As Oklahomans rapidly embrace the use of marijuana, the health dangers are starting to surface.

The Oklahoma Bureau of Narcotics and Dangerous Drugs (OBNDD) recently issued a statement regarding collaborative efforts by OBNDD and the Oklahoma Medical Marijuana Authority (OMMA) to investigate THC edibles that caused hospitalizations.

More children are getting their hands on marijuana edibles, and for toddlers the effects can be serious or even life-threatening. Marijuana-related calls to the Oklahoma Center for Poison and Drug Information involving children have increased 10-fold since 2018, when medical marijuana legislation was passed in the state. 

In 2020, marijuana-related calls involving children jumped to 126 cases, up from just 13 in 2018. Reasons for the increase may be related to increased use of marijuana, people feeling more comfortable reporting adverse effects related to marijuana use or parents not storing marijuana products up and away from children. 

Scott Schaeffer, managing director of the Oklahoma Center for Poison and Drug Information reports, “Children are particularly sensitive to marijuana products. They may become unresponsive; blood pressure and heart rate are often affected as well. Children may mistake edible marijuana products (like candy or cookies) for regular food, and small children are at higher risk for overdose based on their weight. Many children who consume marijuana edibles require hospital admission due to the severity of their symptoms; we are aware of two children in the state who became seriously ill this week after eating edibles contained in packaging virtually indistinguishable from products available in a grocery or convenience store. In order to reduce the risk of injury or illness, store all marijuana products up and away from children just like any medication or chemicals.”

It’s not just children who can have adverse reactions. Adults sometimes call the poison helpline (1-800-222-1222) because they are inexperienced with marijuana, consume more marijuana edibles than required, or they mistake a marijuana product for regular food. The effects from edibles may take one or two hours to reach peak effect after the product is eaten.

 Symptoms of using too much marijuana may include:

  • Severe nausea or vomiting
  • Fast heart rate
  • Extreme confusion or anxiety
  • Panic and paranoia
  • Hallucinations and delusions

Pharmacists and registered nurses at the poison center are available 24 hours a day, seven days a week at (800) 222-1222. Please do not email the poison center or a member of the poison center staff, as poisoning emergencies are not handled through email.

OMMA would like to remind all patients about medication safety.

“The safety of our patients and our community is always the top priority of this agency,” said Dr. Kelly Williams, Director of the OMMA, “my team is working exceptionally hard and partnering with OBNDD to address this issue and evaluate the products for sale at our licensed dispensaries. We also recognize that patient and public safety efforts must continue once patients bring their medication home.”

All medications, including medical marijuana products, should be stored safely out of reach of children and pets. When a medical marijuana product looks like or is packaged in a manner similar to products that do not contain THC, including edible medical marijuana products, additional steps may be necessary to prevent accidental ingestion; the use of a medication lockbox is recommended.

Medical marijuana purchased in Oklahoma should meet all Oklahoma packaging and labeling requirements,  including opaque, child resistant packaging. Dispensaries are required to have the Certificate of Analysis (COA), the laboratory-issued document indicating the results of required safety and potency testing, on-site for each batch or product and available for review by patients. OMMA encourages patients to request and review this information to ensure that any product they may purchase has been properly tested.

Dispensaries are required to refuse to accept any products that do not meet all packaging and labeling requirements. OMMA has been increasing its compliance inspections and working alongside OBNDD to take action on all non-compliant products for sale at dispensaries. Those who are aware of improperly packed or labeled products should notify OMMA by submitting the information, including business name and address, product type and description, and photos if available, to the OMMA compliance team at [email protected].
