Police have issued an urgent warning after a spate of children eating cannabis sweets.

Officers in the Lake District told parents to beware of the snacks said to be stronger than a joint.

Cumbria has seen 'multiple' reports of kids eating the Class-B sweets, MailOnline reports.

Packets bound for Windermere have been seized with a man arrested on suspicion of possessing a controlled drug with intent to supply.

A spokesman for Cumbria Police said: 'The wrappers essentially look like any sweet packet so parents please be aware.

'Any of these sweets with a genuinely high THC content are both dangerous and illegal. THC is the main psychoactive compound found in cannabis.

The cannabis products are sold online mainly by US-based retailers

'Officers have already made a number of large seizures one of which was bound for Windermere. The local male involved has been released under police investigation on suspicion of possession of a controlled drug with intent to supply.'

The 'Stoner Patch' or 'Stoney Patch' snacks contain cannabis derivatives legal in most of the US - but not in Britain.

They are sold online, usually by American retailers, with ads saying they contain 500mg of THC and 0.1mg of CBD.

Cannabis sweets were intercepted by police officers en route to Windermere

Scientific studies say that an average joint is reported to contain about 100 - 122mg of THC. 

THC is the psychoactive substance that gets users 'high'. CBD, on the other hand, does not get people high and is not illegal.

CBD oil can be sold in the UK to help people ease pain relief and anxiety.

Products with a maximum THC content of less than 0.2 per cent are legal in the UK, according to the Home Office.
