- Bioavailability: 25 to 50 percent
- Onset: 1 to 5 minutes
- Peak Effects: 15 to 30 minutes
- Duration: 2 to 4 hours
Scientific Explanation:
- Upon inhalation, THC (delta-9-tetrahydrocannabinol) enters the lungs and diffuses rapidly into the bloodstream via alveolar absorption.
- First-pass metabolism is bypassed, allowing cannabinoids to reach the brain quickly via systemic circulation.
- Vaporization at lower temperatures (300 to 400 degrees Fahrenheit or 150 to 200 degrees Celsius) preserves terpenes such as limonene and pinene, enhancing flavor and therapeutic benefits.
Pros and Cons
Advantages:
- Rapid onset for immediate relief
- Efficient absorption due to high bioavailability
- Preserves terpenes, especially with vaping
Disadvantages:
- Potential lung irritation, especially from combustion
- Shorter duration compared to edibles
B. Oral Ingestion (Edibles & Capsules)
Method: Consuming cannabis-infused food, beverages, or capsules, allowing cannabinoids to be processed by the digestive system.
- Bioavailability: 4 to 20 percent
- Onset: 30 to 90 minutes
- Peak Effects: 2 to 3 hours
- Duration: 6 to 8 hours, sometimes up to 12 hours
Scientific Explanation:
- THC is metabolized by the liver (first-pass metabolism), converting delta-9-THC into 11-hydroxy-THC, a more potent psychoactive compound.
- This metabolite crosses the blood-brain barrier more efficiently, leading to stronger and longer-lasting effects compared to inhalation.
Pros and Cons
Advantages:
- Longer-lasting effects, ideal for chronic conditions
- No respiratory irritation
- More potent due to 11-hydroxy-THC conversion
Disadvantages:

- Bioavailability: 10 to 35 percent
- Onset: 15 to 45 minutes
- Peak Effects: 45 to 90 minutes
- Duration: 4 to 6 hours
Scientific Explanation:
- Sublingual administration bypasses first-pass metabolism, allowing cannabinoids to be absorbed directly into the bloodstream through capillaries under the tongue.
- This results in a faster onset than edibles but a longer duration than inhalation.
Pros and Cons
Advantages:
- Moderate onset and duration, making it an ideal balance
- Higher bioavailability than edibles
- Discreet and easy to dose
Disadvantages:
- Bitter taste, which some users dislike
