A Japanese university professor could face up to 10 years in prison after allegedly teaching his students how to produce MDMA to "further their knowledge" of pharmaceuticals, according to reports.
Tatsunori Iwamura, 61, has been likened to Walter White, the fictional chemistry teacher in the cult TV series Breaking Bad who starts manufacturing crystal meth after being diagnosed with inoperable lung cancer.
Iwamura, a professor at Matsuyama University in Ehime prefecture, has reportedly admitted getting students in his pharmaceutical science class to make MDMA – commonly known as ecstasy – along with the "designer drug" 5F-QUPIC, in 2013.
Japanese law requires researchers to obtain a licence from regional authorities to manufacture illegal drugs for academic purposes.
The Kyodo news agency quoted unnamed sources as saying that Iwamura had a license issued by a local government outside Ehime but it had expired.
Local drug enforcement authorities believe 11 students produced the drug under Iwamura's instruction. Four students, along with an assistant professor, have also been referred to prosecutors, Kyodo said.
The university said it would discipline Iwamura and the assistant professor once the investigation had ended.
"We sincerely apologise for causing serious concern to students and their parents," said Tatsuya Mizogami, the university's president, according to Kyodo.
