HHC has been illegal in Ireland since last year.
Under-18s should not have access to HHC-containing vapes.
That's the message from the Athlone Drug Awareness Group, after the HSE tested 76 vape products of which 28 of them contained Hexahydrocannabinol.
HHC is a semi-synthetic cannabis alternative commonly sold in Ireland in e-cigarettes or vape pens.
It is being sold through the black market and high-street shops, despite the Government classifying it as an illegal drug in July last year.
Treasurer of the group Jim Henson says businesses that sell illegal vapes to children shouldn't be in operation:
