Cannabis industry news, regulatory updates, licensing requirements, and business insights for extraction companies.
How labs, QA leads, and regulators detect CBD-to-THC conversion: the solvents that flag each route, USP 467 limits, the isomer thresholds (delta-8, delta-10, iso-THC, olivetol), the zinc tell, and what the Colorado StayCon methylene chloride recall exposed.
IFC Chapter 39 is the chapter of the International Fire Code your fire marshal opens when a cannabis extraction permit lands on the desk, and it gives you exactly two ways to put an extractor in a building: the equipment is listed and labeled to UL 1389 (Section 3904.2.1), or a registered design professional writes [...]
THC remediation for hot hemp extracts: crystallization, flash chromatography, and degradation compared on THC floor, CBD recovery, cost per kg, and failure modes.
What GMP certification actually requires for a cannabis extraction lab: 21 CFR 211 and EU-GMP standards, ISO cleanroom classes, validation, cost, timeline, and the five audit failures that sink operators.
Most cannabis extraction labs treat waste as an afterthought until an EPA inspector or a state auditor treats it as a fine. Here is the number that should stop you: 100 kilograms per month. That is roughly 33 gallons of spent ethanol, and it is the line between being a Very Small Quantity Generator with [...]
Quick answer: A compliant cannabis solvent storage setup is governed by NFPA 30 for flammable and combustible liquids (ethanol, isopropanol, heptane, pentane, acetone) and by NFPA 58 for liquefied petroleum gases (butane, propane). Carbon dioxide is neither: a CO2 extraction room is an asphyxiation and pressure-vessel problem, not an NFPA 30 one. A single flammable [...]
A C1D1 extraction room needs explosion-proof electrical, 1 CFM/ft2 floor-level exhaust, negative pressure, and 25% LEL gas detection. Full spec and inspection checklist.
What a cannabis extraction consultant actually does, when to hire one, and why letting an equipment manufacturer spec your lab costs you six figures.
CO2 extraction rooms operate at 1,071 to 5,000 PSI above the carbon dioxide critical point (31.1C, 73.8 atm), with asphyxiation as the primary hazard rather than fire or explosion. They are NOT classified as C1D1 or C1D2. Those classifications apply to flammable solvents like butane and ethanol under NFPA 30 and NEC Article 500. CO2 [...]
The Classification Argument That Costs Operators $200,000 Someone on the conference call says the vapor count in the room is low, so they do not need electrical classification. Someone else says the total ethanol volume is under maximum allowable quantities, so they are exempt. A third person says the equipment is closed-loop, so there is [...]
