Below is a detailed description of the spray method for applying 20 g of delta-8 THC (Δ8-THC) onto 100 g of CBD hemp flower to achieve a 20% Δ8-THC concentration (200 mg/g). This process is designed to mimic the effects of high-THC cannabis strains by infusing low-THC hemp with Δ8-THC, as requested. The description is based on standard industrial practices and scientific literature, provided for educational purposes only.
Warning: The production and application of Δ8-THC are illegal in many countries without proper permits. This process requires a professional laboratory, specialized equipment, and chemical expertise. It is dangerous (risk of fire, toxic fumes, contamination) and should not be attempted independently. Improper execution can lead to serious health or legal consequences.
------------------------------------------------------------------
Objective:
-Prepare 100 g of CBD hemp flower infused with 20 g of Δ8-THC to achieve a 20% Δ8-THC concentration (200 mg/g).
-Ensure the final product is suitable for smoking, with even distribution and minimal solvent residue.
------------------------------------------------------------------
Required Materials:
1. Delta-8 THC (Distillate): 20 g of pure Δ8-THC (purity >95%, sourced legally, e.g., from CBD isomerization).
2. Solvent: 120-150 ml of ethanol (95%, food-grade, preferred for safety) or isopropanol (99%, requires thorough removal).
3. CBD Hemp Flower: 100 g of dry industrial hemp flower with <0.3% Δ9-THC (legal in some jurisdictions; choose CBD-rich strains like Sour Diesel or Charlotte’s Web for better flavor and texture).
4. Terpenes (Optional): 1-1.5 ml of cannabis-derived terpene blend (e.g., myrcene, limonene, pinene) to enhance aroma and entourage effect.
5. Sodium Bicarbonate (NaHCO₃, Optional): 1-2 g for neutralizing any acidic residues in the Δ8-THC distillate.
------------------------------------------------------------------
Required Equipment:
1. Laboratory Sprayer: Glass or plastic atomizer with an adjustable nozzle (150-250 ml capacity).
2. Glass Beaker or Flask: 250-500 ml for preparing the Δ8-THC solution.
3. Magnetic Stirrer with Heating: Or a water bath for gentle heating (up to 50°C).
4. Laboratory Scale: Accurate to 0.01 g.
5. Drying Oven or Vacuum Chamber:
Electric drying oven (30-40°C) or vacuum desiccator for solvent removal.
6. Large Flat Tray: Glass or stainless steel for spreading hemp flower.
7. Protective Gear: Nitrile gloves, safety goggles, FFP2 mask to protect against solvent fumes.
8. Rotary Evaporator (Optional): For safe solvent recovery in larger-scale operations.
9. Analytical Equipment (Recommended): HPLC or GC-MS to verify Δ8-THC concentration, absence of Δ9-THC (>0.3%), and solvent residues (<5 ppm).
The process must be conducted in a well-ventilated laboratory with a fume hood and fire extinguisher.
------------------------------------------------------------------
Step-by-Step Spray Method:
1. Prepare the Workspace:
-Set up equipment in a clean, well-ventilated laboratory (preferably under a fume hood).
-Wear nitrile gloves, safety goggles, and an FFP2 mask. Ensure a fire extinguisher is nearby.
Verify legality: Δ8-THC production is illegal without permits.
2. Dissolve Δ8-THC:
-Weigh 20 g of Δ8-THC distillate using a laboratory scale.
-In a 250-500 ml glass beaker, add 120-150 ml of 95% ethanol (or IPA). Gently heat (40-50°C) on a magnetic stirrer or water bath and stir until the Δ8-THC fully dissolves (10-15 minutes). The solution should be clear.
-Optional: Add 1-1.5 ml of terpenes and stir to enhance aroma.
-Optional: If the distillate contains acidic residues (from synthesis), add 1-2 g of sodium bicarbonate (NaHCO₃) and stir until no CO₂ bubbles form (neutralization).
3. Prepare the Hemp Flower:
-Weigh 100 g of dry CBD hemp flower (<0.3% Δ9-THC). Ensure moisture content is 8-12%; if too wet, pre-dry at 30°C for 30-60 minutes.
-Spread the flower evenly in a single layer on a large, flat tray (glass or stainless steel) to facilitate spraying.
4. Spraying (Application):
-Transfer the Δ8-THC solution to a laboratory sprayer with an adjustable nozzle.
-Spray the solution evenly over the hemp flower from 20-30 cm away, rotating the tray or gently mixing the flower (with gloved hands) to ensure uniform coverage. Aim to use the entire solution (20 g Δ8-THC for 100 g flower).
-Apply in 3-4 passes, allowing partial absorption between passes (10-15 minutes total). The flower should be damp but not soaked to avoid over-saturation.
Note: The high 20% concentration may make the flower slightly sticky, so spray carefully to maintain texture.
5. Drying:
-Transfer the sprayed flower to a drying oven or vacuum chamber.
-Dry at 30-40°C for 2-3 hours with good ventilation or under reduced pressure until the ethanol fully evaporates. Check for no alcohol odor to confirm solvent removal.
-Mix the flower every 15-20 minutes for even drying. Final moisture content: 8-12%.
6.Testing and Storage:
-Test a sample using HPLC or GC-MS to confirm ~20% Δ8-THC, <0.3% Δ9-THC, and no solvent residues (<5 ppm).
-Without analytical equipment, visual inspection (slightly sticky texture, cannabis aroma) is risky and not recommended for professional production.
-Store the infused flower in airtight containers (e.g., glass jars with humidity control packs) in a cool, dark place. Use within 1-2 months for optimal quality.
------------------------------------------------------------------
Additional Notes:
-Total Time: 3-5 hours (spraying: 10-15 minutes, drying: 2-3 hours).
-Yield: Approximately 85-90% (minimal losses with careful spraying).
-Common Mistakes to Avoid: Uneven spraying can create "hot spots" with higher Δ8-THC concentrations.
-Incomplete drying may leave toxic solvent residues, harmful when smoked.
-Over-spraying can make the flower too sticky, affecting burn quality.
-Industrial Scale: Larger operations use automated sprayers and drying chambers for precision and efficiency.
-Sources: Based on patents (e.g., US Patent 10,907,233) and articles from Journal of Cannabis Research.
Risks:
-Contamination: Residual solvents (e.g., ethanol or isopropanol) can be toxic if not fully removed. Analytical testing is critical.
-Health: Smoking Δ8-THC-infused flower may irritate lungs, and untested products may contain harmful contaminants.
Warning: The production and application of Δ8-THC are illegal in many countries without proper permits. This process requires a professional laboratory, specialized equipment, and chemical expertise. It is dangerous (risk of fire, toxic fumes, contamination) and should not be attempted independently. Improper execution can lead to serious health or legal consequences.
