Cannabis Tinctures Guide: Alcohol-Based Extraction Methods

Cannabis tinctures offer a smoke-free, precise way to consume cannabis. These alcohol-based extracts absorb quickly when taken under the tongue and can be added to foods and drinks.

Quick Answer

Cannabis tinctures are made by soaking decarboxylated cannabis in high-proof alcohol (Everclear) for 2-6 weeks, then straining. Tinctures taken sublingually (under tongue) work in 15-30 minutes. They are precise to dose and have a long shelf life.

What is a Cannabis Tincture?

A tincture is a liquid cannabis extract made using alcohol as the solvent. Unlike oil-based infusions, tinctures can be absorbed directly through mouth tissues for faster onset.

Advantages of Tinctures

Fast-acting: Sublingual absorption bypasses digestion, taking effect in 15-30 minutes.

Precise dosing: Dropper allows exact measurement, typically 1ml at a time.

Long shelf life: Alcohol preserves tinctures for years when stored properly.

Versatile: Take directly, add to food/drinks, or use in recipes.

Discreet: Small bottles are portable with no cannabis odor.

No calories: Unlike butter or oil infusions.

What You Need

Ingredients

7-14 grams decarboxylated cannabis
1-2 cups high-proof alcohol (Everclear 190-proof preferred)

Choosing Your Alcohol

Best choice: Everclear 190-proof (95% alcohol)

Highest extraction efficiency
Evaporates completely
Available in most states

Alternative: Everclear 151-proof (75.5% alcohol)

Available where 190-proof is restricted
Still effective, slightly lower efficiency

Avoid: Vodka, rum, or spirits under 100 proof

Too much water content
Lower extraction efficiency
Taste may affect final product

Equipment

Mason jar with lid
Fine mesh strainer or cheesecloth
Dark glass dropper bottles (amber or cobalt)
Funnel
Measuring cup

Traditional Cold Extraction Method

Step 1: Decarboxylate Cannabis

Bake cannabis at 240°F for 40-60 minutes. This activates THC - do not skip this step.

Step 2: Combine in Mason Jar

Place decarbed cannabis in mason jar. Pour enough alcohol to cover cannabis by 1 inch.

Ratio: 1 cup alcohol per 7g cannabis is a good starting point.

Step 3: Seal and Store

Seal jar tightly. Store in cool, dark location.

Step 4: Shake Daily

Shake jar vigorously once daily. This improves extraction.

Step 5: Wait 2-6 Weeks

Minimum: 2 weeks Optimal: 4-6 weeks Maximum benefit: 8 weeks

Longer soaking extracts more cannabinoids and terpenes.

Step 6: Strain

Pour through cheesecloth or fine mesh strainer into clean container. Squeeze gently to extract all liquid.

Step 7: Bottle and Store

Transfer to dark glass dropper bottles using funnel. Label with date and estimated potency.

Quick Wash Method (QWET)

For faster results with less chlorophyll extraction:

Process

Freeze both cannabis and alcohol overnight (minimum 24 hours)
Combine frozen cannabis and alcohol in mason jar
Shake vigorously for 3 minutes only
Strain immediately through coffee filter
Repeat with fresh alcohol if desired for second wash

Why Freezing Helps

Cold temperatures prevent chlorophyll from dissolving in alcohol, resulting in cleaner, less bitter tincture.

Trade-off: Less extraction time means slightly lower potency than traditional method.

Using Cannabis Tinctures

Sublingual Method (Fastest)

Draw desired dose in dropper
Place drops under tongue
Hold for 60-90 seconds
Swallow remaining liquid

Onset: 15-30 minutes Duration: 2-4 hours

Adding to Food/Drinks

Add tincture to any food or beverage. Alcohol evaporates when heated.

Note: When swallowed directly (not sublingual), effects take longer (30-90 minutes) as tincture is processed through digestion.

Recipes

Add to coffee, tea, or cocktails
Mix into salad dressings
Drizzle over desserts
Blend into smoothies

Dosing Tinctures

Calculating Potency

Example with 10g cannabis at 20% THC:

Total THC: 10 x 0.20 x 1000 = 2,000 mg
After extraction (~90% efficiency): 1,800 mg THC total
In 2 cups (480ml) alcohol: 3.75 mg per ml

Standard Dropper

Most droppers dispense approximately 1ml per full dropper (about 30 drops).

Recommended Starting Doses

Beginners: 0.25ml (about 7 drops or 1/4 dropper)
Regular users: 0.5-1ml (15-30 drops)
Experienced: 1-2ml (1-2 full droppers)

Reducing Alcohol Burn

High-proof alcohol can burn under the tongue. To reduce this:

Evaporation Method

Leave tincture in open shallow dish for 24-48 hours. Alcohol evaporates, concentrating cannabinoids and reducing burn.

Caution: Do this in well-ventilated area away from flames. Alcohol is flammable.

Glycerin Transfer

After making alcohol tincture, evaporate most alcohol, then mix with food-grade vegetable glycerin. Glycerin is sweet and less harsh.

Storage and Shelf Life

Optimal Storage

Dark glass bottle (amber or cobalt)
Cool, dark location (refrigerator works well)
Away from children and pets

Shelf Life

Properly stored tinctures last 3-5 years or longer. Alcohol preserves cannabinoids effectively.

Signs of Degradation

Color change (may darken over time - normal)
Sediment formation (normal, shake before use)
Off smell (rare with alcohol-based tinctures)

Troubleshooting

Tincture is very bitter

Too much plant material extracted
Try quick wash method next time
Add honey or sugar when consuming

Tincture seems weak

Did not decarboxylate properly
Used low-proof alcohol
Did not soak long enough
Cannabis was lower potency than expected

Too much alcohol burn

Use evaporation method to reduce alcohol
Mix with beverage before consuming
Switch to glycerin tincture

Tinctures vs Other Consumption Methods

Method	Onset	Duration	Precision	Discretion
Tincture (sublingual)	15-30 min	2-4 hrs	High	High
Edible	30-120 min	4-8 hrs	Medium	High
Smoking	5-10 min	1-3 hrs	Low	Low
Vaping	5-10 min	1-3 hrs	Medium	Medium

Cannabis tinctures combine fast onset with precise dosing, making them ideal for medicinal users and anyone seeking controlled cannabis experiences.
