On my last trip 4 yrs ago, we were approached whilst sitting outside in cafe's, buy a several different guys who would produce a small bottle (simialar to a cough medicne bottle) with a clear liquid in it, and what looked like a few leaves.... On every occasion they would just come up to us and show the bottle, no conversation etc!! We just said No thanks, and he/they would leave.
Im guessing that this was some kind of drug??? Can anyone confirm this more???
Thanks!!! :)
