How to extract THC and all its uses

Learn the most commonly used homemade methods of extracting the purest THC

THC (Tetrahydrocannabinol) is the main psychoactive constituent of marijuana or cannabis. Knowing how to extract and process THC safely are both a technique and an art, and today we’ll give you a brief summary of the different methods to do so.

If you are under 18, please do not continue reading. This information is for ADULTS only. We will never incite to the consumption of narcotic, alcoholic or addictive substances in minors.

As we have told you before, you will not be able to buy THC oil, having said that, it’s time for you to know the different ways to extract and make THC. We won’t use complicated technical terms, with the word “Tetrahydrocannabinol” we have had enough, but we will do our best to use an easy and understandable vocabulary for everyone.

🔥 How to extract pure THC ?

There are several techniques and methods for extracting THC. Some allow excellent purity margins, even close to 100%, while others offer resin with 60% purity. Although the methods may be artisanal, behind them lies a whole science based on chemistry.

Extraction of pure THC is feasible only if the right methods are used. The best way is through mechanical extraction methods. With this methodology the percentage of hashish THC is usually high in purity, as long as you apply it correctly.

THC extraction can also be done by physical-chemical methods, which are often more complicated and sometimes dangerous. In this case we are talking about processes of extraction and not just separation of hashish THC.

First, let’s see how to extract THC by physical or mechanical methods:

How to extract THC from dry marijuana by mechanical methods

We don’t want to fall into theoretical issues, but you should know that this aspect is important. Marijuana, like any vegetable, has its conditions when it comes to sowing and harvesting. If you want to extract hashish with high quality THC you must not neglect any detail.

The idea of this method is to be able to extract the best trichomes of the plant (a trichome is a very small part of plants and, speaking of marijuana, they are very important since they concentrate great part of cannabis’ properties).

How to extract THC from dried flowers:

  1. The first thing is that you must have the marijuana buds dry and well conserved. This is done in hermetically sealed glass containers, although you must open them to air them during the first 5 days.
  2. Also there are methods where they are frozen. In this way the properties of the substance are preserved intact. But to keep it without freezing implies a process of maturation and cured of 4 to 6 months.
  3. This method consists of sieving and repeating the sieving by means of meshes of different sizes, using dry flowers. This can be done by manual shaking or with machines.
  4. With the dried flowers, we follow a sieving process that allows us to take as many trichomes as possible. We can use silkscreen meshes, ideal for filtering out “garbage” and keep the best.
  5. The first mesh of 160 microns will be the starting point for the basic hash. From there it will go to an intermediate mesh of 70 microns. What remains here is “the best of the best”. All that’s left is to pass it through the 45-micron mesh, and what’s left there will be the “second best”. The remains that pass are of “third quality”.
  6. This is the rough explanation. The sieving process can have variations in the number of meshes, and it’s assumed that the greater the number of meshes, the better the result. Some tools use a system of 190 – 160 – 70 – 45 – 25 (where anything less than 25 and more than 190 is discarded).

Summary of how to extract THC from dried flowers, is a simple method

This is a basic method for dry pure THC extraction, by purely mechanical means. The variant of doing it with frozen flowers is not very different.

At the end, you must collect the trichomes with a card and store them in resin form through a pressing process.

🎯 How to make homemade THC ?

There are many ways to make homemade THC. In practice we can say that the various methods that exist for making THC can be considered “homemade“. So far, the legal status of cannabis in the world has not been favorable to manufacturing THC at an industrial level.

But if we had to define a classic way of making homemade THC, we would keep the traditional methods of sieving, bubble hash (hashish made with water and ice), pressing and any other method that allows the extraction of cannabinoids and terpenes by mechanical means.

We have already seen a homemade method of dry THC extraction. Now we will see how to extract hashish THC with ice and water, the famous bubble hash.

Get the following materials:

  • 2 buckets.
  • Ice and water.
  • Kit of meshes.
  • Strainer.
  • Any object or device that allows the mixture to be blended (drill, mixer, etc.).
  • Pyramid-shaped bag for storing weed.
  1. Put the weed into the freezer, at least 30 minutes before starting the process.
  2. Fill one of the buckets up to 1/3 of the volume with water, preferably cold water.
  3. Fill half the volume of the bucket with ice. We want to achieve a temperature between 1º and 4º.
  4. With buds or remains of grass well shredded, proceed to put them in the pyramidal bag.
  5. Put the bag inside one of the buckets. Start beating with a mixer, or whatever it is that is used to give movement to all the vegetable matter in the water. When finished, take the other bucket and put the meshes in ascending form, from the smallest to the largest.
  6. Wear gloves to protect your hands from the cold and proceed to filter the ice and water. Press the meshes to pour the water, taking care to prevent plant debris from entering the meshes. If they release foam, you can add water to rinse, and then press by hand.
  7. The final step is to convert the resin into powder to make it easier to dry. This is where the use of the strainer comes into play. You must use a cardboard covered with baking paper where you will collect all the powdered resin. Then, just let it rest until it dries.

To press the mixture, you have to wait from 20 days to one month of drying. This is the basic way to extract hashish THC with ice and water.

✨ How to make synthetic THC ?

You may have heard about k2 spices and synthetic marijuana. This is an artificial THC substance that has nothing to do with natural marijuana. If you want to know how to make synthetic THC you will have to become a chemical specialist (a Walter White), as these are laboratory drugs.

In specialized laboratories synthetic cannabinoids are manufactured, which seek to emulate the effects of natural marijuana in a safe and legal way. But, apparently they are very dangerous drugs since their long-term effects on the organism and the cerebral receivers are unknown.

⭐ How to extract THC for cooking ?

Marijuana can be a real culinary delight. The important thing is to know how to extract THC to cook, so we can add these concentrated in different menus, and they will have a “special” effect.

In this article we have shown you several ways to extract the best trichomes that give you the purest hashish. Now we’ll see a way to extract drops of THC that can be added as oil to meals.

With these methods you won’t have to buy liquid THC, although it’s a good option if you want to save time making your recipes.

You can extract THC for cooking in the following ways:

  • Marijuana flour: the bud or leaves of the cannabis must be dry and have been cleaned thoroughly. You grind them with a chopper and then with a grinder until you get a very fine powder. With this flour you will be able to prepare diverse recipes.
  • Extracts: this involves removing the THC from the trichomes of the plant and set it in some suitable substance in the form of resin. The substance can be greasy like butter, oil or alcohol.

How to make E-Liquid with THC ?

Vaping marijuana in the form of eLiquid with THC and CBD is one of the great pleasures of life. The best thing is that we can make this liquid ourselves with few materials in our own home.

A necessary step is to heat alcohol, so please take all possible safety measures and don’t be careless.


  • 2 large glass jars.
  • 5 to 6 gr. of high quality buds.
  • Large pot for boiling.
  • Container with 5 ml dropper.
  • Food grade propylene glycol.
  • Ethyl alcohol or ethanol (high-grade alcohol. Never use common disinfectant alcohol).
  • Syringe 5 – 10 ml.
  • Baking tray and aluminium foil.
  • Gloves and safety goggles.

Material to make E-Liquid with THC


1. Decarboxylation of marijuana. It’s a chemical process that you can’t skip to activate THC. You must finely chop the buds and put them 15 minutes in an oven at 105 – 110º.

Steps to decarboxillate marijuana

2. Put the decarboxylated cannabis in one of the glass jars and fill it with high grade alcohol.

Put the decarboxylated cannabis in the bottle with the alcohol.

3. Evaporate the alcohol. This is done in a bain-marie with half a liter of water in the pot and introducing the jar until the alcohol evaporates and the mixture becomes dark. Remember to be careful with temperature and alcohol.

With the bain-marie method, alcohol evaporates.

4. Add more alcohol until you reach the original level.

Then you’ll have to add more alcohol

5. Take the other glass container and pour the mixture while using a cloth to strain the buds. Return to step 3 until only 5 ml remain.

Use the strainer cloth to strain the sprouts several times.

6. Prepare the mix. Add 20 ml of propylene glycol and mix well. You should get 25 ml of THC E-Liquid from your 6 gr. of marijuana.

Add propylene glycol and mix

How to make oil with THC ?

The procedure we have just shown you is the standard variant to make medical marijuana oil for pain or any use you want. Next we will tell you a well-known alternative procedure.

Materials and ingredients are as follows:

  • 1 1.90 litre bowl or container.
  • 1 Ceramic or glass medium bowl.
  • Large wooden spoon.
  • Silicone spatula.
  • Oral syringes.
  • Bain-marie pot.
  • Gloves and safety equipment.
  • 29 grs og marihuana.
  • 1 gallon of high-grade alcohol for human consumption. Everclear recommended.

Ingredients for making medical marijuana oil


1. Put the cannabis buds in the glass container and then fill the jar with the high-grade alcohol solvent until it is 1 inch or 2.5 cm from being filled.

Add alcohol in the jar where you already have the buds of cannabis

2. Mix with the spoon, crushing the weed with the solvent for 3 minutes.

Use the spoon to crush the mixture.

3. Strain the mix of marijuana with solvent in the other container.

Spread the marijuana mixture to another container through the strainer.

4. Soak, stir and strain the solution a second time.

Repeat the 3 previous steps

5. Evaporate the solvent alcohol in a bain-marie. Add water to the bottom of the pot. Add the dark green mixture. Turn on the stove and start heating. When bubbling, turn it off and let it evaporate on its own. Continue and clean the sides with a spatula.

Put the mixture in the bain-marie so that the alcohol evaporates.

6. When you see only a dark green liquid, the solvent will be evaporated. That’s your THC oil. As it cools, it will become thicker.

The solvent will be evaporated when the mixture turns dark green.

7. Store your oil in the syringe.

Store your oil in a syringe for oral administration.

⛳ Conclusion

We have seen some general procedures on how to extract and make THC at home. It’s time for you to experiment on your own, but it’s very important that you understand that the procedures or system you use are worthless if you don’t have a good raw material.

For an experiment to be successful and you want to repeat the good results, it’s necessary that your cannabis has the same phenotype and has been sown and harvested under the best conditions.

This is the only way to extract a pure THC that can be used to prepare recipes or medicinal oils.

So, how did the THC extraction go for you? We’d be delighted to hear about your experience.😜

How to extract CBD oil in your home kitchen

Non-psychoactive and increasingly popular as a relaxation drug, CBD can also be a DIY extract

By Sandra Hinchliffe

Excerpted with permission from CBD Every Day: How to Make Cannabis-Infused Massage Oils, Bath Bombs, Salves, Herbal Remedies, and Edibles by Sandra Hinchliffe. Copyright 2019 by Skyhorse Publishing, Inc.

Cannabidiol (CBD), an extract that many use as an anti-anxiety or relaxation tool, comes from the Cannabis sativa plant and cannot be divorced from this original source. Cannabis sativa has many different variations, and not all of these contain significant amounts of CBD. Prior to the gradual ending of cannabis prohibition in many locales, CBD was practically eliminated from the commercial black market to maximize profitability of the psychoactive cannabinoid content of the plants through selective breeding, according to many of the black-market growers I have spoken with throughout the years. The reason CBD is now widely accessible is most assuredly due to the change in social perceptions of this once-outlawed plant and the legalization of this plant in many locales. Without cannabis legalization, CBD would be difficult to acquire—and there would be no testing to ensure that consumers receive the product they are paying for.

In the process of developing recipes, I spent much of my time talking to CBD farmers and exploring their lush farms. I am forever grateful to my friends at Feather Canyon Farms in Del Norte County, California, for introducing me to some of the most impressive plants I’ve ever seen in my life. Beforehand, my experience with these plants had been limited to small indoor grows and the product offerings of our legal cannabis dispensaries.

One of the things I learned from the CBD farmers is that CBD can be an unstable and fleeting trait in cannabis plants. CBD production doesn’t just depend on the genetics of a plant, but the methods of growing, and what is also recognized in grape and wine production as the terroir. New strains of CBD-rich cannabis are being developed for the legal market all the time. I haven’t been able to try them all, but I’ve had the privilege of trying some of the most well-known strains, such as Harlequin, Harle-Tsu, ACDC, Cannatonic, Charlotte’s Web, Sour Tsunami, and a rare crop of Golden Goat, which expressed more than 8% CBD. This list is by no means complete in terms of CBD-rich cannabis strains available.

Hemp, the low-to-no THC variety of Cannabis sativa grown for the oilseed and fiber it produces, can also produce CBD in varying amounts. Both wild hemp and cultivated hemp can produce CBD in their resins. No matter what variety of Cannabis sativa produces CBD, the molecule is always the same.

Farmers, Plants, and Test Results over Brands: How To Select CBD Products

I believe that quality, whole-plant infusions and extractions matter. Epidiolex, the FDA-approved drug, is a whole-plant extract of CBD, purified, standardized, and manufactured for consistency. It’s rare as far as pharmaceuticals go; GW Pharma grows and processes their own cannabis to make therapeutic pharmaceuticals. Whether you are in need of a pharmaceutical treatment or are using CBD as a home remedy or for pleasure, you should be using whole-plant infusions and extractions. The cannabis farmers I spoke with have expressed a similar belief.

I am often asked about which brands of CBD are the best and which products to choose. But the truth is that when it comes to CBD, brands do not matter. Farms and plants matter. Selecting quality CBD-rich cannabis plant products begins with the farm they are grown on. Before you purchase any CBD product, know the farm and farmer. This is an easy task in most of our state-legal cannabis dispensaries, as this information will be readily available and even used as a marketing tool. This information is harder to find if you are purchasing CBD products from the over-the-counter herbal supplement market.

CBD products sold over the counter in the mainstream herbal supplement market do not have the oversight and regulated testing that most of our state-legal dispensary systems have. If you choose to purchase CBD products in the herbal supplement market, you must rely on the information they provide to you in terms of acquisition of plant material and test results. You must also be aware that there is controversy (both legal and scientific) surrounding the purchase of CBD products over the counter through the mainstream herbal supplement marketplace.

Test results matter. The herbal supplement marketplace is largely unregulated and a bit like the Wild West. An exposé in the New York Times in 2013 detailed some very disturbing problems with the herbal supplement marketplace and the fact that consumers often do not receive the products they are paying for. As well, CBD supplement merchants in the over-the-counter herbal supplement market have been cited by the FDA for many violations around the labeling and distribution of their products.

Certainly, I am not saying that all herbal supplement products are bad. What I am saying is that it is a wise decision as a consumer to seek out information and verify it if you are purchasing supplement products of any kind. And you should also be aware that not all locales will regard the purchase of CBD products as a legal activity.

The functionality of this book is to show you how to seek, find, and enjoy CBD-rich cannabis. Facts and aesthetics both matter if what you seek is a quality product and a satisfying experience.

In the recipes that follow, the focus is on whole-plant CBD-rich cannabis extractions and infusions, as these high-quality, artisanal, and farmer-centric whole plants and whole-plant resins will unfold themselves with fragrant and delicious complexity in your kitchen. My wish is for you to enjoy and benefit from everything CBD-rich cannabis offers without missing anything.

CBD to THC Ratio Selection and Dosing

Selection and dosage amount of CBD or CBD: THC is a very individual process and an ideal dosage that works as a one-size-fits-all amount does not exist. If you have concerns about what is best for you, this is something you should discuss with your personal physician. There are also MDs and DOs who specialize in cannabis therapeutics who can guide you based on your current health situation. If you are considering CBD for therapeutic medicinal purposes, it’s a good idea to consult with a physician who has knowledge and experience in this area before you begin.

I’ve developed a checklist that you can use and that I hope will guide you to the products that are worthy of your consideration:

— Is the name of the farm or farmer disclosed on the product label or available from the company or merchant selling the product?

— Does the product have test results from a third-party lab independent of any brand or manufacturer? Can you verify these results independent of a company, merchant, or legal dispensary?

— Do the test results include more than just CBD and other cannabinoid content?

— Are there test results for pesticides, mold, and other contamination? (Cannabis is a powerful soil remediator and easily absorbs toxic chemicals from the soil it is grown in.)

— If the product you would like to purchase is raw plant material, have you scoped it to check for mold or insects? Most dispensaries have magnification scopes for their customers to use—take advantage of this.

— Does the product look fresh, and does it smell fresh and clean? Is the product or plant material dated with harvest time or an expiration date?

CBD Farmer’s Oil Recipe with Whole Flowers

When one considers flavors, textures, freshness, effects, and fragrances as the starting point of evaluating a quality CBD oil product, this recipe will produce a gourmet oil extraction that will impress even the most experienced connoisseur.

Farmers know best. And this oil recipe was given to me by one of the most hardworking and knowledgeable CBD farmers I have met, Mr. Jesse Davis of Feather Canyon Farms in Del Norte County, California.

I experienced many pleasant surprises while sampling this oil at home, and the process of making it was even more surprising. Rich in both CBD and the natural terpenes of the Harle-Tsu CBD-rich cannabis plant, this oil is a gorgeous emerald color with a sublime minty and herbaceous flavor that I have never experienced with a CBD oil previously. This oil was completely non-intoxicating, but it was very pleasant and relaxing.

This oil, processed in MCT oil (fractionated coconut oil) at a low temperature for 24 hours, produced a CBD oil product that has lab tested at 10mg CBD and less than 1 mg

THC per 1ml dose. How low was that temperature? 175°F (80°C)—a temperature much lower than what is typically expected for a complete decarboxylation. What made the difference? The slow processing of this oil over a 24-hour period. Decarboxylation takes place with temperature, time, or in this case, both time and temperature.

I am satisfied that the flavor profile of this oil was only possible due to the careful, low-temperature processing technique that retained the majority of naturally occurring terpenes in the whole cannabis flowers from the CBD-rich Harle-Tsu cannabis strain grown in the mountain region of Del Norte County. Flower quality really does matter when it comes to producing an exquisite CBD oil such as this one.

This makes approximately 10 oz. (296ml) of CBD oil, but you can increase or decrease the amount of oil or flowers depending on the CBD concentration you desire.

10 oz. (296ml) MCT oil or more (otherwise known as liquid fractionated coconut oil)

1 oz. (28g) or more whole CBD-rich, low-or-no- THC cannabis flowers, cured, dried, and chopped

  1. This recipe requires a slow cooker with a low heat setting to process this oil correctly. Add the chopped cannabis to the slow cooker.
  2. Pour the oil over the cannabis, making sure that all the flower material is covered. If you need to add a little extra oil to cover the flowers, you should do so at this time. Cover the slow cooker and set to the low or low cook setting (depending on your model).
  3. Within at least 3 hours, your slow cooker should reach the final processing temperature of about 175°F (80°C). Use a candy thermometer to verify the temperature and adjust if necessary. Stir the oil and plant material at this time and cover the slow cooker once again.
  4. Every few hours, stir the oil and flower material to evenly distribute the infusion throughout the process. Do not stir frequently, as this will allow more of the volatile terpenes to escape into the air. To preserve as many of the volatile constituents as possible, such as terpenes, leave the lid on the pot throughout the entire process. This can be left to process overnight without stirring.
  5. After the 24-hour period is over, cool the oil by unplugging the slow cooker and allowing the materials to remain in the pot and the oil to cool to room temperature a few more hours.
  6. Strain the oil from the plant material through cheesecloth and into a clean glass jar. The oil is now ready to use by itself in measured doses or in any recipe.

Store in a cool, dark, and dry area. Use within 6 months for freshest flavor
