Does Michigan require a cannabinoid hyperemesis warning on the package?

Michigan doesn't require a cannabinoid hyperemesis warning on the package.

The heavy box in state law is a pregnancy warning, and a St. Clair Shores parent wants a vomiting line added.

MCL 333.27958 still prints that pregnancy box for marihuana sold by a retailer or a microbusiness. Days of vomiting, and the hot-shower clue, already have a page: days of vomiting after daily use.

What warning does Michigan require on the package? #

The required box is a pregnancy warning inside a heavy line. MCL 333.27958 doesn't name cannabinoid hyperemesis.

Cannabinoid hyperemesis is the name for days of vomiting tied to heavy cannabis use. The other page walks that pattern. This page is the package.

Adult-use law tells the cannabis regulatory agency to set packaging rules. One of them is a warning on the outside of the package, in clearly legible type, surrounded by a continuous heavy line. The words are about pregnancy, breastfeeding, and a pregnancy someone is planning.

The same section tells marihuana retailers and microbusinesses to offer a pamphlet at the sale. The statute sizes it at 3.5 inches by 5 inches. The named topics are safety information on marihuana use by minors, and the poison control hotline number.

A Detroit retailer and a St. Clair Shores retailer sit under that same section. The box doesn't change because the shop is in Macomb County.

What the package rule requires	What she asked to add
Pregnancy warning inside a heavy line	A cannabinoid hyperemesis warning on the package
A pamphlet on youth use and the poison hotline	Materials for shoppers and for shop staff
Driving line, poison number, and age line in the agency rule	Reporting of diagnoses

The first two rows are MCL 333.27958. The third row's label lines are rule R 420.504. The ask is what she told ClickOnDetroit on October 23, 2026.

What does the pregnancy box actually say? #

Use by pregnant or breastfeeding women, or by women planning to become pregnant, may result in fetal injury, preterm birth, low birth weight, or developmental problems for the child.

MCL 333.27958 prints that sentence in capital letters, inside the heavy line, on the exterior of the package. The history line on the legislature page ends with a 2023 amendment.

You can read that box twice and still not see the word vomiting.

Medical provisioning centers carry the same boxed sentence in MCL 333.27206. A medical counter in Michigan isn't on a different pregnancy warning.

The statute still spells the plant marihuana. The jar in your hand is the package that section is talking about.

What else has to be on the label? #

R 420.504 adds a driving line, a poison-control number, and an age line. Cannabinoid hyperemesis isn't in that list.

Before a marihuana product is sold or transferred by a marihuana sales location, the container has to be sealed and labeled. The warning block has to include these statements:

• "It is illegal to drive a motor vehicle while under the influence of marihuana."
• "National Poison Control Center 1-800-222-1222."
• For a typical adult-use product: "For use by individuals 21 years of age or older or registered qualifying patients only. Keep out of reach of children."
• The pregnancy warning again, in clearly legible type, inside a continuous heavy line.

A product sold by a marihuana facility over the adult-use THC maximum uses a shorter age line. That line says registered qualifying patients only, and keep out of reach of children. It's still the same rule, and it still isn't a vomiting warning.

The rule's history line is 2020 and 2022, with a correction noted in the 2023 Michigan Register. The warning text above is that rule. Hyperemesis doesn't show up in the labeling section.

The label also has to carry the business name, the license number, the package tag, net weight, the lab's THC and CBD, activation time, the lab name, and the universal symbol the agency posts. Those lines say who grew it and what the lab measured. They don't name this syndrome.

What does the pamphlet have to cover? #

A sales location has to offer a pamphlet of at least 3.5 inches by 5 inches, with the poison hotline and at least two youth-use lines. Vomiting isn't one of the lines.

MCL 333.27958 names the size and two topics. Safety information on marihuana use by minors, and the poison control hotline number.

R 420.504 writes the handout in more detail. It has to include "National Poison Control Center Hotline 1-800-222-1222," plus at least two statements from a set about adolescence. A shop doesn't have to print every line.

Topic in the rule's list	Does the list name it?
Thinking and problem solving	Yes
Memory and learning	Yes
Coordination	Yes
Attention	Yes
School performance	Yes
Risk of mental health issues	Yes
Driving abilities	Yes
Potential for addiction	Yes
Cannabinoid hyperemesis	No

The rule's own wording for the first line is that marijuana use during adolescence may affect the developing brain negatively by impairing thinking and problem solving. The next lines follow that shape for memory, coordination, and attention. One more slot says the agency can approve some other statement and post it. The printed list still doesn't name days of vomiting.

That's why a parent can say the papers already talk about the developing brain and mental health. Those are youth-use lines. The October 23 story reported that Mindi Giorlando-Timmons wants this syndrome called out on its own, and that she says it differs from acute THC poisoning.

The keep-away sentence on the label is the storage line. The poison number is the poisoning hotline. Neither one is the warning she wants on the jar.

What did a St. Clair Shores parent ask for? #

She wants a package warning, materials for shoppers and shop staff, and reporting of diagnoses. She told the station she hopes to find bill sponsors.

ClickOnDetroit ran Erika Erickson's story on October 23, 2026. Mindi Giorlando-Timmons of St. Clair Shores said her daughter, Andy Timmons, is 19. Andy went to an emergency room on September 29 and was admitted, after vomiting, severe belly pain, and headaches. She was home about four days. The vomiting came back, she asked to return, and she was admitted again around 2 a.m.

Her mom said Andy had felt off and found relief in long, hot showers. Her mom said she hadn't heard the name until a nurse mentioned it at the hospital. The October 26 MichiGanja Report, by Kyle Kaminski, calls it suspected cannabis hyperemesis syndrome and says the 19-year-old was hospitalized twice.

She said she isn't trying to criminalize cannabis. The station lists three things she wants:

• Clearer warnings on the products.
• Educational materials for shoppers and for dispensary staff.
• Reporting of diagnoses so the condition can be tracked.

She told the station, "I don't want any other parent to have to go through this and not know this could happen." She also said, "You can't make a decision for yourself without information, and if you don't know that CHS is a potential possibility for you out there, you're not going to know to look it up."

Her letter, as the station described it, says the warnings she sees already cover pregnancy and breastfeeding, developing-brain risks, mental health, safe storage, and THC poisoning. She wants a prominent warning of its own.

One house in St. Clair Shores isn't a statewide count, and it isn't a Detroit rate. The pattern itself stays on the other page.

Does the reporting name a bill? #

No. She hopes to find sponsors, and the warning MCL 333.27958 prints today is still the pregnancy box.

The October 23 story says she hopes to find legislative sponsors for a warning bill. The October 26 MichiGanja recap repeats the label ask and doesn't attach a bill number.

• The station quotes her hope of finding sponsors.
• The Monday recap doesn't name a bill either.
• The compiled section still shows the pregnancy warning. Its history line ends with a 2023 amendment.

That's the package rule you can read on the jar this week. Hoping for sponsors isn't a sentence already printed on the bag.

What should a Detroit shopper look for on the jar? #

Look for the heavy pregnancy box, the driving line, the poison number, and the age line. A cannabinoid hyperemesis warning isn't in that required set.

On an adult-use jar, the check is short:

1. A heavy line around the pregnancy warning from MCL 333.27958.
2. The driving sentence, as R 420.504 writes it.
3. National Poison Control Center 1-800-222-1222.
4. The 21-and-older line, or the patients-only line if the product is over the adult-use THC maximum.
5. A pamphlet at the counter, at least 3.5 by 5 inches, with the hotline and at least two youth lines.

If the scare at home is days of vomiting, the jar check won't finish it. The hospital page walks that pattern.

FAQ #

Is cannabinoid hyperemesis named in the required package warning? #

No. The heavy-line warning is the pregnancy warning in MCL 333.27958.

The section covers marihuana sold through retailers and microbusinesses. The pamphlet topics in that section are youth use and the poison hotline.

She wants a vomiting warning added. The section doesn't print one.

What's printed inside the heavy box? #

A warning about pregnancy, breastfeeding, and planning a pregnancy, including fetal injury, preterm birth, low birth weight, and developmental problems for the child.

MCL 333.27958 sets those words in capital letters inside a continuous heavy line. R 420.504 repeats the same sentence on the label.

The box doesn't mention vomiting.

What phone number has to be on the cannabis label? #

The label warning has to include "National Poison Control Center 1-800-222-1222."

That's R 420.504. The pamphlet has to print the hotline too, as "National Poison Control Center Hotline 1-800-222-1222."

The number is the poisoning hotline. It isn't a cannabinoid hyperemesis line.

Does the sales pamphlet have to mention vomiting? #

No. It has to cover youth-use safety and the poison hotline, and the rule asks for at least two adolescence lines.

MCL 333.27958 names minors and the hotline. R 420.504 lists thinking, memory, coordination, attention, school, mental health, driving, and addiction.

Vomiting isn't on that list. A shop can add a statement the agency has approved and posted, and the printed list still doesn't name this syndrome.

Who asked for a cannabinoid hyperemesis package warning? #

Mindi Giorlando-Timmons of St. Clair Shores, after her 19-year-old daughter was admitted twice, first on September 29.

Erickson's October 23 report has both admissions and the label ask. The October 26 MichiGanja recap says suspected cannabis hyperemesis syndrome and two hospitalizations.

She also wants materials for shoppers and staff, and reporting of diagnoses.

Did lawmakers vote down a cannabinoid hyperemesis label? #

The reporting doesn't say that. She told the station she hopes to find sponsors.

The October 23 story quotes that hope. The MichiGanja recap doesn't name a bill number. MCL 333.27958 still shows the pregnancy warning.

Is the required box the same in Detroit and St. Clair Shores? #

Yes. Adult-use retailers across Michigan use the pregnancy box in MCL 333.27958.

St. Clair Shores is in Macomb County. Detroit is the TV market that ran the October 23 story. The statute doesn't write a separate warning for either city.

A medical provisioning center uses the same boxed sentence under MCL 333.27206.

What else did she ask for besides the package line? #

Materials for shoppers and dispensary staff, and reporting of diagnoses.

The October 23 story says she isn't trying to criminalize cannabis. She wants the name visible before a family has to learn it at the hospital.

The developing-brain lines and the mental-health line are youth-use options in R 420.504. She told the station those topics aren't a stand-in for this warning.

Does the poison number mean the label already covers this syndrome? #

No. The number is the poisoning hotline, and she says this syndrome differs from acute THC poisoning.

The label line is "National Poison Control Center 1-800-222-1222," from R 420.504. The October 23 story reported her split between the syndrome and acute THC poisoning.

Keep out of reach of children is the storage line. It isn't a vomiting warning.

Where's the page on days of vomiting? #

The hospital pattern, including the hot-shower clue, is on the emergency-visit page.

Read days of vomiting after daily use for the syndrome itself. This page stays on the package.

If you need words for a calmer visit later, how to tell a doctor you use cannabis is the script.

If this is your house #

You can want the jar to say the name, and you can still get care while the statute stays put.

I grow Michigan sun-grown flower for Divine Toke. This page is the label. If the vomiting won't quit, the hospital page is the one that walks the spell.

She wants the jar to say the name before a parent has to learn it from a nurse.
