All marijuana products1
Copy the two sentences exactly as one block — the rule prescribes the words. It is element M, the last item in the fixed A-to-M order. Missouri's closed list (19 CSR 100-1.120(1)(C)4) permits nothing beyond the required elements except information required by other local, state or federal law, so adult-use, do-not-drive, pregnancy and out-of-state-transport statements common in other states are prohibited on a Missouri label.
Applies to every marijuana product carrying the full label. Prerolls need no label on the paper itself, and seeds and plants carry a reduced label ("Marijuana", the universal symbol, strain information, and for plants a propagation date) that does not include this warning.
Exact text required

Missouri Department of Health and Senior Services (DHSS), Division of Cannabis Regulation prescribes this wording. Reproduce it character for character, including capitalization and punctuation.

Cognitive and physical impairment may result from the use of marijuana. Keep out of reach of children.

Packaging & Labeling Rules

Child-ResistantEvery Missouri marijuana package must be child-resistant and must not appeal to kids.
  • Use certified child-resistant packaging.
  • The same package must also be opaque and resealable.
  • Packaging must be constructed from FDA-approved food contact substances — a material specification, not an artwork one.
  • Seeds and plants are outside all three requirements.
  • No design element that is attractive to children.
  • Package must be produced and packaged to protect public health.
Before you print
  • Get the CR certification documentation from the supplier before item approval — DCR reviews the package, not just the artwork.
Notes on this section — 3
  • Where product sits in a series of containers, the container closest to the product carries the child-resistant, opaque and resealable requirement — excluding methods of administration and wrappers.
  • The food-contact requirement runs the other way: it lands on the container closest to the product including methods of administration or wrappers, unless the department approves applying it to a different container in the series.
  • That difference decides which part of a nested pack has to be certified. Read it before quoting a jar-in-carton or a wrapped-insert format.
19 CSR 100-1.120(1)(B)3; 19 CSR 100-1.120(1)(B)4
LabelingMissouri fixes both what goes on the label and the order it runs in — thirteen elements, A to M, read top to bottom and left to right, and nothing else may appear.
  • Element A first: all active and other ingredients, including solvents.
  • Exact total weight: grams for dried unprocessed marijuana, concentrates, pre-rolls and infused pre-rolls; milligrams of delta-9-THC for infused products other than infused pre-rolls.
  • Eight named cannabinoids per serving or dose, listed in milligrams: delta-9-THC, delta-9-THCA, CBD, CBDA, CBN, THCV, CBDV and delta-8-THC. All eight, not a selection — lay out panel space for the full set.
  • Servings or doses per package.
  • Instructions for use.
  • Estimated length of effect time.
  • A best-if-used-by date.
  • Originating licensee's license number.
  • Testing licensee.
  • Statewide track-and-trace tag number.
  • Terpene results, if the product was tested for terpenes.
  • Department-issued product packaging approval number.
  • Element M last: the required warning statement.
  • Closed list — no extra warnings, marketing claims or courtesy statements, unless another local, state or federal law requires them.
  • Prerolls: no label required on the paper itself.
  • Seeds and plants: reduced label only — Marijuana, the universal symbol, strain information, and a propagation date for plants.
  • Ingestible flavor components may be grouped (for example, lime flavoring) instead of itemized.
  • A dispensary barcode may sit outside the label area if it covers no required information.
Notes on this section — 2
  • Grouped flavors and the outside-the-label barcode are DCR variances (2/5/2024 and 10/18/2024), not rule text — confirm each still stands at item approval before a plate is cut.
  • Under the closed list, do not add elements to a seed or plant label to make it look more complete.
19 CSR 100-1.120(1)(C)2; closed list at 19 CSR 100-1.120(1)(C)4; reduced labels at 19 CSR 100-1.120(1)(C) introductory text and (1)(C)3; DCR variances of 2/5/2024 and 10/18/2024
THC SymbolA red-and-white diamond holding THC with an M beneath it, displayed prominently on the package.
  • Edibles at 10 mg THC or more: 0.5 in x 0.5 in, measured point to point, on the front of the package.
  • All other product types: no stated size and no stated panel — prominent display only.
  • Infused products: print the package total THC in milligrams directly under the diamond.
  • The word Marijuana must be at least as large as any other word on the package.
  • Royal Supply house standard — stricter than the Missouri rule. Hold 0.5 in x 0.5 in on the front panel across every Missouri SKU so one asset clears all types.
Notes on this section — 2
  • The 0.5 in front-panel standard for non-edibles is our recommendation, not a Missouri requirement.
  • DCR can approve an alternative placement for non-edible types — raise it at item approval if the front panel does not work.
19 CSR 100-1.120(1)(C)1; s. 195.805.2 RSMo
Health WarningsOne warning, prescribed word for word, printed last on the label.
  • Print exactly: Cognitive and physical impairment may result from the use of marijuana. Keep out of reach of children.
  • It is element M — the final item in the A-to-M order.
  • The state sets no minimum type size for the warning.
  • Royal Supply house standard — not traced to a Missouri rule. Floor: set it at 7 point or larger so it holds up at final trim size.
  • Add no other warning — no adult-use, do-not-drive, pregnancy or out-of-state-transport text.
Notes on this section — 2
  • The 7-point floor is our legibility recommendation, not a compliance threshold — do not design around it as one.
  • Live artwork still carrying Missouri's pre-2023 medical transport and medical-use paragraph should be corrected before the next print run; it did not carry into the unified rules and will surface at item approval.
19 CSR 100-1.120(1)(C)2.M; closed list at 19 CSR 100-1.120(1)(C)4
Serving SizeMissouri wants exact milligram disclosure per serving; it caps package weight, not potency.
  • Mark exact milligrams per serving.
  • Show total serving and dosage information for the package.
  • Package ceiling: 3 ounces of dried, unprocessed marijuana or its equivalent.
  • No per-serving or per-package THC milligram cap — the milligram figures are disclosure, not a limit.
19 CSR 100-1.120(4); label content at 19 CSR 100-1.120(1)(C)2
Opaque PackagingPackages must be opaque, and DCR must approve the package before it can be sold.
  • Opaque material — contents not visible through the package.
  • Submit packaging and labeling for state review and approval before sale.
  • Build the approval cycle into the print schedule; the approval number itself is a required label element.
19 CSR 100-1.120
ResealablePackages must reseal, and the printed elements must not come off.
  • Resealable closure required on marijuana product packages.
  • Seeds and plants are exempt from the resealable requirement.
  • Required packaging and labeling elements must not be easily removed or separated from the package.
  • That constrains label stock, liner and adhesive selection, not just artwork.
  • Do not put a required element on a part of the package that has to be torn off to reach the product.
Notes on this section — 1
  • Two different subsections: the resealable requirement is at (1)(B)3, and the do-not-remove requirement at (5). Citing (5) alone leaves the resealability requirement unsupported.
19 CSR 100-1.120(1)(B)3; 19 CSR 100-1.120(5)
Notable RulesPackage design is limited to a closed list of permitted elements, and every SKU needs state approval before it sells.
  • One primary color, plus up to two logos or symbols in a different color.
  • A logo or symbol may be no wider than the length or the height of the word Marijuana on the package.
  • Permitted elements are closed, not illustrative: palette, logos, product name, side-effect text, QR code.
  • The same closed list expressly extends to exit packaging.
  • No packaging in the shape of a human, animal, or fruit.
  • All marijuana products require state review and approval of packaging and labeling before sale.
  • Humidity control packets are allowed if they use FDA-approved food contact substances and the item approval application notes their inclusion.
Before you print
  • A permission the agency granted, not a mandate. Confirm it still stands.
Notes on this section — 2
  • As of September 2026 no amendment to 19 CSR 100-1.120 has been made. The codified rule still carries its original history: filed January 20, 2023, effective July 30, 2023.
  • 19 CSR 100-1.070 and 19 CSR 100-1.100 do not govern packaging — ignore them if cited to you.
