Getting dosing right starts with clear definitions and patient tracking. This guide explains THC vs. CBD, common ratios (e.g., 1:1, 2:1, 20:1), and typical onset/duration across product types.

THC, CBD, and Ratios
- THC: psychoactive; contributes to euphoria and impairment at higher doses.
- CBD: non-intoxicating; may modulate some THC effects.
- Ratios describe THC:CBD. Examples:
- 1:1 \u2192 roughly balanced THC and CBD
- 2:1 \u2192 THC-leaning (twice as much THC as CBD)
- 10:1 or 20:1 \u2192 CBD-leaning
Tip: Labels may show mg per unit (e.g., per gummy) or mg/mL for tinctures. See our Cannabis Glossary.
Onset & Duration (Typical Ranges)
- Inhaled (vape/flower): onset minutes, duration 2–4 h.
- Sublingual tinctures: onset ~15–60 min, duration 3–6 h.
- Edibles: onset ~30–120 min, duration 6–8+ h.
- Topicals (non-transdermal): local effects only; onset ~15–60 min, duration varies.
These are general patterns; individual responses differ. See Responsible Use for impairment guidance.
Start Low, Go Slow (Titration Steps)
- Pick a format with clear labeling (e.g., tincture or low-dose edible).
- First dose: choose very small amounts and wait for full onset before considering more.
- Increase gradually over days, tracking dose, time, and effects in a simple log.
- Aim for the minimum effective dose. If side effects appear, step back.
For detailed safety and update cadence, see Responsible Use and Research Updates.
Choosing a Ratio
- Cautious or daytime use: consider CBD-leaning ratios (e.g., 10:1, 20:1).
- Balanced effects: 1:1 may feel more even for some.
- THC-leaning: experienced users may prefer 2:1 or higher THC.
Always check labeling and any Certificate of Analysis when available; see How We Review Products.
Interactions & Health Considerations
If you take prescription meds or have cardiovascular, liver, or balance conditions, consult a clinician. Laws vary by location—check Cannabis Laws.
