The growing trend of heroin has been started since last year and there is an
increase of heroin producers and independent retailed traffickers in Thailand, ThiaMyanmar,
and Thai-Lao PDR borderline. Heroin was smuggled through Mae Sai
District, Mae Fah Luang District; Chiang Rai Province, and Pai District; Mae Hong
Son Province. Besides, the availability and the lower price of heroin indicated that
the epidemic problem of heroin is going to return in our society in the near future.
