## The Short Answer
A cannabis tincture is a liquid cannabis extract, typically in an alcohol, MCT-oil, or glycerin base, taken under the tongue (sublingually) for faster onset than edibles and more predictable dosing than inhalation. For adults 21 and older, tinctures are one of the simplest products to dose accurately, which is why they're often recommended as a starting point for consumers new to cannabis.
## How Tinctures Work
Tinctures deliver cannabinoids through the mucous membranes under the tongue, which puts them into the bloodstream faster than digestion does. Sublingual onset is typically 15 to 45 minutes, slower than smoking or vaping (seconds), but much faster than edibles (30 to 120 minutes). Duration sits in the middle of the range too: 3 to 6 hours for most tinctures, depending on dose and individual response.
If you swallow a tincture instead of holding it under the tongue, it behaves more like an edible, slower onset, longer duration. Some consumers do both deliberately; most hold sublingually for 60 to 90 seconds and then swallow.
## Reading a Tincture Label
The key number on a tincture bottle is **milligrams of THC per milliliter (mL)**. Common ratios:
- **10 mg THC per mL** in a 30 mL bottle = 300 mg total per bottle.
- **5 mg THC per mL** in a 30 mL bottle = 150 mg total.
- **1:1 THC:CBD** products list both cannabinoids separately.
The dropper is usually marked in 0.25 mL, 0.5 mL, and 1 mL increments, which makes milligram-math straightforward. A half-dropper of a 10 mg/mL tincture is 5 mg THC.
## Dosing for Beginners
For an adult 21+ who has never used cannabis before, 2 to 5 mg THC is a reasonable starting dose. Wait the full onset window (45 to 60 minutes) before taking more. The universal rule applies: **start low, go slow**. See [start low and go slow, the golden rule of cannabis dosing](/blog/start-low-and-go-slow-the-golden-rule-of-cannabis-dosing).
## CBD Tinctures and Ratios
Many tinctures are formulated as THC:CBD ratios — 1:1, 2:1, 1:3, 1:20, and similar. The reasoning: higher-CBD tinctures often produce milder intoxication and are used by consumers looking for a subtle experience. These are marketed for a reason, not because they "treat" anything; no medical claims follow from the ratio alone.
## Using Them
A few consumer notes:
- **Shake before use.** Settled cannabinoids concentrate at the top or bottom of the bottle depending on the base.
- **Alcohol-based tinctures** taste sharp but absorb faster. MCT-oil-based tinctures are milder but slower.
- **Store away from light and heat.** Cannabinoids degrade; a dark cabinet is fine.
- **Track your doses** for the first week. Knowing what 5 mg feels like for you is more useful than anyone else's review.
