Kindly note:

ELECTRONIC CIGARETTES or E-CIGARETTES are ILLEGAL in Thailand.
The use of BARAKU and E-BARAKU is also declared ILLEGAL.

Do not bring them to Thailand: they are subject to criminal offenses punishable by the Thai law.

"Anyone found breaking this law by using an electronic cigarette – or vaping – in Thailand could be arrested and face jail time, or a fine several times the value of the illegal item(s). This applies both to foreigners and Thais."

The Thai police began cracking down e-cigarette and baraku movements a couple of months ago. More information on the link below:
