Missouri THC Diamond Warning Pre-Rolled Cones: Stay Compliant in the Show Me State

Pre-rolls are the fastest growing category in the cannabis industry and that is certainly the case in Missouri, where pre-roll sales revenues are already up by 26.1% this year compared to 2023, according to data from cannabis analytics firm Headset.

But like every state, Missouri has its own unique set of rules and regulations governing its cannabis program, including pre-rolled joints. Not only does Missouri have a very specific testing regimen that producers need to follow, all marijuana products in the Show Me State need to be "clearly and conspicuously labeled with ‘Marijuana’ printed at least as large as any other words used, as well as a prominently displayed universal symbol in red and white print."

The symbol required is a red and white diamond containing the letters THC and an "M."

Missouri Labeling Laws

Diving a little deeper, Missouri law specifically states "Except as specifically identified herein, labeling requirements apply to containers, wrappers, packages, and methods of administration that contain marijuana product, except seeds or plants. The labels required herein are not required on the paper for prerolls."

But while the labels may not be required on the rolling paper itself, the filter, or crutch, of a standard pre-roll cone can be considered the "method of administration." Therefore, to be safe, all Missouri pre rolls should feature the new label.

That’s why we have created a new designer cone that has the required warning logo and the word "marijuana" printed right on the filter itself, so you never have to worry if your pre-rolls are in compliance.

These special pre rolled cones come in two sizes – the 109mm full gram cone and our 84mm half-gram cone – and are available in both our ultra-refined white paper and our natural brown to meet your brand’s needs.

Missouri Testing

Missouri also has some of the strictest testing regulations in the country and require all cannabis products to be tested in its final form, including pre rolls. That means not only is the flower subject to testing, but your paper and any other ingredients as well, since anything can cause a failure that can see the whole product lot destroyed.

Missouri is one of a handful of states that also tests its cannabis and cannabis products for the heavy metal chromium, which can damage the kidneys, liver and blood cells with the potential for renal and liver failure if untreated.

Because of that, Missouri pre roll manufacturers need to protect themselves – and their customers – by carefully selecting suppliers. After all, a study from California’s SC labs found that 11% of rolling papers they tested would fail that state’s testing regiment, which doesn’t even include Chromium, and that 90% of rolling papers contained heavy metals with more than 8% containing them at a rate above the allowable limits.

That’s why it’s so important for Missouri pre-roll manufacturers, in particular, to pay attention to their suppliers and make sure that the company from which they buy their paper takes testing as seriously as they do.

All Custom Cones USA pre rolled cones, including the ones labeled with the required Missouri warning symbol, are tested for pesticides, microbials and heavy metals to ensure that your paper never causes your pre-rolls to fail. We even have the Certificates Of Analysis available if you need them.

But to be sure, feel free to call the Pre-Roll Experts and request a sample that you can pack and have tested to make sure your product remains in compliance.

But either way, if you are a producer in the Show Me State, make sure you check out the new Missouri pre roll designer cones pre-printed with the required warning label. After all, why worry about compliance when you can be sure?
