Methods of Ingestion

Each method of ingestion varies in terms of bioavailability, onset time, and duration of effects. Below is a scientific breakdown of the most common ways to consume Purple Berry.

Inhalation (Smoking & Vaporization)

One of the most traditional and effective methods of Purple Berry cannabis consumption is inhalation, where cannabinoids quickly enter the bloodstream through the alveoli in the lungs.

Smoking (Combustion)
  • Bioavailability: ~30-40% THC absorption
  • Onset: Seconds to 5 minutes
  • Peak Effects: 30-60 minutes
  • Duration: 2-4 hours
  • Mechanism:
    • When cannabis is smoked, THC undergoes pyrolysis (heat-induced decarboxylation), converting THCA → THC.
    • The THC rapidly enters the bloodstream via lung capillaries, crosses the blood-brain barrier (BBB), and binds to CB1 receptors in the brain.
Vaporization (Vaping)
  • Bioavailability: 50-60% THC absorption
  • Onset: Seconds to 5 minutes
  • Peak Effects: 30-60 minutes
  • Duration: 2-4 hours
  • Mechanism:
    • Vaporizers of Purple Berry heat cannabis (320-400°F or 160-200°C), preserving terpenes and cannabinoids without combustion.
    • Delivers cleaner, more potent THC absorption compared to smoking.

Harmful ByproductsYes (tar, carbon monoxide)No combustion byproducts

Oral Ingestion (Edibles, Capsules, Tinctures)

Oral ingestion of Purple Berry involves first-pass metabolism through the liver, which alters THC into 11-hydroxy-THC (11-OH-THC), a more potent and longer-lasting metabolite.

Edibles & Capsules
  • Bioavailability: 4-20% (highly variable due to digestion and metabolism)
  • Onset: 30-90 minutes
  • Peak Effects: 2-4 hours
  • Duration: 6-12 hours
  • Mechanism:
    • THC is first metabolized by the liver into 11-OH-THC, which has a stronger affinity for CB1 receptors, leading to deeper, more intense psychoactive effects.
    • The slow absorption causes delayed onset but prolonged duration.
Sublingual (Tinctures, Oils)
  • Bioavailability: 20-35% (higher than edibles, lower than inhalation)
  • Onset: 15-45 minutes
  • Peak Effects: 1-2 hours
  • Duration: 4-6 hours
  • Mechanism:
    • Cannabinoids are absorbed directly into the bloodstream via mucous membranes under the tongue, bypassing first-pass metabolism.

Topical Cannabis (Creams, Balms, Lotions)
  • Bioavailability: Low (minimal systemic absorption, localized effects only)
  • Onset: 15-30 minutes
  • Duration: 2-4 hours
  • Mechanism:
    • THC and CBD interact with CB2 receptors in the skin, reducing localized pain and inflammation.
    • Since cannabinoids do not typically penetrate deeply enough into the bloodstream, topical products do not produce psychoactive effects.
Transdermal Patches
  • Bioavailability: High (up to 50-60% systemic absorption)
  • Onset: 30-90 minutes
  • Duration: 8-24 hours
  • Mechanism:
    • Transdermal patches contain permeation enhancers that allow THC or CBD to cross the skin barrier and enter the circulation for long-term release.

AbsorptionLocalized (CB2 receptors)Systemic (Bloodstream)
Onset Time15-30 minutes30-90 minutes
Duration2-4 hours8-24 hours
Psychoactive EffectsNoYes (if THC-based)

Factors Affecting Onset and Duration

Several physiological and metabolic factors influence how quickly and how long cannabis effects last.

Metabolism & Individual Physiology
  • Faster metabolism results in shorter onset and duration.
  • Liver enzyme activity (CYP2C9, CYP3A4) affects THC metabolism rate.
Fat-Solubility of Cannabinoids
  • Because THC is lipophilic, it attaches itself to body fat cells.
  • Regular users may experience a slower clearance rate, leading to longer effects over time.
Dosage & Tolerance
  • Higher doses of Purple Berry extend duration but also increase risk of overconsumption (edibles) or couch-lock (inhalation).
  • Chronic users may build tolerance, requiring higher doses for similar effects.
Method of Consumption
  • Inhalation offers fast but short-lived effects.
  • Edibles provide slower but longer-lasting effects.
  • Topicals are localized, with no psychoactivity.

  • Hang buds upside down in a cool, dark room with 50-60% humidity.
  • Maintain temperature at 60-70°F (16-21°C).
  • Allow drying for 7-14 days until stems snap when bent.
Curing Process
  • Store dried buds in glass jars at 65% humidity.
  • Open jars daily for the first 7-10 days to release excess moisture.
  • Curing for 3-6 weeks enhances smoothness, potency, and terpene retention.

Scientific Strategies for Enhancing Potency

To improve THC levels, terpene expression, and overall quality, these scientific techniques can be applied:

UV-B Light Exposure
  • Studies suggest exposure to UV-B radiation during flowering increases THC production.
  • Supplemental UV-B light for 2-4 hours daily in the last 3 weeks can enhance resin content.
Flushing Before Harvest
  • Flushing with pH-balanced water (pH 6.0-6.5) for 7-10 days removes excess nutrients.
  • Enhances flavor, smoothness, and overall smoking experience.
Cold Shock Technique
  • Lowering nighttime temperatures to 55-60°F (13-16°C) in the final week increases anthocyanin production, deepening the purple coloration of buds.
