Police Major General Pin Amornwisaisoradej, a member of the House
of Representatives from Lampang in a special meeting on 7 January 1943:
“Taxes for opium are high while kratom is currently not being taxed.
With the increase of those taxes, people are starting to use
kratom instead and this has had a visible impact on our government’s income.”
