¶ Tinctures & Sublingual
Cannabis tinctures are liquid extracts of cannabis dissolved in a carrier liquid -- typically alcohol, glycerin, or oil -- that are administered sublingually (under the tongue) or swallowed. Sublingual administration allows cannabinoids to be absorbed directly through the mucous membranes of the mouth into the bloodstream, producing effects faster than edibles while avoiding the respiratory exposure of inhalation methods.
Tinctures are one of the oldest forms of cannabis medicine, having been a standard item in Western pharmacopeias throughout the 19th century before cannabis prohibition. Today, they are experiencing a renaissance as a precise, discrete, and medically appropriate consumption method.
¶ What Are Tinctures?
A tincture is a concentrated liquid extract made by dissolving the active compounds of a plant material in a solvent. Cannabis tinctures are produced by:
- Decarboxylating cannabis material to activate cannabinoids (see Edibles for decarboxylation)
- Soaking the decarboxylated material in a solvent (alcohol, glycerin, or oil) for an extended period
- Agitating periodically to encourage dissolution
- Straining out the plant material, leaving a cannabinoid-rich liquid
The resulting tincture is typically packaged in small glass bottles with calibrated droppers for precise dosing.
¶ Sublingual Absorption
Sublingual administration is the primary method for consuming cannabis tinctures. Here is how it works:
¶ The Absorption Pathway
- Tincture is placed under the tongue -- The area under the tongue (sublingual mucosa) is rich in blood vessels and has a thin epithelial layer
- Cannabinoids diffuse through the mucous membrane -- The alcohol or oil carrier helps cannabinoids cross the membrane
- Direct entry into bloodstream -- Absorbed cannabinoids enter the sublingual veins and travel directly to systemic circulation, bypassing the digestive system and liver
- Effects begin -- Typically within 15-45 minutes
¶ Sublingual vs. Swallowed
| Route | Absorption Pathway | Onset | Duration | Bioavailability |
|---|---|---|---|---|
| Sublingual (held under tongue) | Through oral mucosa into bloodstream | 15-45 minutes | 4-6 hours | ~15-35% |
| Swallowed (ingested like an edible) | Through digestive system and liver | 30-90 minutes | 4-8 hours | ~10-20% |
| Combined (hold, then swallow) | Both sublingual and digestive | 15-45 min (initial) + 30-90 min (secondary) | 4-8 hours | ~15-35% |
💡 For the fastest onset and most efficient absorption, hold the tincture under your tongue for 60-90 seconds before swallowing. This maximizes sublingual absorption while any remaining product is then processed through the digestive system.
¶ Key Metrics
| Metric | Sublingual | Swallowed (Edible-like) |
|---|---|---|
| Onset time | 15-45 minutes | 30-90 minutes |
| Duration | 4-6 hours | 4-8 hours |
| Bioavailability | ~15-35% | ~10-20% |
| Peak effects | 45-90 minutes | 2-3 hours |
¶ Dosing with Droppers
¶ Understanding Tincture Potency
Tincture potency is typically labeled as total milligrams of cannabinoids per bottle or per milliliter:
| Labeling | Example | Meaning |
|---|---|---|
| Total mg per bottle | "500mg THC in 30ml bottle" | The entire bottle contains 500mg THC; each ml contains approximately 16.7mg |
| mg per ml | "10mg THC per ml" | Each milliliter of tincture contains 10mg THC |
| mg per drop | "0.5mg THC per drop" | Each drop from the dropper contains 0.5mg THC |
¶ Dropper Volume Reference
| Measurement | Approximate Volume | Approximate Drops |
|---|---|---|
| Full dropper (1ml standard) | 1.0 ml | 20-30 drops (varies by dropper and liquid viscosity) |
| Half dropper | 0.5 ml | 10-15 drops |
| Quarter dropper | 0.25 ml | 5-8 drops |
| Single drop | ~0.03-0.05 ml | 1 drop |
⚠️ Warning Droppers are not perfectly calibrated across manufacturers. Always check the product label for specific mg/ml information and use the provided dropper. When in doubt, start with a fraction of a dropper and wait for effects before consuming more.
¶ Recommended Starting Doses
| Experience Level | Starting Dose (THC) | Approximate Volume (at 10mg/ml) |
|---|---|---|
| Beginner | 1-2.5 mg | 0.1-0.25 ml (2-5 drops) |
| Moderate | 2.5-5 mg | 0.25-0.5 ml (5-10 drops) |
| Experienced | 5-15 mg | 0.5-1.5 ml |
| Medical (as directed) | Varies per physician guidance | Varies |
¶ How to Use a Tincture
¶ Step-by-Step Sublingual Administration
Step 1: Shake the bottle
Cannabinoids and carrier oils may separate over time. Shake gently to ensure even distribution.
Step 2: Measure the dose
Use the dropper to draw up the desired amount. Check the measurement markings on the dropper.
Step 3: Place under the tongue
Squeeze the dropper to release the tincture under your tongue.
Step 4: Hold for 60-90 seconds
Keep the tincture under your tongue for at least 60-90 seconds. Avoid swallowing during this time.
Step 5: Swallow
After holding, swallow the remaining liquid. Any cannabinoids not absorbed sublingually will be processed through the digestive system.
Step 6: Wait
Wait at least 45-60 minutes before evaluating effects and considering additional dosing.

| Long shelf life -- Especially alcohol-based tinctures | Alcohol-based tinctures can last years when stored properly |
| Good for medical patients | Precise dosing, easy to administer, no preparation required |
| Flexible administration | Can be taken sublingually, swallowed, or added to food/drink |
| Ratio products available | THC:CBD ratios allow tailored therapeutic effects |
¶ Disadvantages and Limitations
| Disadvantage | Description |
|---|---|
| Taste | Cannabis tinctures have a distinct, often bitter taste (can be masked with flavored products) |
| Slower than smoking/vaping | 15-45 minutes vs. 1-5 minutes for inhalation |
| Alcohol base may irritate | Some people find alcohol-based tinctures irritating to the mouth |
| Dosing learning curve | Beginners may need several sessions to find their ideal dose |
| Cost | Commercial tinctures can be expensive per mg compared to flower |
¶ Types of Tinctures
¶ By Carrier Liquid
| Type | Carrier | Characteristics |

¶ How to Make Tincture at Home
ℹ️ Info
The following is provided for educational purposes. Always comply with applicable laws regarding cannabis possession and processing.
¶ Green Dragon (Alcohol-Based Tincture)
Materials needed:
- Decarboxylated cannabis flower (7-14 grams)
- High-proof food-grade ethanol (190-proof / 95% ethanol preferred) -- enough to fully submerge the material
- Glass jar with airtight lid
- Coffee filters or fine mesh strainer
- Dark glass dropper bottles for storage
Step 1: Decarboxylate
Decarboxylate your cannabis at 220-240 degrees F (104-116 degrees C) for 30-45 minutes. See Edibles for detailed instructions.
Step 2: Combine
Place the decarboxylated cannabis in a glass jar and cover completely with ethanol. Use enough ethanol to submerge the material with approximately 1-2 inches of liquid above it.
Step 3: Soak and Agitate
Seal the jar and store in a cool, dark place. Agitate (shake) the jar once or twice daily. Soaking time ranges from:
- Quick soak: 24-48 hours (lighter, less chlorophyll)
- Standard soak: 1-2 weeks (balanced)
- Long soak: 4-6 weeks (strongest, more chlorophyll)
Step 4: Strain
Strain the liquid through coffee filters or a fine mesh strainer into a clean container. Squeeze the plant material to extract as much liquid as possible.
Step 5: Bottle
Transfer the strained liquid into dark glass dropper bottles. Label with the date, estimated potency, and cannabinoid ratio.
Step 6: Store
Store in a cool, dark place. Alcohol-based tinctures have an extended shelf life of 2-5 years.
¶ Oil-Based Tincture (Simpler, Milder)
Materials needed:
- Decarboxylated cannabis
- MCT oil, olive oil, or other carrier oil
- Double boiler or saucepan
- Cheesecloth or fine strainer
- Dark glass dropper bottles
Process:
- Combine decarboxylated cannabis with oil in a double boiler
- Heat on low (160-200 degrees F / 71-93 degrees C) for 2-4 hours
- Strain through cheesecloth
- Bottle in dark glass dropper bottles
- Store in a cool place or refrigerate (oil-based tinctures have shorter shelf life)
