My diabetic brother is staying in Bangkok for a few months and wants my son, aged 25, to take him a pot of diabetic testing strips from the UK when my son travels to Bangkok later in June. (My brother can't get the type of strips needed to fit his little machine in Thailand).
I am nervous about my son taking " medication" for someone else into Thailand. Will he have difficulty with Customs checks at Bangkok airport?
all views will be appreciated.
