I doser 

Idoser is an old drug that young people use, mostly in the states. Its only needed an I doser song, a dark room an a pair of good headphones to get high. It uses frequencies that are known to generate different changes in the brain alternating all the signals and making the consumer experience weird trips. This may vary depending on the song, many of them can generate a bad trip intentionally, making the person feel angry, extreme fear and many other bad feelings. Others can generate pleasure and even get to induce an orgasm. And many others can generate a state of relax. The whole I doser proyect is thought for selling the songs on the internet and has existed for long time, only that distributing this songs was a lot harder in the past. Its really important that the person can eliminate all external factors and focus only in the song to get high. There are also boosters that come in pills and are meant to make the trip a lot better and lot more intense.
