Marijuana Infused Products (Solids)

Cannabinoid isolate testing applies to a single cannabinoid refined to a white crystalline powder, typically 99% or higher, with terpenes and other cannabinoids removed. It is almost always an ingredient rather than a finished product.

For isolate submissions, important details include:

• Target cannabinoid: CBD, CBG, CBN, or other
• Winterisation, chromatography, and drying steps applied
• Stated purity from in-process testing
• Batch weight and packaging
• Products it will be formulated into

For a hemp-derived isolate, the critical number is not the target cannabinoid but the THC left behind. A product that is 99% CBD can still exceed the THC limit in the remaining 1%, so trace-level THC analysis is what actually determines whether the batch is compliant.

Common submissions include: CBD isolate, CBG isolate, CBN isolate, and purified cannabinoid powders.

Capsule testing applies to gelatin or vegetarian shells filled with cannabis oil or powder in a measured dose. Capsules exist to remove guesswork from dosing, so the analysis is as much about consistency between units as about the average.

For capsule submissions, important details include:

• Fill type: oil, powder, or emulsion
• Declared milligrams per capsule
• Shell material and size
• Encapsulation method and batch size
• Sealing and packaging format

An average that meets the label claim can still sit on top of wide variation between individual capsules. Testing multiple units from across a batch is what shows whether the encapsulation process is genuinely uniform — the entire premise of the format.

Common submissions include: softgels, powder-filled capsules, ratio formulations, and finished retail bottles.

Sugar wax testing applies to concentrate in which cannabinoids have crystallised out of the oil, producing a grainy texture of crystals suspended in a viscous base at roughly 60% to 90% THC. Crystallisation may be deliberate or the result of residual moisture.

For sugar wax submissions, important details include:

• Whether crystallisation was intentional
• Purge conditions and residual moisture
• Time from production to submission
• Approximate crystal to oil ratio
• Storage temperature since production

Like sauce, this is a two-phase material: crystals carry a different cannabinoid concentration from the oil around them. It also continues to change in the jar, so a sample tested fresh and the same jar tested weeks later can present differently even though nothing was added or removed.

Common submissions include: sugar wax, sugared concentrate, crystallised BHO, and grainy extracts.

Suppository testing applies to solid cannabis dose forms made on a fat base that melts at body temperature, for rectal or vaginal administration. Because these bypass the digestive tract, cannabinoids enter circulation without first-pass metabolism — which raises the stakes on dose accuracy.

For suppository submissions, important details include:

• Base: cocoa butter, coconut oil, or synthetic
• Declared milligrams per unit
• Moulding temperature and cooling method
• Unit weight and units per batch
• Cold-chain requirements in storage

Mucosal contact means the microbial threshold is stricter than for an oral edible. The fat base is also poured warm and set as it cools, so cannabinoids can settle toward the tip during that window unless the mould is cooled quickly enough to prevent it.

Common submissions include: rectal suppositories, vaginal inserts, cocoa butter units, and moulded dose forms.

Baked goods testing applies to brownies, cookies, and similar products made with infused butter or oil worked into a batter. Two processes stand between the input and the finished dose: how well the batter mixed, and what the oven did to the cannabinoids.

For baked goods submissions, important details include:

• Infused fat used and its tested potency
• Batch size and declared milligrams per unit
• Baking temperature and time
• Mixing method and duration
• Unit weight and portioning method

Calculating the dose from the infused butter overstates it. Oven heat degrades a fraction of the cannabinoids, and uneven batter distribution means one brownie from a tray can differ meaningfully from another. Only the finished, portioned unit answers what a customer receives.

Common submissions include: brownies, cookies, muffins, and portioned bake batches.

Chocolate testing applies to infused bars, truffles, and moulded confections where cannabis extract is incorporated into a cocoa butter base. The fat content that makes chocolate work is also what makes it one of the harder edible matrices to analyse.

For chocolate submissions, important details include:

• Chocolate type: dark, milk, or white
• Declared milligrams per piece and per package
• Tempering process and moulding method
• Point at which the extract was added
• Piece weight and pieces per unit

Cannabinoids are fat-soluble and cocoa butter is fat, so they disperse well — but that same affinity means the sample preparation has to separate them back out, and a method built for a water-based product will under-recover. Tempering also has to keep the mix uniform as it sets, or scored squares from one bar will not match.

Common submissions include: infused bars, truffles, moulded chocolates, and scored multi-dose units.

Hard lozenge testing applies to boiled sugar candies and mints carrying cannabis extract, intended to dissolve slowly in the mouth. Sugar has to reach very high temperatures to set hard, and cannabinoids have to survive that.

For lozenge submissions, important details include:

• Cooking temperature and hold time
• Stage at which the extract was added
• Declared milligrams per lozenge
• Emulsifier used to disperse oil in sugar
• Unit weight and pieces per package

Heat is the loss point. Extract added too early sees the full cook temperature and degrades, so producers add it late — which shortens the window available for even dispersion. Oil in a sugar syrup also wants to separate, making the emulsifier as important to the final result as the dose itself.

Common submissions include: hard candies, infused mints, lozenges, and boiled sugar batches.

Orally dissolving testing applies to thin films, strips, and fast-melt tablets that dissolve in the mouth so cannabinoids absorb through the mucosa. Onset is faster than a swallowed edible, which makes an accurate per-unit dose more consequential.

For orally dissolving submissions, important details include:

• Format: film, strip, or fast-melt tablet
• Declared milligrams per unit
• Film-forming polymer or tablet excipients
• Unit weight and dimensions
• Moisture barrier in packaging

These units are very light, often well under a gram, so a small absolute variation in cannabinoid content is a large percentage error against the label. Analysing them requires methods calibrated for that mass, and units are tested individually rather than pooled.

Common submissions include: dissolvable strips, oral films, fast-melt tablets, and sublingual units.

Soft chew testing applies to gummies, chews, and pastilles made on a gelatin or pectin base, the most widely sold edible format in the market. Each piece is a discrete dose, so the question is always what an individual gummy delivers.

For soft chew submissions, important details include:

• Base: gelatin or pectin
• Emulsion or distillate used and where it enters the process
• Declared milligrams per piece and per package
• Depositing method and mould size
• Piece weight and pieces per unit

Uniformity depends on the slurry staying mixed while it is deposited. If the actives settle in the hopper, pieces made at the start of a run differ from those at the end — which is why testing draws pieces from across a batch rather than from a single tray.

Common submissions include: gummies, soft chews, pastilles, and finished retail packs.

Solid fat testing applies to cannabutter, infused coconut oil, and similar saturated fats that solidify at room temperature. These are almost always ingredients — the base every downstream edible is dosed from.

For solid fat submissions, important details include:

• Fat type: butter, coconut oil, or shortening
• Plant material to fat ratio
• Decarboxylation and infusion conditions
• Straining method after infusion
• Batch weight and downstream products

Everything made from this inherits its concentration, so an inaccurate figure here propagates through an entire production run. Solidified fat also has to be melted and homogenised before subsampling, since cannabinoids can concentrate unevenly as the batch cools and sets.

Common submissions include: cannabutter, infused coconut oil, solid fat bases, and kitchen production batches.

Transdermal patch testing applies to adhesive systems that deliver cannabinoids through the skin into the bloodstream over hours. Unlike a topical, these are designed to reach systemic circulation, which places them closer to a pharmaceutical delivery format.

For patch submissions, important details include:

• Total cannabinoid load per patch
• Permeation enhancers in the formulation
• Adhesive matrix or reservoir design
• Patch area and intended wear time
• Backing material and release liner

Total content is what a laboratory can measure; how much crosses the skin over the wear period is a separate question the certificate does not answer. Cannabinoid distribution across the patch area also matters, since uneven loading means an inconsistent delivery rate over the hours it is worn.

Common submissions include: transdermal patches, matrix systems, reservoir patches, and adhesive delivery units.

Bath salt testing applies to Epsom or sea salt blends carrying cannabis-infused oil and, usually, essential oils and botanicals. The product is dissolved into bath water rather than applied to skin, which makes it the most dilute format in the catalogue.

For bath salt submissions, important details include:

• Salt base and grain size
• Infused oil used and how it was blended in
• Declared cannabinoid content per package or scoop
• Essential oils and botanicals included
• Package weight and moisture barrier

Blending oil into a dry crystalline salt rarely produces an even mix, so content can vary considerably scoop to scoop. The salt matrix also has to be dissolved out before analysis, and mineral salts interfere with detection unless the method accounts for them.

Common submissions include: infused bath salts, Epsom blends, bath soaks, and botanical salt mixes.
