to hash oil has been processed.

After that, the filtered alcohol/cannabinoid mixture that remains will be heated to evaporate the alcohol until all that is left is clean potent hash oil.

Before you start, make sure to grind the marijuana and be sure both filters are setup properly, being balanced and stable so they will stay in place and filter the alcohol when it is poured into them.


First Flush:

Ground Marijuana In A Container1) Put marijuana into a container.

In this case 28 grams of ground bud was placed in the one quart glass canning jar, that was chosen as the container to mix the alcohol and marijuana in.

A one quart glass canning jar like the one shown has a capacity of up to about 2 ounces, 56 grams, of marijuana buds that have been ground up.

Add Enough Alcohol To Completely Submerge The Marijuana2) Add enough alcohol to cover the marijuana.

It took 10 oz/296 ml of alcohol to saturate 28 grams of marijuana buds. The marijuana must be completely submerged by the alcohol in order to extract all the active ingredients.

However, it is best not to add more alcohol than is necessary to submerge the plant material, or the time it takes for the alcohol to filter and evaporate will increase.

3) Stir The Alcohol And Marijuana Mixture For 2-3 Minutes Stir for 2-3 minutes.

You can use a spoon or something similar to do the stirring. A glass stirring rod was employed for this example.

Limit the time the marijuana is in the alcohol to 2-3 minutes per flush.

If the mj is left in the alcohol for too long, less desirable water soluble chemicals are extracted in larger quantities.

4) Pour Alcohol/Marijuana Mixture Into FilterPour into first filter.

Limit the amount of plant material that gets into the filter by placing a strainer over the top of the mixing container when you are pouring it in.

Instead of a strainer, you can use something else that will serve the purpose. The marijuana will be flushed with alcohol for a second time, so you want it all to remain in the mixing container.

5) Let The Alcohol/Marijuana Mixture Flow Through The FilterWait for it to filter through.

It took about 20-25 minutes for the 10 oz/296 ml of alcohol, needed to submerge 28 grams of bud for the first flush, to flow through the coffee filter shown here.

This is the end of the first flush. While it is being filtered, the marijuana that was just mixed with alcohol and filtered should be flushed a second time by repeating the process with clean alcohol immediately.


Second Flush:

1b) Keep marijuana in the same container.
2b) Add enough alcohol to cover the marijuana.
3b) Stir for 2-3 minutes.
For Filtering The Second Flush Pour Both The Plant Material And Alcohol Into The Filtration System 4b) Pour into the second filter.

But this time pour the contents into the second filter. When pouring the mixture into the second filter, pour all the plant material as well as the alcohol in.

When the liquid is flowing through the second filter, you can speed the filtering time by raising the strainer with the plant material over the liquid in the filter. This will allow you to extract remaining liquid out of the wet marijuana.

It took about 20-25 minutes for the alcohol, needed to submerge 28 grams of bud for the second flush, to flow through the second filter.

After all the liquid has passed through the filters, the marijuana can be discarded. If you are going to make more hash oil, remove the coffee filters from both filtration systems and replace with new filters.

You can keep repeating this process for each 28 gram batch of marijuana you want to make into hash oil. Use the same containers and filtration system each time, making sure to change the coffee filters for each new batch.

When making more than a single 28 gram batch, keep the alcohol and marijuana for later batches in the freezer where they will stay cold, until they are ready to use.

If you leave them out, the alcohol and marijuana will get warm. The warmer they get, the more the water soluble materials get extracted into the hash oil.

Let the used coffee filters dry, making sure not to loose any of the contents. When the used coffee filters dry, you can collect the material that has accumulated on them.

Collecting Material On The Coffee Filter With A Glass ScraperIf you ground the marijuana into fairly large particles, rather than fine powder, the material in the coffee filters is mostly trichomes.

They are very potent and can be smoked, or if you have enough made into kiff butter.

Put one of the dry coffee filters on a hard surface, like a table, and lightly pass over the filter with something like a glass scraper.


Evaporating The Alcohol

When all the liquid has passed through the filters, and you are finished with all the marijuana you want to process, it is time to evaporate the alcohol. You can mix the contents of the two containers or you can evaporate them separately.

The liquid in the first flush container is the better of the two. By keeping them separate you will have 2 grades of hash oil.

To evaporate the alcohol you will need a heat source and something to put the alcohol in while it is on the heat source.

A cooking pot, pyrex dish, or some other type of vessel that can be heated is good for this purpose. Some people employ a rice cooker, while others choose a double boiler so the alcohol is not heated directly.

The boiling point of isopropyl alcohol is 180.7°F/82.6°C and the boiling point of ethyl alcohol is 173.1°F/78.4°C. So a heat source that can provide a higher temperature than the boiling point of the solvent you have is needed.

For a heat source working outdoors, an electric griddle will serve the purpose well. Do not use a heat source that has an open flame.

A rice cooker will also work well. It provides the heat source and the alcohol can be poured directly in, without the need for a separate vessel to hold the alcohol.

To evaporate the alcohol, turn on your heat source and if you can control the heat set it to a temperature higher than the boiling point of your solvent, while keeping the temperature below about 230°F/110°C.

Some more expensive rice cookers allow you to set the temperature. Inexpensive models will have a set temperature somewhere a bit higher than the boiling point of water, 212°F/100°C

Alcohol And Hash Oil Mixture Warming Up On Electric GriddlePut the filtered liquid mixture on the heat source. When the alcohol reaches its boiling point, you will see bubbles start to form. After it starts boiling, the alcohol will begin to evaporate.

Keep heating the alcohol until it stops boiling. As soon as it stops bubbling all the alcohol has evaporated. Alcohol/Hash Oil Mixture Boiling And Evaporating On Electric GriddleRemove the hash oil from the heat.

It took about 18 minutes for the 19 fluid ounces/362 ml of isopropyl alcohol needed to flush 28 grams of bud twice to evaporate.

At this point the hash oil is like warm tar. It should be collected while it is still warm and easy to work with. It can be consumed right away, or stored for later use.

Do not wait to remove the hash oil from the heat. If you do and it gets too dry, the hash oil might solidify and be hard to collect.

When this happens, you can add a bit more alcohol and dissolve the hash oil into it. When it is fully dissolved, heat it again to evaporate the alcohol. This time don't heat for so long.

Hash Oil Being Collected With A Chisel

The oil shown here was collected with two brand new clean chisels. One was 1/4 inch (0.635 cm) and the other was 1/2 inch (1.27 cm).

First the 1/2 inch (1.27 cm) chisel was gently moved across the bottom of the container, where the oil accumulated on the tip of the chisel. Then when needed, the smaller chisel was employed.

Depending on the material the container is made out of, a metal chisel might scratch it. So something made out of glass, silicone, or another softer material that won't scratch the bottom of the container would be a better idea.

Hash Oil Accumulated On The Tip Of A Chisel

To keep the oil warm and easy to work with, the container it is in can be put in a pot with warm water. The heat from the water will enable you to more easily amass the oil.

When a worthwhile amount was gathered on the tip of the chisel, it was put in a silicone container for storage. This was repeated until almost all of the oil was collected.

Hash Oil Being Placed In A Silicone Storage Container The storage container shown is made of silicone and holds about 5 grams of hash oil. After being filled, the top was put on. Then it was put in a fridge for long term storage.

If the hash oil is well sealed and stored in a cool dark area, like a fridge, it will retain most of its potency for 6-12 months. After that the potency will gradually decrease. But it can still be ok for about 2 years, or a bit longer.

Hash Oil On Rolling Paper After collecting all the oil it was possible to get, there was still a bit of oil left in the bottom of the container it was evaporated in.

To get the remaining oil out a small amount of alcohol was added to the container, and the hash oil was dissolved in it. When it had all dissolved and was mixed in the alcohol, it was poured into a storage container.

With the top of the storage container left off, the alcohol was allowed to evaporate into the air over the course of several days, and just hash oil remained.

Some people collect the hash oil in a plastic syringe while it is still a warm liquid. Alternately, the evaporation process can be stopped just before the alcohol has totally evaporated.

The oil will still be in liquid form when it is easy to pour into the container it will be stored in. Leave the top off of the container until the alcohol evaporates. If there is too large a quantity of alcohol remaining in the oil it can take a few weeks to evaporate without heating.

Be very careful, alcohol can extract harmful chemicals from some types of plastic, and similar materials like rubber.

Some people recommend not letting metals like aluminum, copper, iron come into contact with solvent because they can leach metals into the hash oil. However, stainless steel is safe.

When working with alcohol, make sure that it only comes into contact with ceramic, glass, porcelain, silicone, stainless steel, paper, etcetera. Containers with teflon, like t-fal, should be avoided.

The materials utilized to make this batch of oil are listed below. You might have most of them at home. If not, there are links to purchase the items in most of the descriptions.

*** strainers: To make the filtration system, 4 strainers are needed. The filters shown on this page were made by purchasing two sets of inexpensive 3 piece stainless steel strainers. Each set cost $5, for a total of $10 for six strainers.

The strainers have the following dimensions:
Large Strainer:
6.25 inches/15.9 cm outside diameter strainer
1.75 inches/4.4 cm deep
11.75 inches/29.8 cm long with handle.
Medium Strainer:
5.5 inches/14 cm outside diameter strainer
1.5 inches/3.8 cm deep
10.75 inches/27.3 cm long with handle
Small Strainer:
4.75 inch/11 cm outside diameter strainer
1.5 inches/3.8 cm deep
10 inches/25.4 cm long with handle

Filtration System For Making Hash Oil With Alcohol

To produce the filtration system, 2 filters are required, one filter for each flush. The following materials were used to make the 2 filters:
2 cooking pots
2 large strainers
2 medium strainers
2 coffee filters

To make a filter.
a cooking pot was placed on the bottom
a large strainer was placed on top of it
a coffee filter was placed on the large strainer
a medium strainer was placed on the coffee filter

Small Size Strainer Was Placed Over The Top Of The Mixing Container

A small size strainer was placed over the top of the mixing container to keep the material in the container when the alcohol was poured into the filter for the first flush.

*** marijuana: You can work with marijuana buds or any other part of the marijuana plant that has a worthwhile cannabinoid content. You will get the largest quantity of hash oil from buds.

Stems and shake from good marijuana might contain enough cannabinoids to make oil. The marijuana you process can contain seeds, but seeds do not contribute anything to oil.

*** containers: You will need a container for mixing the marijuana and alcohol in. For this batch of hash oil it was a one quart glass canning jar.

Another 2 containers are needed for the bottom part of filtration system. The filtration system shown on this page included 2 stainless steel cooking pots. They both measure 7 inches/18 cm outside diameter and 3 inches/7.6 cm deep.

You can leave the alcohol in the cooking pots or containers in the filtration system, or transfer the alcohol into a another container, to evaporate it.

*** heat source: A heat source will be required to evaporate alcohol. For working outdoors, an electric griddle with temperature control will work.

If you are going to make 2 grades of oil, you might want to heat both at the same time. Make sure whatever you choose for your heat source provides enough room. Do not use a heat source that has an open flame.

A rice cooker will also work well. It provides the heat source and the alcohol can be poured directly in, without the need for a separate vessel to hold the alcohol. Some people insist on evaporating with a double boiler.

*** coffee filters: Coffee filters are needed for the filtration system. The coffee filters for the hash oil on this page were the size made for 8-12 cup sized coffee makers.

While working on this page with marijuana bud, it took about 20-25 minutes for the alcohol/marijuana from each flush to finish filtering through the coffee filter in the filtration system.

*** storage container: If you are not going to consume the hash oil right away, you will need some type of storage container. Hash oil is very sticky, non-stick containers are a very good choice for hash oil storage.

*** well lit work area: Choose a well lit area and a solid work surface that can easily be cleaned up. Work outdoors, if you must work indoors provide adequate ventilation and vent the alcohol fumes, produced when evaporating, outdoors. Make sure there is nothing that can ignite the alcohol fumes near your work area.

*** spoon or stirring rod: Marijuana and alcohol are added to a container and mixed together in order to extract the active ingredients into the alcohol. You will need a spoon, stirring rod, or something similar to stir and mix them up.

*** 99% isopropyl alcohol: Hash oil made by following these directions will be the same as rick simpson oil, which is ingested raw to cure cancer.

If you are making hash oil for medical purposes, choose 99% isopropyl alcohol as the solvent. The resulting hash oil will contain less water soluble material than lower percentage alcohol.

For recreational or other purposes, 95% or higher ethyl alcohol like everclear, or 91% or higher isopropyl alcohol is acceptable.

Whatever your purpose, when alcohol is your chosen solvent, look at the label and make sure that the only ingredient, other than alcohol, is water.

It took 19 fluid ounces/562 ml total of isopropyl alcohol to saturate 28 grams of bud and flush it twice. 10 oz/296 ml for the first flush and 9 oz/266 ml for the second flush.

The second flush takes slightly less alcohol to saturate because it has absorbed some of the alcohol when it was flushed the first time.

19 fluid ounces/362 ml of isopropyl alcohol was used to produce 5 grams of hash oil from 28 grams of quality marijuana bud.

One gallon of alcohol would be enough to process about 7 ounces of marijuana buds and yield about 35 grams of clean and very potent hash oil.

It will take more alcohol to saturate bud trim that it does to saturate the same weight of more dense material like buds.

*** glass scraper with clean blade: The material trapped by the coffee filters is very potent. When the used coffee filters dry, collect the material lightly passing over the filter with something like a glass scraper.


Notes

1 --- With hash oil that will be prepared into food or drink, marijuana should be decarboxylated prior to making hash oil. Even if you use heat as described above to evaporate the alcohol, when oil will be made into food or drink, decarboxylate first.

Decarboxylating is so the hash oil can be absorbed in the stomach more easily. If it is not decarboxylated, the effect will be severely reduced. If the oil is going to be smoked or vaporized, there is no need to decarboxylate.

2 --- An important thing to remember when working with alcohol is that it is flamable. You should work outdoors at a safe distance from anything that might produce a spark

A spark can act as an ignition source for the alcohol. It won't explode but it can catch fire. Inhaling the fumes is also unhealthy, and prolonged exposure can lead to poisoning. If possible work outside.

If you are forced to work indoors, provide ventilation like an oscillating fan in the work area. A stove can be the heat source for evaporating the alcohol if it is equipped with an exhaust fan that is vented outdoors. To be safe, do not use a gas stove with an open flame as the heat source.

3 --- This was noted above, but in the interest of safety be very careful, alcohol can extract harmful chemicals from some types of plastic, and similar materials like rubber.

Some people recommend not letting metals like aluminum, copper, iron come into contact with solvent because they can leach metals into the hash oil. However, stainless steel is safe.

When working with alcohol, make sure that it only comes into contact with ceramic, glass, porcelain, silicone, stainless steel, paper, etcetera. Containers with teflon, like t-fal, should be avoided.

4 --- For the best results you should use 99% isopropyl alcohol and put the marijuana and alcohol in a freezer for at least 8 hours prior to making hash oil.

Start the second flush right after you finish pouring the first flush into the filter. The time from when you pour alcohol for the first flush to the time you finish pouring the second flush into the filter, should be less than 7 minutes.

This will minimize the amount of chlorophyll and water soluble material extracted. Hash oil with large amounts of chlorophyll and water soluble material will have a dark green tinge to it.

This isn't a major concern to most individuals, as hash oil with chlorophyll and other water soluble material is just as potent. But it will be an important consideration for consumers that want oil that is pure as possible.

5 --- As a cure for cancer, and for most other medical applications, marijuana with a high concentration of both THC and CBD is preferred. In general marijuana grown outdoors has a higher CBD content than marijuana grown indoors.

Rick Simpson, the person most responsible for introducing the fact that hash oil can be employed to cure cancer, recommends making medical oil utilizing marijuana grown outdoors by someone who has cannabis growing experience.

In comparison, most indoor grown marijuana has higher concentrations of THC but lower levels of CBD. This is fine for most spiritual or recreational consumers of hash oil.

However, if you are growing indoor marijuana to be made into hash oil for medical purposes, especially to cure cancer, choose an indoor marijuana strain that will produce marijuana with a high CBD content, in addition to high levels of THC.
