The aim of our project called „Let’s stop drugs” is to implement a double youth exchange in Cristuru Secuiesc and Velyka Byihan between 16-24 year old young people (from whom 16 disadvantaged) of 4 countries. During the twice 9 day long youth exchanges implemented as a bottom-up initiative we want to focus on the one hand on the development of the youth’s knowledge in connection wtih drugs so that they learn such mechanisms that help them ward off emergency in connection with drugs and a preventive view should be formed in them. On the other hand our aim is that they learn knowledge and abilities through which they can identify the appearance of drugs in their surroundings, help the young people who got in contact with drugs and can transmit them the preventive view. By reaching these goals we contribute to the decrease of drug use of young people, the increase of youth communities, peer groups in this respect in the long run too. The programme draws attention to a quite serious problem and we want to emphasize with our program the lack of space of the drug prevention work: the importance of learning from each other and peer help. The main aim of the thematic work planned on the youth exchanges is to make the young people understand what are the reasons inside us that make somebody be dependent. Over the understanding of the reasons to get the information, abilities that help the emergence of drug use, and/or what we can do if we need help or somebody in our surroundings needs help. Over the understanding the social reasons the aim is the understanding of ourselves, our motives,since it helps a young person very little if he understands what socially leads to the drug use. Through this only his intellect got impulse and he can get it from anywhere, from books and the internet.
