Inhalation THC Dosage Calculator Guidance

Inhalation is a popular method of consuming THC for its quick onset and precise dosage control. Use this simple dosage calculator chart to guide your THC inhalation experience:


Start Low: Begin with a low dose and gradually increase as needed. Everyone's tolerance levels vary, so it's important to find your optimal dosage.

Strain Potency: Consider the THC potency of the strain you're using. Higher THC levels may require smaller doses, while lower potency strains may require slightly higher doses.

Vape Pen

Vape pens are a healthy and efficient way to dial in your THC Oil dosage. Be sure to source your vape pens from a reputable source. Black-market vapes can cause serious health concerns.

Assumption 1: A vape pen contains 0.5g of THC Oil
Assumption 2: The THC Oil is at 80% Concentration (400mg THC)
Assumption 3: 100 puffs from a 0.5g vape pen
Conclusion: 1 puff = 4mg THC

Bowls / Pipes

If you are looking for a sizeable amount of THC in a single puff, dry-herb / flower might be one of your best bets. THC dosage for Bowls and Pipes are given as follows:

Assumption 1: A bowl contains 0.3g of flower
Assumption 2: 20% THC concentration (60mg THC)
Assumption 3: 5 puffs per bowl
Conclusion: 1 puff = 12mg THC

Joint / Blunt

Joints and blunts allow for a smaller THC per puff dosage, but typically burn longer and would allow for multiple hits, shared amongst fellow consumers.

Assumption 1: A blunt / joint contains 0.5g of flower
Assumption 2: 20% THC Concentration (100mg THC)
Assumption 3: 30 puffs from a 0.5g blunt / joint.
Conclusion: 1 puff = 3.33mg THC


While consuming THC from a bong might not be the most common approach, it is certainly an effective way to get a maximal dose.

Assumption 2: 20% THC Concentration (60mg THC)
Assumption 3: 3 hits from a bong bowl
Conclusion: 1 bong hit = 30mg THC

Dabs / Concentrate

Dabbing THC is a clean and effective way to get a sizeable dose. Be sure to follow best dabbing temperature guidance to make sure you don’t lose the other terpenes and trace cannabinoids.

Assumption 2: The dab is at 80% THC Concentration (400mg THC)
Assumption 3: An average-sized dab (size of a grain of rice) is 25mg (1/20th of the container)
Conclusion: 1 dab = 20mg THC

Assumption 2: 20% THC Concentration (60mg THC)
Assumption 3: 6 puffs from a vaporizer with 0.3g of flower
