Police and councillors have fallen ill after using the vapes, with police launching an investigation.
It comes on the eve of school half-term in Hampshire, where a senior police officer has pleaded with parents to warn their children.
Hampshire police said both teens have since recovered, but the incidents, which happened in Eastleigh, have raised serious concerns about the dangers of unlicensed and untested vapes.
Chief Inspector Rachel Noble, district commander for Eastleigh, said: “I am, of course, very concerned that teenagers in our community have become unwell following the reported use of a vape.
“We are continuing to investigate the reports, and our enquiries are ongoing to establish the full circumstances surrounding these incidents.
“We hope that increasing information and education on the dangers of possessing vapes of unknown and unlicensed origin will make those who use them think twice about doing so.”
Eastleigh Borough Councillor Rupert Kyrle emphasised the risks that vapes can pose to young people.
Cllr Kyrle said: “It’s awful to hear about these young people becoming unwell, it must’ve been very distressing to their families.
“People need to be aware of what they are buying, clearly some of these products are illegal and very harmful.”
The Botley ward councillor raised concerns about the marketing used to sell vapes, stressing the packaging is “clearly aimed at young people”.
He added: “Packaging needs to be addressed. There should be very clear warnings all over.
“Packaging needs to be dulled, and perhaps steps should be taken to put them behind screens.
“Vapes are currently front and centre with flavours that appeal to young people.”
Officers say they will continue to work with colleges, schools, pupils, teachers, and parents, delivering assemblies and talks as needed.
Students will be informed about the laws surrounding vapes, including that it is illegal to purchase them on behalf of anyone under 18.
They will also be advised that vapes should contain no more than 2ml of liquid and the nicotine strength must not exceed 20mg/ml.

Ch Insp Noble added: “To parents and guardians of young people in our area, we ask that you please continue to reinforce and share the above information and messaging with your children.
“This will help to ensure no other children become unwell as a result of vapes, including those which are unlicensed and untested.”
