Key Takeaways

• Safe dosing is essential to avoid intense or long-lasting highs.
• THC potency, extraction efficiency, and serving sizes influence your edibles’ strength.
• A simple formula can help you calculate the approximate THC content per serving.

1. Introduction

Cannabis edibles offer a delicious and discreet way to enjoy the benefits of THC, but dosing them can be tricky. Unlike smoking or vaping, edibles take longer to kick in and can lead to unexpectedly strong effects if not appropriately calculated. This guide will walk you through dosing principles, introduce a simple dosing calculator, and share tips to ensure your edibles provide a pleasant experience.

2. Why Safe Dosing Matters

• Long-Lasting Effects: Edibles can last 6–8 hours or longer, making overconsumption incredibly uncomfortable.
• Delayed Onset: It may take 30–90 minutes to feel the effects, tempting some to consume more before the first dose kicks in.
• Individual Variations: Factors like body weight, metabolism, and tolerance can influence how strongly you feel THC.

3. Understanding THC Potency

• Cannabis Flower Potency: Measured in THC percentage (e.g., 15% THC). This indicates how many milligrams of THC are in each gram of flower.
• Extraction Efficiency: Some THC is lost during infusions (butter, oil). Assume 60–80% efficiency unless you have specific lab data.
• Desired Dose: Beginners often start with 5–10 mg of THC per serving, while experienced users might handle 20–30 mg or more.

4. Dosing Calculator: Step-by-Step Guide

Use this formula to estimate the total milligrams of THC in your infusion (butter, oil, etc.) and the mg of THC per serving.

Step 1: Gather Your Information

1. THC Percentage of Cannabis Flower (convert % to decimal, e.g., 15% = 0.15).
2. Weight of Cannabis (grams) used in the recipe.
3. Extraction Efficiency (assume 0.70 for 70% if unknown).
4. Number of Servings (portions) in the final recipe.

Step 2: Calculate Total Available THC

$$\text{Total THC (mg) }=\text{Weight of Cannabis (g )}\times 1000\times \text{THC Decimal }\times \text{Extraction Efficiency}$$

• Weight of Cannabis (g) × 1000 converts grams to milligrams.
• THC Decimal is the THC percentage in decimal form.
• Extraction Efficiency accounts for THC lost during processing.

Step 3: Determine THC per Serving

5. Using the Calculator: An Example

Let’s say you have:

• 10 grams of cannabis at 15% THC (0.15 in decimal).
• You assume 70% (0.70) extraction efficiency.
• You plan to cut your final edible into 20 servings.

Step 1: Total Available THC (mg)

10 g × 1000 × 0.15 × 0.70=1050 mg

So, your infused butter or oil has approximately 1050 mg of THC in total.

Step 2: THC per Serving

Each edible piece contains about 52.5 mg of THC, which is quite potent for most beginners.

6. Beginner-Friendly Dosing Guide

If new to edibles, follow the low and slow method:

✅ Start with 2.5–5 mg THC for your first time.
✅ Wait at least 1–2 hours before deciding to take more.
✅ Be patient! If you eat too much too fast, you may regret it later.

💡 Edible Strength Guide:

• Beginner-Friendly Dose: 2.5–5 mg THC.
• Intermediate Dose: 5–10 mg THC.
• Strong Dose: 10–20 mg THC (only for experienced users).

7. How Long Do Edibles Take to Kick In?

The effects of edibles don’t appear immediately.

💡 Tip: Always wait at least 90 minutes before taking more!

8. What to Do If You Take Too Much THC

Overconsumption can lead to anxiety, dizziness, nausea, or paranoia. If you accidentally take too much, don’t panic!

✔ Stay Calm – Remind yourself that no one has ever overdosed on cannabis.
✔ Hydrate & Eat Snacks – Drinking water or lemon juice can help balance the effects.
✔ Take CBD – CBD can counteract the effects of THC and help you sober up.
✔ Relax in a Safe Space – Lie down, breathe deeply, and distract yourself.
✔ Black Pepper Trick – Smelling or chewing black peppercorns can help reduce anxiety.

💡 Tip: The effects of a strong edible high may last 6–12 hours, so be prepared!

9. Frequently Asked Questions

Q: How long do edibles stay in your system?
A: THC from edibles can remain in your system for 24–72 hours, but traces may last weeks in heavy users.

Q: Do edibles hit harder than smoking?
A: Yes! Edibles are metabolized into 11-hydroxy-THC, which is stronger and longer-lasting than inhaled THC.

Q: Can I cut an edible in half to reduce the dose?
A: Yes! If a brownie contains 10 mg THC, cutting it in half gives you 5 mg THC per piece.

Q: Can you overdose on edibles?
A: No, but taking too much can cause an intense, uncomfortable high that lasts for hours.

10. Conclusion

Dosing cannabis edibles properly ensures a safe, enjoyable, and predictable experience.

✔ Start with 2.5–5 mg THC if you’re new to edibles.
✔ Be patient—wait at least 90 minutes before taking more.
✔ Always check labels or calculate dosage for homemade edibles.
