At least 12,000 e-cigarettes, worth about 3.6 million baht, have been seized during raids on five shops near schools in Bangkok.

Consumer protection officials searched three shops on Soi Ratchadaphisek in Chatuchak district, one in Soi Lat Phrao 122 of Wang Thong Lang district and another in Soi Ramkhamhaeng 65, Wang Thong Lang, on Tuesday night.

Twenty bags containing more than 12,000 e-cigarettes in total were seized, a PM office minister told reporters on Wednesday. They had a retail value of 3.6 million baht.

She said e-cigarette products sold near schools were packaged to appear like snacks, ordinary pens or even small milk cartons to increase their appeal to young people. With such packaging, teachers were not aware that vaping pens were being sold nearby.

The nicotine in e-cigarettes was a dangerous substance that could damage the brain and affect development until around the age of 25 years. It affected emotions and the ability to learn and increased the risk of addiction to other types of drugs, the minister said.

The raids followed Prime Minister Srettha Thavisin's instructions during a cabinet meeting that state agencies should step up efforts to stop the smuggling and sale of e-cigarettes, particularly in shops near schools.

Shop employees arrested during the raids were all from neighbouring countries.
