Recall Forensics: The Michigan Nuggz Nectar Recall — the validation failure behind it

Team ValidLeaf · September 2026 · 5 min read

Recall Forensics is our series tracing real cannabis product recalls to the specific validation gap that caused them. Every fact comes from public regulator records or trade-press reporting of those records — no speculation, no invented causes. This case packed three failures into one recall: potency over the limit, potency varying between units, and a label that miscounted the servings. Three symptoms, one root cause.

What happened

On August 20, 2026, Season 3, LLC of Kalamazoo, in coordination with the Michigan Cannabis Regulatory Agency (CRA), announced a voluntary recall of certain Nuggz Nectar Infused Drink 200mg products. Testing indicated the drinks might exceed allowable THC concentration limits; the company was also investigating potential potency variability and homogeneity — and the products carried an inaccurate serving-count declaration. Nine flavors were affected: Blue Razz, Cherry Bomb, Grape, Green Apple, Hulk Juice, Lemonade, Mango, Tropical Punch, and Watermelon Splash. The drinks were sold at licensed retail locations in Muskegon, Lansing, Battle Creek, and Kalamazoo, and the company was working with retailers to retrieve and dispose of remaining inventory. No adverse health effects had been reported as of August 18 (CRA press release).

Note the structure of the failure: the first two problems — too much THC, and THC distributed unevenly — are about the process. The third — the wrong serving count on the label — is about the paperwork. When all three show up together, the process was never demonstrated to be under control.

The validation gap: process validation (plus labeling)

Cannabinoid beverages are among the hardest products to make consistently: THC is oil-soluble, the drink is water-based, and keeping the two evenly distributed requires a genuinely validated emulsification and mixing process. THC over the limit plus potency variability between units says the process was not under control — the batch-to-batch and unit-to-unit consistency that process validation exists to prove.

The controls that close this gap:

• Mixing and homogenization validation. Demonstrated uniform THC distribution through the batch — at worst-case batch sizes, mixing times, and hold times, with acceptance criteria defined before the study runs.
• Stratified in-process sampling. Samples taken across the fill — beginning, middle, end of the run — not one composite sample per batch. Variability hides where you don't sample.
• Label claims derived from validated data. The serving count and THC-per-serving statements should trace back to demonstrated fill-volume control and potency data — which is exactly where this recall's third failure lived. (See our Recall Forensics case on the Ohio Standard Farms recall for the labeling-control discipline.)
• Revalidation triggers. New flavors, new equipment, scale-up, a changed emulsifier — each one re-qualifies the process. A process validated for one formulation is a rumor for the next.

Worth noting: Michigan's own technical guidance for infused beverages specifically calls out homogeneity testing as a requirement. When the regulator tells you exactly what it will check, failing that check is a choice — and an expensive one.

How a GMP Readiness Assessment catches it

This is exactly the failure pattern a GMP Readiness Assessment is built to find. Over four weeks, it reviews:

• Process validation status — is there documented evidence (not tribal knowledge) that your process consistently delivers the labeled potency?
• In-process sampling plans — do they actually detect variability, or just confirm the average?
• Label claim substantiation — can every number on the label be traced to data?
• Revalidation triggers — when formulations or equipment change, does anything get re-qualified?

It closes with a gap assessment, a remediation roadmap, and starter IQ/OQ/PQ templates — so the fix starts before the next batch fills.
