THC Calculator

Calculate THC dosage for edibles, estimate onset time, and understand potency based on weight.

THC Dosage Calculator

THC (tetrahydrocannabinol) is the primary psychoactive compound in cannabis. Proper dosing is important for a safe and comfortable experience, especially with edibles where effects are delayed and longer-lasting than smoking.

General Dosing Guide:
Microdose: 1-2.5 mg — Subtle effects, focus
Low: 2.5-5 mg — Mild euphoria, relaxation
Moderate: 5-15 mg — Stronger effects, altered perception
High: 15-30 mg — Strong effects, experienced users
Very High: 30+ mg — Very strong, not recommended for beginners
⚠️ Important: Start with a low dose (2.5-5mg) and wait at least 2 hours before consuming more. Edibles take 30 minutes to 2 hours to take effect. This calculator is for legal jurisdictions only.

Factors Affecting Response

  • Body weight: Larger individuals may need slightly more
  • Tolerance: Regular users need more for the same effect
  • Metabolism: Faster metabolism = faster onset
  • Food in stomach: Eating beforehand slows absorption
  • Individual sensitivity: Genetics play a major role

How to Use

Select your experience level and enter your body weight. The calculator suggests a starting dose range based on general guidelines.

Edibles vs Smoking

Edibles produce different effects than smoking: slower onset (30-120 min vs instant), longer duration (4-8 hours vs 1-3), and often stronger effects because THC is metabolized differently through the liver.

Safety Tips

Start low and go slow. Do not drive or operate machinery. Store edibles securely away from children and pets. Stay hydrated and have snacks available.

Frequently Asked Questions

Beginners should start with 2.5-5mg. Wait at least 2 hours before taking more.
Edibles typically take 30 minutes to 2 hours for onset, with peak effects at 2-4 hours.
Edible effects typically last 4-8 hours, sometimes longer depending on dose and individual metabolism.
While THC is not lethal, taking too much can cause extreme discomfort, anxiety, and paranoia. Start low and go slow.
When eaten, THC is processed by the liver into 11-hydroxy-THC, which is more potent and longer-lasting.
Weight is one factor, but tolerance and individual sensitivity matter more. Body weight provides a rough adjustment.
