CBD & THC Dosage Guide: How Much Should I Take?
New to CBD or THC and not sure where to start? This guide walks you through how to find the right dose, how to read labels, and how to adjust your cannabinoids over time. We’ll cover CBD, THC, CBD:THC ratios, product types, and real-world dosing ranges so you can feel more confident when you shop and consume.
Important: This guide is for educational purposes only and does not replace medical advice. Always talk to your doctor or healthcare provider before using CBD or THC products, especially if you take medications, are pregnant, or breastfeeding.
Find Your Dose with RESTART CBDWhy CBD & THC Dosing Matters
Cannabinoids like CBD (cannabidiol) and THC (tetrahydrocannabinol) interact with your body’s endocannabinoid system, which helps regulate mood, sleep, comfort, appetite, and more. The right dose for one person may feel totally different for someone else.
Several factors impact your ideal dose:
- Body weight & metabolism – Higher body mass and faster metabolism can change how you respond.
- Experience & tolerance – New consumers often need much less than experienced users.
- Product type – Oils, gummies, vapes, and topicals all absorb differently.
- Cannabinoid profile – CBD, THC, and other minor cannabinoids (CBG, CBN, etc.) all play a role.
- Desired effect – Daily wellness support, nighttime relaxation, or more targeted comfort may require different ranges.
The golden rule is: start low and go slow. Begin with a low dose, pay attention to how you feel over several days, and increase gradually only if needed.
CBD Dosage Guide
CBD is non-intoxicating, meaning it doesn’t create the “high” associated with THC. Many people use CBD daily for general wellness, mood support, exercise recovery, or sleep support.
General CBD Dosing Ranges
These ranges are general guidelines and can vary from person to person. Always listen to your body and adjust slowly.
| Goal | Suggested Starting Dose | Common Daily Range |
|---|---|---|
| Everyday wellness / stress support | 5 – 10 mg CBD once daily | 10 – 40 mg CBD per day |
| Discomfort / exercise recovery | 10 – 20 mg CBD once or twice daily | 20 – 80+ mg CBD per day, divided doses |
| Sleep support | 20 – 30 mg CBD 1–2 hours before bed | 30 – 120+ mg CBD per evening (as tolerated) |
These ranges are for generally healthy adults. Your ideal amount may be lower or higher. Consult your healthcare provider for personalized guidance.
How to Calculate CBD mg per Dropper
To dose CBD oils or tinctures accurately, it helps to know how many milligrams (mg) of CBD are in each full dropper. Use this simple formula:
- Find the total mg per bottle. (Example: 1000 mg CBD)
- Find the bottle size in milliliters (ml). (Example: 30 ml bottle)
- Divide total mg by total ml. (1000 mg ÷ 30 ml ≈ 33 mg/ml)
If your dropper holds 1 ml, each full dropper gives you roughly 33 mg CBD. Half a dropper would be about 16–17 mg.
CBD Dose by Product Type
- CBD Oils / Tinctures – Taken under the tongue (sublingual). Onset is typically 15–30 minutes, with effects lasting 3–6 hours. Easy to adjust by fractions of a dropper.
- CBD Gummies / Capsules – Swallowed and digested. Onset is usually 45–90 minutes, with effects lasting 4–8 hours. Check the mg per gummy or capsule.
- CBD Vapes / Inhalation – Effects can be felt within minutes and may last 1–3 hours. Because inhalation is more efficient, you may need a lower mg amount than with edibles.
- CBD Topicals – Applied directly to the skin. These target a local area and generally do not have strong whole-body effects. Dose is measured by how much product you apply, not mg per serving.
CBD Titration: “Start Low & Go Slow”
Here’s a simple titration strategy you can follow:
- Choose a low starting dose (for example, 10–15 mg once daily).
- Stay at that dose for 4–7 days while monitoring how you feel.
- If you’re not noticing any change and feel good overall, increase by 5–10 mg.
- Give your body a few days at each new dose before adjusting again.
- Once you find your “sweet spot,” stay consistent and adjust as your needs change.

THC Dosage Guide
THC (tetrahydrocannabinol) is the primary intoxicating cannabinoid in cannabis & hemp-derived THC products. It can support mood, relaxation, and comfort—but it can also cause impairment and unwanted side effects at higher doses or in sensitive individuals.
With THC, it’s especially important to start low, be patient, and understand your own tolerance and local laws.
Common THC Dosing Ranges (Edibles & Tinctures)
| THC Amount (per serving) | Experience Level | What to Expect (varies by person) |
|---|---|---|
| 1 – 2.5 mg THC | Microdose / very sensitive / first-time | Very mild body effects, subtle mood shift; good for “testing the waters.” |
| 2.5 – 5 mg THC | Beginner / low dose | Noticeable relaxation or euphoria for many; good starting range for most adults. |
| 5 – 10 mg THC | Intermediate | Stronger effects; more euphoria and body sensation. Best once you understand your response. |
| 10 – 20 mg THC | Experienced | Potent for many users; higher chance of side effects like anxiety, dry mouth, or dizziness. |
| 20+ mg THC | Very experienced / medical | Very strong effects. Not recommended for new users. Higher risk of uncomfortable experience. |
THC affects everyone differently. Age, body weight, sex, metabolism, and what you’ve eaten can all change how a dose feels. When in doubt, take less than you think you need.
Edibles vs. Inhalation: Timing & Effects
- Edibles (gummies, baked goods, capsules) – Onset usually takes 60–90 minutes and can last 4–8 hours or more. Do not re-dose too soon; many uncomfortable THC experiences happen when people think it isn’t working and eat more too quickly.
- THC Oils / Tinctures – Sublingual onset is typically 30–60 minutes with effects lasting several hours.
- Vapes / Flower (inhalation) – Effects are felt within minutes and generally last 1–3 hours. It’s easier to “creep up” slowly with small inhalations.
THC Safety Tips
- Start with 1–2.5 mg (or just 1 small puff) if you’re new to THC.
- Wait the full onset time before deciding to increase your dose.
- Never drive or operate heavy machinery after consuming THC.
- Avoid mixing THC with alcohol or other substances.
- Keep all THC products locked away from children and pets.
- If you accidentally take too much, stay calm, hydrate, and rest in a safe place. The feeling will pass with time.

CBD:THC Ratios & How to Use Them
Many products combine CBD and THC in specific ratios. CBD can help “balance” some of THC’s intense effects while both cannabinoids work together to support comfort and relaxation.
| CBD:THC Ratio | Example Per Serving | Typical Use Case |
|---|---|---|
| 20:1 or 10:1 (CBD rich) | 20–25 mg CBD + 1–2.5 mg THC | Very gentle, minimal intoxication for most; good for daytime comfort or new THC users. |
| 5:1 or 4:1 | 20 mg CBD + 4–5 mg THC | Balanced support with mild euphoria; great for evening wind-down for many users. |
| 1:1 | 5–10 mg CBD + 5–10 mg THC | Stronger effects; may support more intense comfort needs but higher chance of intoxication. |
Ratios are a helpful framework, but the actual mg amounts matter just as much. When trying a new ratio product, start with a low THC amount and increase slowly.

How to Choose Your Dose Step-by-Step
- Clarify your goal. Are you looking for daily balance, workout recovery, or better sleep? Your goal influences both cannabinoids and dose.
- Decide CBD, THC, or a ratio. If you’re new or sensitive to THC, start with CBD-only or a high CBD:THC ratio.
- Pick your product type. Oils/tinctures for precise control, gummies for convenience, vapes for rapid onset, topicals for local areas.
- Start with a low mg amount. For example, 10–15 mg CBD or 2.5 mg THC (or less) for your first few sessions.
- Stay consistent for several days. Take the same dose at the same time each day to understand how it affects you.
- Adjust gradually. Increase in small steps (5–10 mg CBD or 1–2.5 mg THC) only after you’ve given your body time to respond.

Safety, Side Effects & Legal Considerations
Possible Side Effects
CBD may cause, especially at higher doses:
- Dry mouth
- Drowsiness or fatigue
- Changes in appetite or digestion
- Interactions with certain medications
THC may cause, especially at higher doses:
- Impaired coordination and judgment
- Anxiety, paranoia, or racing thoughts
- Increased heart rate
- Dizziness, nausea, or dry mouth
Drug Testing
Many drug tests are designed to detect THC. Full-spectrum CBD products contain small amounts of THC and may cause a positive result. Even some “THC-free” products may carry a small risk of triggering tests depending on sensitivity and usage. If drug testing is a concern, look for THC-free products and review third-party lab reports.
Legal Notes
- Hemp-derived products must contain < 0.3% Δ9 THC by dry weight at the federal level in the U.S.
- State and local laws can be more restrictive. Always check the rules where you live.
- Products are for adults of legal age only. Keep out of reach of children and pets.

CBD & THC Dosing FAQ
How much CBD should I take if I’m brand new?
A common starting point is 5–10 mg of CBD once per day. If after several days you don’t notice any change and feel good overall, you can increase by 5–10 mg at a time until you find your sweet spot.
What’s a safe THC dose for first-time edible users?
For most adults, 2.5–5 mg THC is considered a low, beginner-friendly edible dose. If you’re very sensitive, start even lower (1–2 mg). Always wait at least 60–90 minutes before deciding to take more.
How long do CBD and THC effects last?
For most people, inhaled cannabinoids last 1–3 hours, tinctures 3–6 hours, and edibles 4–8+ hours. Everyone’s metabolism is different, so your experience may vary.
Will CBD or THC show up on a drug test?
THC and its metabolites are the primary target of many drug tests. Full-spectrum CBD products contain trace THC and may cause a positive result. If drug testing is a concern, consider broad-spectrum or THC-free products and review lab reports carefully.
Can I take CBD and THC together?
Yes, many people find that combining CBD and THC in a ratio works well for them. Higher CBD with lower THC (for example 10:1 or 5:1) is often a gentler option. Always start with low THC amounts and increase slowly.
Does body weight matter for dosing?
Body weight, metabolism, and sensitivity can all influence how cannabinoids feel, but there is no single “correct” formula. Use weight-based guidelines only as a rough reference and adjust based on how you feel, not just the numbers.
Can I increase my CBD or THC dose if I don’t feel anything?
If you’ve taken a low dose, waited a reasonable amount of time (especially with edibles), and feel no changes or side effects, it can be reasonable to increase slowly on a different day. Never keep re-dosing quickly in the same session, especially with THC edibles, as the effects can “catch up” all at once.
Should I talk to a doctor before taking CBD or THC?
Yes, especially if you have health conditions, take prescription medications, are pregnant, or breastfeeding. A healthcare professional who understands cannabinoids can help you integrate CBD or THC safely into your routine.
