ANSWER:

Myanmar is the world's second largest producer of opium in the world. Myanmar produces almost 25% of the total opium produced in the world.

EXPLANATION:

Opium is produced illegally in the country and also is a 'major contributor to the economy'. Opium production attracts a 'large number of farmers in the country' because of poverty and the lack of enough money to lead a sustainable life. The yield and sale of opium is much more as compared to rice and so most farmers indulge in the production of poppy from which opium is made.
