From what I have seen, most of the drugs in Thailand are tablets,

which do not cause HIV infections???

Astral--good point, I was wondering about that myself. I've always steered clear of the drug crowd, but what exposure I've seen--including living in an area where drugs were used some years back--it seemed that most everything was smoked or in pill form.

I would be interested in finding out how many IV drug users there are in the Kingdom and what they are using. These drugs are pretty expensive for the average person, I would think.
