Cases of illnesses linked to microdosing candies have more than doubled, with reports of seizures and the need for intubation, mechanical ventilation, and intensive care stays. But, there remains no recall of the products—microdosing chocolates, gummies, and candy cones by Diamond Shruumz—linked to the severe and life-threatening illnesses. In the latest update from the Food and Drug Administration late Tuesday, the agency said that it "has been in contact with the firm about a possible voluntary recall, but these discussions are still ongoing."

In the update, the FDA reported 26 cases across 16 states, up from 12 cases in eight states last week. Of the 26 reported cases, 25 sought medical care and 16 were hospitalized. No deaths have been reported.

Last week, the Centers for Disease Control and Prevention released a health alert about the candies. The agency noted that as of June 11, the people sickened after eating Diamond Shruumz candies presented to health care providers with a host of severe symptoms. Those include: central nervous system depression with sedation, seizures, muscle rigidity, clonus (abnormal reflex responses), tremor, abnormal heart rate (bradycardia or tachycardia), abnormal blood pressure (hypotension or hypertension), gastrointestinal effects (nausea, vomiting, or abdominal pain), skin flushing, diaphoresis (excessive sweating), and metabolic acidosis with increased anion gap (an acid-based disorder linked to poisonings).

More people have reported severe poisonings in an ongoing outbreak marked by people seizing and needing to be intubated after consuming microdose candies made by Diamond Shruumz, the Food and Drug Administration reported Tuesday.

There are now at least 12 reported cases across eight states. All 12 people were ill enough to seek medical care, and 10 needed to be hospitalized. The symptoms reported so far include seizures, central nervous system depression (loss of consciousness, confusion, sleepiness), agitation, abnormal heart rates, hyper/hypotension, nausea, and vomiting, the FDA reported.

In Tuesday's update, the FDA also expanded the products linked to the illnesses. In addition to all flavors of Diamond Shruumz's Microdosing Chocolate Bars, the agency's warning now covers all flavors of the brand's Infused Cones and Micro Dose and Macro Dose Gummies.
