When it comes to THC extraction using alcohol, the type of alcohol and its proof are crucial factors. The most commonly used alcohols for this process are ethanol and isopropyl alcohol. Ethanol, also known as drinking alcohol, is safe for human consumption and effective in extracting cannabinoids from cannabis plants. Isopropyl alcohol, on the other hand, is considered toxic and often avoided by the cannabis community. To ensure a successful extraction, high-proof ethanol is recommended, typically 190 proof (95% ABV) or 200 proof (100% ABV). Lower-proof alcohol, such as 80 proof vodka, may not be as effective due to its weaker solvent capabilities and higher water content. The extraction process involves soaking cannabis in high-proof ethanol, which acts as a solvent to separate and extract the desired cannabinoids. This results in a concentrated solution that can be consumed orally or used in various cannabis-based products. It is important to prioritize safety during the extraction process due to the flammability of alcohol, especially when working with high-proof varieties.

The higher the alcohol proof, the greater the THC extraction capacity
When it comes to THC extraction using alcohol, the general rule is that the higher the alcohol proof, the greater the extraction capacity. This is because high-percentage alcohol is used as a solvent to extract the medicinal compounds (cannabinoids and terpenes) from the cannabis plant. The proof of commercial alcohol indicates the percentage of ethanol it contains; the proof is twice the percentage, so 80 proof means the mixture contains 40% ethanol.
For cannabis extraction, 190 proof or stronger (95-100% ethanol) is ideal. A higher alcohol content leads to better extraction. For instance, a 150 proof drink can theoretically absorb 50% more THC than a 100 proof drink. However, it is important to note that pure ethanol becomes poisonous at 200 proof due to the use of benzene to remove water. As such, many opt for Everclear, a 190 proof or 95% ethanol alcohol that is safe for oral consumption and acts as a strong natural solvent for THC extraction. It is also odourless and tasteless. If Everclear is unavailable, 151 proof rum or vodka can be used, although these are weaker solvents with higher water content, which can interfere with the extraction process.
The process of THC alcohol extraction involves three basic steps: washing the cannabis in alcohol, filtering out the plant matter, and evaporating the alcohol. This can be done through cold extraction, where cannabis is soaked in alcohol at room temperature for weeks, or warm extraction, where cannabis is heated to produce a full-spectrum product. Cold extraction at very low temperatures helps reduce the amount of undesirable compounds in the tincture, such as lipids and chlorophyll, while warm extraction will solubilize these compounds.
Safety is a critical consideration when performing alcohol extraction due to the high flammability of alcohol, especially high-proof alcohol. It should be performed in a well-ventilated area, and never boiled or evaporated indoors or near an open flame or spark. It is also important to ensure that no residual alcohol remains in the final product, as this can be dangerous for health and a fire hazard.

Ethanol is the safest alcohol for THC extraction
Ethanol is considered a safe alcohol for THC extraction. It is commonly used as a solvent to strip cannabis material from their desired chemical compounds. It is also known as ethyl alcohol or grain alcohol, and it is a colorless and flammable liquid. Ethanol is used in various products such as gasoline, beauty products, solvents, paints, and food additives.
Ethanol is effective in extracting THC as cannabinoids are soluble in ethanol at a 1:1 ratio, meaning 1 gram of THC is soluble in 1 milliliter of ethanol. This process retains the aromatic compounds while rendering the plant matter expendable, thereby concentrating the potency of the cannabinoids. Ethanol is also a polar solvent, which means it can dissolve water-soluble molecules like chlorophyll.
Ethanol extraction is a simple, fast, and safe process that can be performed by individuals at home. It is considered one of the safest solvents for extractions as it requires minimal safety equipment compared to other methods. However, it is important to note that ethanol is highly flammable, so extraction should be done in a well-ventilated area away from open flames or sparks.
The use of ethanol for THC extraction has a long history, dating back to the American Pharmacopeia of 1851. It is also recognized by the FDA as generally safe for human consumption and is commonly used as a food additive. Additionally, ethanol extraction can be cost-effective for manufacturers due to its lower startup costs in equipment, labor, and throughput.
Overall, ethanol is a safe and effective alcohol for THC extraction, offering advantages in terms of simplicity, safety, and cost-effectiveness when compared to other extraction methods.

Isopropyl alcohol is toxic and should be avoided
When it comes to THC extraction, the choice of alcohol is an important consideration. While isopropyl alcohol can be used for this purpose, it is important to be aware of the potential risks associated with its toxicity.
Isopropyl alcohol, also known as isopropanol, is a clear, colorless, and flammable liquid with a pungent odor. It is commonly found in rubbing alcohol, hand sanitizers, and certain cleaning products. While it may be used for THC extraction, particularly in hash-making, it is important to exercise caution due to its toxic nature.
The toxicity of isopropyl alcohol can lead to serious health risks. Ingesting, inhaling, or even applying it to the skin can result in poisoning, especially in large amounts. Symptoms of poisoning include dizziness, headache, nausea, vomiting, abdominal pain, hypotension, hypothermia, respiratory depression, and even coma. It is worth noting that isopropyl alcohol is more toxic than ethanol, the type of alcohol commonly used in alcoholic beverages.
The health risks associated with isopropyl alcohol are significant. Even though death from ingestion is rare, it can cause severe central nervous system depression and cardiopulmonary collapse. The potential dangers of isopropyl alcohol poisoning highlight the importance of choosing alternative extraction methods or substances with lower toxicity.
When considering the use of isopropyl alcohol for THC extraction, it is crucial to prioritize safety. The potential health hazards associated with its toxicity cannot be overstated. As such, it is highly recommended to opt for alternative substances, such as ethanol, which is considered safe for human consumption and effective for THC extraction. By avoiding isopropyl alcohol and exercising caution, you can ensure a safer extraction process while still achieving the desired results.

Alcohol is highly flammable, so THC extraction should be done in a well-ventilated area
When extracting THC with alcohol, it is important to remember that ethanol and all other types of alcohol are highly flammable as liquids and vapors. Therefore, the process should be done in a well-ventilated area to ensure safety and avoid potential fires or health hazards.
THC extraction using alcohol can be done by DIYers using simplified methods, but it is not without potential dangers. Alcohol, especially high-proof alcohol, is highly flammable and should never be evaporated indoors or near an open flame or spark. It is crucial to take the proper safety precautions when performing THC extraction.
One common method for THC alcohol extraction is to use Everclear, a high-proof grain alcohol that serves as an excellent solvent for creating concentrates. If Everclear is unavailable, a safe alternative for oral consumption is 95% (190-proof) alcohol. The process involves breaking apart the nugs by hand, drying the cannabis in the oven, transferring it to a glass jar, and then soaking it in alcohol. The mixture is stirred gently, strained, and evaporated.
During the evaporation process, it is essential to ensure adequate ventilation. One approach is to place the mixture near an open window with a ventilation fan blowing towards the window to increase evaporation and direct fumes outside. This helps to reduce the risk of fire and maintain a safe working environment.
Additionally, it is worth noting that the potency of the alcoholic drink used in THC extraction impacts its capacity for extraction. Generally, the stronger the alcoholic drink, the greater its ability to extract THC. For example, a 150-proof drink can theoretically absorb 50% more THC than a 100-proof drink. However, the effect can also be influenced by other compounds present in the alcoholic beverage.

THC extraction with alcohol is a simple, fast, and safe process
There are various methods for THC extraction using alcohol. One common method involves using ethanol or isopropyl alcohol. The process is straightforward: freeze your plant material and alcohol separately, then place the plant material into the alcohol jar and shake. The longer you keep the jar in the freezer and the more you shake it, the more you extract. After extraction, filter the mixture through a coffee filter and let the alcohol evaporate under a fan.
If you want to make a tincture or oil for ingestion, excluding compounds like chlorophyll, waxes, and lipids is less important. However, if producing a high-purity extract for vaporization or smoking, it's best to keep these compounds out by performing the extraction at very low temperatures. THC dissolves faster at higher temperatures, but undesirable compounds may be extracted, impacting the final quality.
Some people also use a rotary evaporator and a vacuum pump to purge the alcohol from their extract. This equipment is expensive, so an alternative method is to freeze the extract and crush it into a powder, then sprinkle it over chilled buds.
