Doktore, je li istina da trava čisti pluća?

According to the information in the author's possession, "it is estimated that there are 6,000 thousand people addicted to illegal drugs and another 35,000 weekend users in Croatia." This is a large number, but still a small percentage compared to the total population of young people. The question from the title indicated the need of young people to want a lot and still have to learn about drugs and their harmful effects. That is why the author primarily addresses young people with this book and gives answers to their questions, trying to drag them away from the hell of addiction.
