What Is a Cannabis Extraction SOP? A cannabis extraction SOP is a written document that defines every variable in your extraction process with a target value, an acceptable range, and a defined action when you fall outside that range. It covers material inputs (solvent grade, starting material specs), process parameters (temperatures, pressures, hold times, solvent [...]
How to Purge Residual Solvents from Cannabis Concentrates: Solvent-Specific SOPs, State Limits, and Diagnostic Protocol Residual solvent purging for cannabis concentrates requires solvent-specific parameters: butane purges at 29-38C (85-100F) under 29+ inHg vacuum for 24-72 hours to reach sub-500 ppm. Ethanol purges at 40-50C (104-122F) under 28+ inHg for 8-24 hours. Propane purges faster than [...]
Nearly half of all licensed cannabis products on dispensary shelves carry THC labels that are wrong by more than 20%. A 2026 study found that 48% of licensed cannabis products deviated by more than 20% from their labeled THC concentration. A peer-reviewed PLOS One study of Colorado dispensary samples found average observed THC potency was [...]
Learn how to design a cannabis extraction lab the right way: layout, utilities, safety systems, workflow, and bottlenecks that actually matter.
Why Most Cannabis Beverages Fail Within 6 Months Cannabis nano emulsion for beverages requires droplet sizes between 20-100nm (PDI below 0.3) using high-pressure homogenization at 15,000-30,000 PSI or ultrasonication at 20-25 kHz. At 50nm average droplet size, THC bioavailability jumps from 6-10% (standard edible) to 50-85%, with onset dropping from 45-90 minutes to 10-20 minutes. [...]
What is a closed-loop extraction system, and why does it matter? If you want the downstream finishing side in more detail, read Residual Solvent Purging in Cannabis. It explains why slab geometry, vacuum depth, and solvent load decide whether your post-extraction workflow passes cleanly or keeps failing COAs. A closed-loop extraction system is a solvent-based [...]
RSO Dosing Protocol: Carrier Oil Science, Titration Schedules, and Why Most Guides Get It Wrong RSO dosing starts at 5mg THC (a rice grain of 60% oil), titrates to 25-50mg over 4-6 weeks, and the carrier oil you dissolve it in changes bioavailability by 3-4x. MCT oil delivers 2.5x the plasma THC of olive oil [...]
Novel Cannabinoid Synthesis from CBD: THCP, HHC, THCV, and the Chemistry Legislators Cannot Outrun THCP binds CB1 receptors at 33x the affinity of delta-9 THC. HHC resists oxidation because catalytic hydrogenation eliminates the double bond at C9. THCV acts as a CB1 antagonist below 10mg and flips to partial agonist above 20mg. Every one of [...]
Cannabis extracts degrade through three distinct mechanisms: THCa nucleation (shatter sugaring at supersaturation ratios above 1.3x, onset within 48-72 hours above 25C when THCa exceeds 65%), oxidative conversion (THC to CBN at 0.5-2.0% per month at 25C with light, 0.08-0.15% per month at 4C in dark), and terpene volatilization (myrcene half-life 8-12 weeks at 25C, [...]
Cannabis filtration media splits into two functional classes: depth filtration (celite, perlite, filter paper) that removes particulates by size exclusion at 1-25 micron pore ratings, and adsorptive chromatography media (activated carbon, bentonite clay, silica gel, alumina, magnesium silicate) that removes contaminants by chemical interaction. Activated carbon adsorbs 85-95% of color bodies but strips 8-15% of [...]
