A warning has been issued to parents by Thames Valley Police via social media after the Wantage Neighbourhood Team found drugs in packaging "designed to appeal to kids".
The team says that the drugs they found are often sold via the post.
According to the force, these drugs can be "significantly stronger than other cannabis products" and can be "totally unregulated".

In a statement, the Wantage Neighbourhood Team said: "Wantage Neighbourhood team would love to talk to whoever is missing their drugs.
"Feel free to drop us a line and we can have a chat.
"For parents and other concerned parties we would just like to point out the packaging, definitely designed to appeal to kids.
"These are often sold via the post and can be significantly stronger than other cannabis products, totally unregulated.
"They could contain anything including synthetic drugs such as Spice or hallucinogens."
