1. What is THC Half Life?

The half-life of THC refers to the time it takes for half of the THC in the body to be eliminated. This varies based on individual metabolism, frequency of use, and other factors.

2. How Does the Calculator Work?

The calculator uses the half life equation:

Where:

• 0.693 — Natural logarithm of 2 (ln(2))
• Elimination Rate — The rate at which THC is cleared from the body (per day)

Explanation: The equation calculates how long it takes for THC concentration to reduce by half based on its elimination rate.

3. Importance of Half Life Calculation

Details: Understanding THC half-life helps estimate detection windows for drug tests and how long effects may last in the body.

4. Using the Calculator

Tips: Enter the elimination rate in 1/day (must be greater than 0). Typical THC elimination rates range from 0.1 to 0.2 1/day for occasional users.

5. Frequently Asked Questions (FAQ)

Q1: What's the average half-life of THC?
A: For occasional users, THC half-life is typically 1-3 days. For chronic users, it can be 5-13 days due to fat storage.

Q2: How does frequency of use affect half-life?
A: Regular users develop higher fat storage of THC, leading to longer half-lives as THC is slowly released from fat.

Q3: What factors influence elimination rate?
A: Metabolism, body fat percentage, hydration, exercise, and individual biochemistry all affect elimination.

Q4: Can this predict drug test results?
A: While helpful, drug test detection depends on many factors including test type, cutoff levels, and individual variations.

Q5: How accurate is this calculation?
A: It provides a theoretical estimate but actual half-life varies significantly between individuals.
