Cannabis tinctures are genuinely one of the most underrated forms of consumption, and if you have not explored them yet, you are missing out. They are discreet, fast-acting when used sublingually, easy to dose accurately, and remarkably simple to make at home. They also last a very long time when stored correctly, which is more than you can say for most homemade cannabis products.
If you have ever wanted something that does not require smoking, does not take two hours to hit like a space brownie, and fits neatly into your daily routine, cannabis tinctures might be exactly what you have been looking for.
What Is a Cannabis Tincture?
A cannabis tincture is a liquid extract of cannabis, typically made using high-proof alcohol (the most common and most effective method) or food-grade vegetable glycerin as the solvent. The solvent pulls cannabinoids and terpenes from the plant material, resulting in a concentrated liquid that you can dose precisely with a dropper.
Tinctures are consumed sublingually (under the tongue) for the fastest onset, typically 15 to 45 minutes, or added to food and beverages where they behave more like edibles with a 1 to 2 hour onset. Either way, they are a clean, controlled way to consume cannabis.
Before you start, you need to understand one foundational step: decarboxylation. Raw cannabis contains THCA, not THC. Without heating your cannabis first to activate its cannabinoids, your tincture will be full of inactive compounds. Do not skip this step.
What You Need
For alcohol tincture:
- Cannabis flower (3.5 to 7 grams for a small batch)
- High-proof food-grade alcohol (Everclear 190-proof is ideal; 151-proof works; do not use isopropyl alcohol)
- Glass jar with tight-fitting lid (Mason jar works perfectly)
- Fine mesh strainer or cheesecloth
- Glass dropper bottles for storage
- Funnel (helpful but not essential)
For glycerin tincture (alcohol-free option):
- Same as above but substitute vegetable glycerin for the alcohol
- Note: glycerin is a less efficient solvent than alcohol, so glycerin tinctures tend to be less potent and have a slightly sweet taste
Step 1: Decarboxylate Your Cannabis
Preheat your oven to 225 to 240°F (107 to 115°C). Break your cannabis into small pieces, spread it on a parchment-lined baking sheet, and bake for 30 to 45 minutes. The cannabis should look slightly toasted and smell earthy. Let it cool completely before proceeding.
If you have already read our full decarboxylation guide, you know the details. If not, go read it. It matters.
Step 2: Combine Cannabis and Alcohol
Place your decarbed cannabis in the glass jar. Pour enough alcohol to completely cover the cannabis, plus about an inch above the material. For 3.5 grams of flower, roughly 2 to 4 ounces (60 to 120ml) of alcohol is a reasonable starting point.
The ratio affects potency. More alcohol per gram of cannabis means a more dilute tincture. Less alcohol per gram means more concentrated drops. There is no single right answer; it depends on your intended dose per dropper and your preference for tincture strength.
Step 3: Choose Your Extraction Method
There are two main approaches:
The Quick Wash Method (QWET)
This is the fastest method and produces a clean, high-quality tincture. Place your cannabis and alcohol in the jar and shake vigorously for 1 to 3 minutes. Do not soak. Immediately strain and bottle.
The logic: a quick, aggressive wash pulls cannabinoids and terpenes efficiently without extracting excessive chlorophyll and plant material, which causes the harsh, green bitterness that makes some tinctures unpleasant.
For the absolute cleanest quick wash, chill both your cannabis and your alcohol in the freezer for a few hours before combining. Cold temperature slows chlorophyll extraction while still allowing cannabinoid extraction. The result is a lighter-colored, smoother tincture.
The Long Soak Method
Place cannabis and alcohol in the jar, seal tightly, and store in a cool, dark place for 2 to 8 weeks, shaking the jar daily. Longer soaks extract more total material but also pull more plant matter and chlorophyll.
Long-soak tinctures tend to be darker and more herbaceous in flavor. Some people prefer this earthy character; others find it overwhelming. The potency ceiling is similar to the quick wash method; the main difference is flavor profile and how much plant material ends up in your final product.
Step 4: Strain and Bottle
- Set your strainer or cheesecloth over a clean glass bowl or measuring cup
- Pour the cannabis-alcohol mixture through, letting gravity do the work
- Gently press the plant material to extract remaining liquid, but do not squeeze hard or you will push more plant matter through
- Using a funnel, transfer the strained tincture into your dropper bottles
- Label each bottle with the cannabis used, date made, and approximate potency if you know it
Estimating Potency
This is where most home producers get vague, and it does not have to be. Here is a rough calculation:
If your cannabis is labeled at 20% THC and you used 3.5 grams (3,500mg), then:
- 3,500mg × 0.20 = 700mg total THC in your batch
- If you ended up with 4 ounces (120ml) of tincture, that is roughly 5.8mg THC per ml
- A standard dropper holds about 1ml, so each full dropper delivers approximately 5 to 6mg THC
This is an estimate, not a certified lab result. Home tinctures vary in potency depending on decarb efficiency, extraction time, and strain variability. Start with half a dropper and wait an hour before deciding if you need more.
How to Use Cannabis Tincture
Sublingual (Under the Tongue)
Drop your dose under the tongue and hold it there for 60 to 90 seconds before swallowing. The mucous membranes absorb cannabinoids directly into the bloodstream, bypassing the digestive system. Onset is typically 15 to 45 minutes, faster than edibles and more controlled than smoking.
Added to Food or Drink
Add your dose to juice, a smoothie, salad dressing, or any food where the alcohol taste blends in. This method works more like a traditional edible, with a longer onset of 1 to 2 hours, so patience is required.
Note that adding alcohol-based tincture to hot drinks causes the alcohol to evaporate, which may slightly reduce potency and will definitely change the flavor profile.
Glycerin Tinctures: The Alcohol-Free Alternative
For those who avoid alcohol entirely, vegetable glycerin tinctures are a valid option. The process is the same, but glycerin is a far less efficient solvent. You will typically need a longer extraction time (2 to 4 weeks minimum) and the resulting tincture will be less potent than an equivalent alcohol version.
Glycerin tinctures have a naturally sweet taste that many users prefer. They are also gentler on mucous membranes for those who find alcohol irritating under the tongue.
Storage and Shelf Life
Properly stored alcohol tinctures last years. High-proof alcohol is an excellent preservative. Keep your bottles in a cool, dark place (a cabinet or drawer works perfectly) and away from heat sources.
Glycerin tinctures have a shorter shelf life of roughly one to two years. Both types should be checked periodically for changes in color, smell, or consistency that might indicate degradation.

Common Mistakes to Avoid
- Skipping decarboxylation: Your tincture will be almost entirely inactive. This is the single biggest mistake home tincture makers make.
- Using rubbing alcohol (isopropyl): Never. This is not food-grade and is not safe for consumption. Use drinking-grade high-proof spirits only.
- Overdosing early: Tinctures are potent and the alcohol extraction is efficient. Always start with a low dose.
- Long soaking without cold temps: Warm or room-temperature long soaks pull a lot of chlorophyll. Keep it cold or go quick wash.
- Glass containers only: Alcohol can leach compounds from plastic over time. Always use glass for storage and preparation.
Cannabis tinctures represent some of the cleanest, most controllable home consumption you can make yourself. Once you have the process down, you will wonder why you ever bought pre-made options at the dispensary at those prices. Your pantry can do better.
