Neville’s Haze – Strain Information

Neville’s Haze is a legendary cannabis strain known for its pure Haze genetics, extreme potency, and cerebral effects. This strain is a nearly pure sativa (90-100%) with a strong lineage tracing back to the original Haze genetics from the 1960s. Named after Nevil Schoenmakers, the founder of the first cannabis seed bank, Neville’s Haze has remained a favorite among connoisseurs for its uplifting high, psychoactive intensity, and long-lasting effects.

Genetic Background and Lineage

Neville’s Haze originates from a cross between a pure Haze and a Northern Lights #5 x Haze hybrid. The Haze lineage comes from a mix of Colombian, Thai, Mexican, and South Indian landrace strains, making it one of the most exotic and sought-after genetics.

Genetic Makeup:

• 90-100% Sativa (Some variations may have minimal indica influence)
• THC Content: 20-25%
• CBD Content: <1%
• Parent Strains: Haze x (Northern Lights #5 x Haze)

Morphology and Growing Characteristics

Neville’s Haze is known for its tall, lanky structure and long flowering period, making it a challenge for beginner growers. However, those who master its cultivation are rewarded with high yields and an exceptionally potent product.

Growth Features:

• Plant Height: Can reach over 6 feet (2 meters), especially outdoors.
• Flowering Time: 14-16 weeks (one of the longest among cannabis strains).
• Yield: Moderate to high (~450-600g/m² indoors, ~600g per plant outdoors).
• Climate Requirements: Prefers warm, tropical climates with high humidity tolerance.
• Resistance: Resistant to mold and pests, but prone to overfeeding issues.

Aroma, Flavor, and Terpene Profile

Neville’s Haze is known for its sharp, spicy, and citrusy aroma with hints of pine, earth, and herbal sweetness. The complex terpene profile contributes to both its effects and medical benefits.

Dominant Terpenes:

1. Myrcene (Herbal, earthy) – Contributes to mild sedative effects.
2. Limonene (Citrusy, lemony) – Provides mood enhancement and stress relief.
3. Pinene (Pine, fresh) – Aids in focus and counteracts THC-induced memory loss.
4. Caryophyllene (Peppery, spicy) – Has anti-inflammatory and pain-relieving properties.
5. Humulene (Earthy, woody) – Adds appetite-suppressing qualities.

Flavor Profile:

• Inhale: Strong citrus and pine with a spicy undertone.
• Exhale: Herbal sweetness with hints of earthiness and haze musk.
• Aftertaste: Lingering citrus and spice.

Methods of Ingestion and Their Scientific Basis

The most common methods of consuming Neville’s Haze include inhalation, oral ingestion, and sublingual absorption. Each method impacts the speed of onset, intensity, and duration of effects due to differences in cannabinoid metabolism.

A. Inhalation Methods (Smoking & Vaporization)

Inhalation allows rapid absorption of THC via the alveoli in the lungs, leading to quick onset and high bioavailability.

1. Smoking (Joints, Pipes, Bongs)

• Onset: 1-5 minutes (rapid due to direct absorption into the bloodstream).
• Peak Effects: 15-30 minutes.
• Duration: 2-4 hours.
• Bioavailability: ~25-30% of inhaled THC reaches systemic circulation.
• Pros: Immediate effects, easy dose titration.
• Cons: Combustion releases harmful byproducts (e.g., tar, carbon monoxide).

2. Vaporization (Dry Herb Vaporizers, Dab Pens)

• Onset: 1-3 minutes.
• Peak Effects: 10-20 minutes.
• Duration: 2-4 hours.
• Bioavailability: 40-50%, due to efficient conversion of cannabinoids at optimal temperatures (~180-200°C).
• Pros: Cleaner than smoking, preserves more terpenes, higher cannabinoid absorption.
• Cons: Requires vaporizer equipment, may be too potent for beginners.

B. Oral Ingestion (Edibles & Capsules)

Oral consumption leads to delayed onset but longer-lasting effects due to first-pass metabolism in the liver.

1. Edibles (Brownies, Gummies, Beverages)

• Onset: 30-90 minutes (depends on metabolism and stomach contents).
• Peak Effects: 2-3 hours.
• Duration: 6-12 hours (longest-lasting method).
• Bioavailability: 4-20% (low, due to digestive breakdown and first-pass metabolism).
• Metabolism: THC is converted into 11-hydroxy-THC, which is stronger and longer-lasting than delta-9-THC.
• Pros: Prolonged effects, ideal for medical use.
• Cons: Delayed onset makes dosing tricky; risk of overconsumption.

2. Capsules & Tinctures (Swallowed)

• Similar to edibles but provide precise dosing.
• Duration: 6-12 hours.
• Onset: 30-90 minutes.

C. Sublingual Absorption (Tinctures, Sprays, Dissolvable Strips)

Sublingual products bypass first-pass metabolism, allowing cannabinoids to absorb directly into the bloodstream through mucous membranes.

• Onset: 10-30 minutes.
• Peak Effects: 45-90 minutes.
• Duration: 4-6 hours.
• Bioavailability: ~40-50% (higher than edibles, lower than inhalation).
• Pros: Faster onset than edibles, discreet consumption.
• Cons: Effects may vary depending on saliva enzyme activity.

D. Topical & Transdermal Patches

While topicals (creams, balms) are mainly for localized pain relief, transdermal patches allow cannabinoids to enter the bloodstream.

• Onset: 30-60 minutes.
• Duration: 6-12 hours (depends on formulation).
• Bioavailability: ~30% for transdermals.
• Pros: Sustained release, avoids lung damage.
• Cons: Not suitable for psychoactive effects (except transdermal THC patches).

Factors Affecting Onset & Duration

A. Individual Factors

1. Metabolism Rate: Faster metabolism = quicker onset, shorter duration.
2. Body Fat Percentage: THC is stored in fat cells, affecting how long it stays in the system.
3. Tolerance Levels: Frequent users experience shorter and less intense effects.
4. Food Intake: Consuming edibles on an empty stomach speeds up onset but may cause more intense effects.

B. Product-Specific Factors

1. THC Concentration: Higher THC = more potent and longer effects.
2. Terpene Profile:
   • Myrcene enhances sedation and prolongs effects.
   • Limonene may increase absorption and improve onset speed.
3. Formulation: Lipid-based edibles (butter, oils) are absorbed better than water-based edibles.
