Investigative sources say Japanese actress Erika Sawajiri has admitted using other illegal drugs as well as MDMA for a long time.
Sawajiri was arrested on Saturday on suspicion of possessing the synthetic drug MDMA at her apartment in Tokyo. She reportedly told police she used the drug.
Police reportedly heard seven years ago from a person close to Sawajiri that she had been taking illegal drugs.
Police suspect Sawajiri may have habitually used illicit drugs, and are looking into when she began to use them.
