No chemistry degree required. ## ON THE LAB REPORT ### COA Certificate of Analysis. The lab report on one exact batch. Your receipts. ### BATCH One production run, tracked by a batch, lot or sample ID. Match the code on your pack to the code on the COA. ### THIRD-PARTY LAB An outside lab that tests the product. Not the brand grading its own homework. ### ISO 17025 The international standard testing labs get accredited to. Somebody checks the checkers. ### POTENCY How much THC and friends are in the batch. The headline number. ### PANEL One group of tests on a COA, like potency, heavy metals or pesticides. More panels, more receipts. ### ND Not Detected. The lab looked and found nothing it could measure. For the bad stuff, ND is the dream. ### LOD Limit of Detection. The smallest amount the lab's gear can even see. ### LOQ Limit of Quantitation. The smallest amount the lab can put an exact number on. ### MU Measurement Uncertainty. The plus-or-minus. A good lab tells you how close its number is. ### PPM Parts per million. The ruler for tiny amounts, like contaminants. ### CFU/G Colony forming units per gram. How labs count microbes like mold and yeast. ### DRY WEIGHT The number with the water weight taken out, so every sample gets measured on the same scale. ### HEAVY METALS The panel for lead, arsenic, cadmium and mercury. You want low or ND. ### PESTICIDES The panel for what may have been sprayed on the plant. ### MICROBIALS The panel for mold, yeast and bacteria. ### RESIDUAL SOLVENTS The panel for anything left behind from extraction. ## THE CANNABINOIDS ### CANNABINOID The family name for compounds like THC, CBD and CBN. The stuff the lab is counting. ### THCA The raw form of THC that the plant grows. Heat turns it into Delta-9. ### DELTA-9 THC The classic THC. Already active, no heat needed. Listed in mg on edibles and drinks. ### DELTA-8 THC Delta-9's cousin. Same atoms, one double bond in a different spot. ### TOTAL THC Delta-9 plus THCA times 0.877. The honest combined number. ### DECARBOXYLATION The fancy word for heat turning THCA into Delta-9. Lighter does the chemistry. ### CBD Cannabidiol. A cannabinoid that shows up on a lot of labels, often next to THC. ### CBN Cannabinol. A cannabinoid that forms as THC ages. Shows up in some gummy blends. ### CBG Cannabigerol. Comes from CBGA, the parent acid a lot of other cannabinoids start from. ### RATIO How cannabinoids are split, like 1:1 THC to CBD. Equal parts, written short. ## THE FORMATS ### FLOWER The dried bud of the plant. Weighed in grams, labeled in percent. ### PRE-ROLL Flower already rolled and ready to burn. Zero rolling skills required. ### HASH Concentrated plant resin. The sticky crystals collected and pressed together. ### HASH-INFUSED ROLL A pre-roll with hash blended in. Slower burn, richer pull. ### CONCENTRATE **Drink concentrate** gets mixed before it's used. Our half-gallon Dope Daiquiri jug is one: one jug plus 2 1/2 gallons of water makes 3 gallons of slush. **Cannabis concentrates** are a different animal: oils, wax and shatter, made for vapes and dab rigs. ### READY-TO-DRINK RTD for short. Open it and pour, no mixing. Like our 8oz Dope Daiquiri pouch. ### RESEALABLE A lid that closes again. It's telling you the bottle is meant for more than one session. ### DISPOSABLE An all-in-one vape. Battery, hardware and oil in one body. Use it, then recycle it. ### DRAW-ACTIVATED No button. The device turns on when you inhale. ### GUMMY A chewy edible. Labeled in mg, per piece and per pack. ### SCORED A gummy with a line pressed in so it snaps clean in half. ### SERVING The amount the label counts as one. Could be one piece, two, or half. Always read it. ### MG PER PIECE How much is in one gummy. Pack total divided by piece count. ## FLAVOR AND AROMA ### TERPENES Aromatic compounds that give each strain its smell and taste. ### TRICHOMES The tiny sticky crystals on buds. Where the cannabinoids and terpenes live. ### STRAIN The name of a plant's genetic line. Often a hint at the flavor family. ### LIMONENE The citrus terpene. Same one in lemon and orange peels. ### MYRCENE A ripe-fruit, musky terpene. Think mango right on the edge. ### CARYOPHYLLENE The peppery, spicy terpene. Same family of notes as black pepper. ### PINENE The pine terpene. Smells like a walk in the woods. ## ON OUR SITE ### STATE GATE The step where you pick your state, so the site only shows what can ship there. Change it anytime from the pin button in the header. ### AGE CHECK The first stop on the site. Adults only. ### ADULT SIGNATURE Deliveries need an adult to sign, which is why we ship to street addresses, not PO boxes. Want the full breakdowns?

Every lab report we've got lives in the [COA library](/coa). **The Dog Says:** "Learn the words once. Read every label like you wrote it."
