THAI authorities will burn $320 million worth of drugs next week in an annual narcotics bonfire to mark anti-drugs day.
A torch will be put to more than four tonnes of seized substances with an estimated street value of 10 billion baht on June 26, the United Nations day against drug use and trafficking.
"This is to demonstrate the determination of the Thai government to eradicate drugs from Thailand," the ministry said in a statement.
Illegal substances going up in flames this year - Thailand's 36th drugs burn - include 32 million tablets of methamphetamine, 1.1 tonnes of heroin, 7.2 kilograms (15.8 pounds) of ecstasy and 2.2 kilograms of cocaine.
Thailand's new government in April re-launched the controversial "war on drugs" championed by ousted prime minister Thaksin Shinawatra.
They said there would be no extra-judicial killings which rights groups say plagued a similar 2003 anti-narcotics push, but the interior minister has warned: "If anyone does not want to die, don't walk this road."
