Six people in Tokyo have been taken to a hospital after eating gummies suspected to contain unregulated, marijuana-derived substances. Police are analyzing the gummies.
The gummies were handed out by a man in his 40s at an outdoor festival in Koganei City, western Tokyo, on November 4.
The people who ate the sweets developed symptoms such as dizziness and vomiting.
The festival organizers identified the man and notified the police. The man reportedly explained that he gave out the gummies because they tasted good.
Investigative sources say the gummies were made by a company in Osaka.
The label on the package said they contain marijuana-derived substances that are not regulated by law.
Several similar incidents have been confirmed since last month.
On November 3, four people in their 20s became ill and were taken to a hospital after eating gummies at Oshiage Station in Tokyo's Sumida Ward.
Officials at Japan's health ministry are urging caution, saying that unregulated substances are not necessarily safe.
