Education bosses have vowed to take a “strong stance” after reports of pupils bringing drugs into school.

Police were called to Durrington High School in The Boulevard, Worthing, last week after reports of youngsters having cannabis with them.

While no drugs were found by officers a cannabis grinder, which is used to shred the bud of the plant so it can be smoked, was confiscated.

Sussex Police said the matter had been left with the school to deal with.

Head teacher Sue Marooney said: “Student wellbeing and safety is our priority.

“We always take a strong stance against anything which threatens this and when appropriate will involve the police.

“We would not wish to comment on individual students.”

According to the Government cannabis is the most widely-used illegal drug in Britain, although the number of people using it is believed to be falling.

It is a class B drug, which means it is illegal to possess, give away or sell.

The maximum penalty for possession is five years in jail while supplying someone can result in a fourteen year prison term and an unlimited fine.

More common actions include a police warning, a reprimand, a formal caution or a fixed penalty fine.

A spokesman for West Sussex County Council, which runs the school, said: “Safety and wellbeing of young people is at the centre of the county council approach to all matters.

“All schools have robust policies on drugs and the county council encourages its schools to have a well planned drug education programme, a drug policy developed in consultation with the whole school community, which outlines the school’s response to all drug matters.

“We also encourage strategies in place to identify and support young people for whom drugs may be a problem and staff who are confident and skilled in addressing drug issues.”

A spokesman for Sussex Police said: “No drugs were found and no further action was taken. The matter has now been left in the hands of the school.”

Earlier this year officers in Worthing and Adur carried out an education drive and leaflet drop in a bid to curb the rising use of class B mephedrone by young adults aged between 17 and 25.

Within a month seven people were arrested for possession of the drug with intent to supply.
