With many cities legalizing recreational cannabis, there has been a proliferation of edible marijuana eaten instead of smoked.

Selling cannabis-infused food is supposed to be limited to adult customers under government regulations. However, one vendor reportedly sold sweets laced with tetrahydrocannabinol or THC, the psychoactive ingredient of marijuana, to students of two primary schools in St. Ann's Bay, Jamaica.

Some of the more than 60 pupils at St. Ann's Bay Primary and the nearby Ocho Rios Primary School experienced vomiting and hallucinations after eating the sweets. According to BBC, some children were sent to the hospital, with several put on an intravenous drip, Jamaica Education Minister Fayval Williams said.

The sweet packaging indicated that it contained 100 milligrams of the psychoactive substance Delta-8 THC, which is generally considered a high dose for an adult, BBC reported. The label also specified it was not to be sold to minors.

The sweets were produced by a company based in California, USA. Cannabis is legal in that state, but Jamaica disallows the import of edibles infused with cannabis.

A closely similar incident happened in Greece last month. A medical cannabis greenhouse near Almyros in Thessaly was broken into when many parts of the country were flooded due to Storm Daniel.

The intruders seeking refuge from the flood saw the plants and ate them.

Farm owner Yannis Bourounis told a local radio station that the trespassing flock of sheep consumed about 272 kilograms of weed.

Bourounis also said the sheep jumped higher than the goats as the herd got high from the plants.
