Is there a type of music that can have the same effect on you as drugs? Apparently so. I-Doser, a kind of audio sound which creates the feeling of drug taking, has recently become popular on the internet. However, experts suggest people don't rush out to try I-Doser in a hurry.

"I feel very comfortable after listening to the I-Doser and can't help trying it many times throughout the day." Mr. Chen, from southeast China's city of Fuzhou, told the reporter from the Southeast Express.

Chen added that it was such a strange and addictive feeling that he would feel very uneasy if he didn't listen to it several times a day. "I am afraid of it. Maybe I have become addicted to it and the feeling is just like taking drugs." Chen said.

Nevertheless, most of Chen's friends thought that they became increasingly upset after listening to it more than once.

The reporter also gave I-Doser a trial listen after downloading an I-Doser 'preview' from the internet. However, during the four minutes in which the program ran, the reporter failed to concentrate when hearing the irregular music and was made uneasy by the quirky laughter at the end of the audio. The reporter experienced similar uneasy feelings after dabbling with other I-Dosers.

Lin Rongfa, a professor at the Fujian University of Traditional Chinese Medicine in Fuzhou, notes that the I-Doser is similar to hypnosis, affecting the human nerve system and emotional response. It is easy for those who have strong self-awareness and a sensitive disposition to accept this kind of music through which they can relieve their irregular feelings.

Lin emphasized that there was no doubt the I-Doser is without scientific foundation and only a few people feel comfortable after listening to it. Therefore, he warns that people should not try it if they wish to avoid being adversely affected.

Lawyer Jiang Dianhui, believes I-Doser will have a negative impact on listeners. However, it can't be regulated at present since there is not yet a legal mechanism to determine its legality.
