Thailand has some of the severe vaping laws in the world. If you‘re caught with a a vape or e-cigarette you could be fined or even go to jail for up to ten years. This is applicable to each foreigners and Thais.
The ban on the import, export, sale and possession of vaping products was introduced in 2014 by the Thai Government for health reasons which electronic cigarettes were luring teenagers into smoking.
There have been recent incidents of foreign travellers who were unaware of the ban facing an on-the-spot fine or being arrested.
Thus, travellers coming to Thailand are suggested to not bring any electronic cigarettes with them, nor any item or instrumentality related to e-cigarettes, such as, the liquid employed in the device.
