With more young people vaping and schools at a loss how to prevent it, the NSW government will host a panel of experts and interest groups to help guide policy measures.

The state's first Vaping Roundtable will bring together principals, students, health officials and other stakeholders to discuss the tricky issue on November 16.

After hearing evidence how vaping is affecting young people and schools, the group will discuss effective school-based interventions

Education Minister Prue Car said many schools were struggling to find answers in the face of rampant vaping by students.

The government was committed to taking an evidence-based approach.

"It is important we take on board what we are hearing form health experts and we listen to what our teachers and principals are telling us," Ms Car said.

Premier Chris Minns said evidence suggested vaping was a pathway to increased smoking rates in young people, an issue the government was committed to addressing.

"This is a way to hear directly from schools, health experts and other key stakeholders on how we can begin to address this serious health issue in our schools," he said.

Those invited to the roundtable include Chief Health Officer Kerry Chant, Manager of the Cancer Council NSW's Tobacco Control Unit Alecia Brooks and University of Sydney School of Public Health Associate Professor Becky Freeman.

Also attending will be leaders from the NSW Department of Education, NSW Teachers Federation, NSW P&C Federation and the NSW Advocate for Children and Young People.

Last month, the government committed $6.8 million over three years to clamp down on illegal vape-vendors, many who openly flaunt laws banning the sale of nicotine-based products without a prescription.

More inspections would be carried out of outlaw vape-sellers but a national ban would be key to stamping out the practice across all retail settings, Mr Minns said.

The federal government in May announced $234 million for tougher regulation, including stricter import and packaging controls.

The measures will include banning the import of non-prescription vapes for retail settings and of single-use products.
