As a matterfact i actually started Vaping here in LOS just recently,i life here since 4 years now. The guys in the forum mentioned above are very helpfull and help each other out. You can find many informations there. If you do order from on of the many Thai online shops you get your stuff Max. 2 days later,credit to the Thai post service wich is realy super fast.Coistomer service in english is most of the time possible and most pf the vendors are very freindly.
To get supplies here is no problem at all exept of good juice. Chines juice is chep but you get what you pay for but if you oreder ahade and wait 2 weeks, parcels labeld as presents with low value ond the juice labeled as food flovoring will find it's way to you from anywere in the world.I the case coustoms open the pack it could be possible that you will need to pay a fee wich is most of the time affordable and worth to pay.
Well,if Vaing is illegal herer in the KINGDOM,i don't know but keep it on a low provile and everything will be fine.Vaping in public is so far no problem at all.Just don't do it in plces were smoking is prohibited and don't try to be a smart as by saying,but i am not smoking.Firt if you offend a Thai by VAPING only a few know the diverance and second he might not care what you hafe to say anyhow.As everything here,let the Thais be the Thais and you are the guest than you can have a joyfull and good life in the KINGDOM.
Well,good luck with your plans and happy VAPING.
