A warning has been issued about the dangers associated with jelly sweets that contain cannabis components.

The Food Safety Authority of  Ireland has issued the warning, following a number of recent incidents whereby edible products containing significant levels of the cannabis component THC were intercepted by Gardai and the Revenue Customs Service.

In at least one incident, sweets containing cannabis oil were consumed by teenagers, one of whom suffered serious adverse effects and required hospitalisation.

The sweets were purchased online, with the packaging containing specific warnings that a significant concentration of THC was present.

The Food Safety Authority is warning that these sweets containing cannabis components are dangerous, particularly for young people, and says food should only be bought from reputable sources.

The FSAI is liasing with the HSE, Gardai and Revenue to detect and stop the import and sale of these dangerous products into Ireland.
