DO you know whats inside these ?

Tried a Google, this thread comes up as results 1 & 2

Never heard of the things, what are they supposed to do?

I was offered some of them in a disco.

Some lady said they make the brain go faster, so I was afraid its some kind of a drug.

The pills looked like small silver bullets 1mm size.

Later that I fell asleep and waked up missing 1500 dollars, but thats another story

Maybe the name was JINTAN.

Google has results for this name.

If you are talking about the normally JINTAN thatz they always hv inside Pharmacy shop . They are 2 different kind of them one is JINTAN WHITE and One is JINTAN RED.. But both of them are typical Thai lozenges thatz basicly made from herbs to help you about sore throat.

15 baht per pack.
