INTRODUCTION Paediatric psychopharmacology involves the application of psychotropic agents to the treatment of children and adolescents with mental disorders and gathered knowledge from child and adolescent psychiatry (CAP), neurology, paediatrics and pharmacology. Defining elements of this discipline are: the metabolism of drugs is different in children than in adults (pharmacokinetics), the developing brain reacts specifically to the drug (pharmaco dynamics), and psychopathology itself is not differentiated yet. To make and overview of specifics in psychopharmacological use in CAP and emphasize some experiences from Bosnia and Herzegovina in that field. METHODS Through insight in current literature, we presented comprehensive findings and compare it with situation in Bosnia and Herzegovina. RESULTS The most common conditions in which psycho pharmaceuticals are used in CAP were attention deficit hyperactivity disorders (ADHD), depressive and bipolar disorder, obsessive compulsive disorder and the treatment of early psychosis. Psycho pharmaceuticals were also used to treat agitated conditions in various causes. We made an overview of psycho pharmaceuticals use in Bosnia and Herzegovina CAP and emphasized the fact that psycho stimulants are not approved for the use yet, although they are mostly prescribed medicament in CAP over the world. That limits us in the effectiveness of the treatment in ADHD and put us in the situations to use other medicaments instead (anxiolytics, antipsychotics, mood stabilizers) which are not approved for that condition. CONCLUSION The use of psycho pharmacotherapy in CAP is justified in cases where it is necessary to reduce the suffering of children and to improve their functionality at the time when cognitive, social and emotional advancement is most pronounced. Further research and clinical monitoring of efficacy and safety in the use of psycho pharmaceuticals in youngsters are necessary.

BACKGROUND Indian hemp (lat. Cannabis sativa subs. Indica) has been used as a source of industrial fiber, seed oil, food, medicine for some somatic diseases, and it is also used as a psychoactive substance. Cannabis can be used by smoking, evaporation, as a food ingredient, or as an extract. Acute and chronic cannabis use has been shown to be detrimental to several aspects of psychological and physical health and many experimental studies done on healthy people indicate the potential of Δ9- tetra hydro cannabinoid (THC) in inducing transient, dose-dependent psychotic symptoms, but also affective, behavioral, cognitive, neurovegetative, and psychophysical symptoms. Cannabis is the most commonly used illegal drug globally. In many communities, cannabis is perceived as a low-risk drug, leading to political lobbying to decriminalize its use. The wave of laws and initiatives to liberalize cannabis use continues to spread across the United States and the rest of the world, and there seems to be a political debate in the background about the potential risks and benefits of cannabis use. Aim is to present the possible consequences that the legalization of cannabis would have from the aspect of mental health and mental disorders. METHODS Authors reviewed the literature using PubMed resources on the effects of cannabis using the keywords: cannabis use, cannabis use and psychoticism, cannabis use and depression, cannabis use and anxiety, cannabis use and cognition, cannabis use and insomnia, legalization of cannabis. RESULTS Authors examined the effects of cannabis use on psychiatric disorders and the review of the legal status of cannabis use in the world was also made. The possible consequences of cannabis legalization on the public health system were also considered, based on experiences from countries where legalization has already been done. The evidence cited in this article suggests that strong claims about the need to legalize cannabis are still questionable, and may, even in the long run, remain mixed, inconclusive, or even contradictory. Political interference in this issue can trigger a wide range of unintended but profound and lasting consequences for the health system and the health of the individual. CONCLUSION We recommend further research on this topic and data collection with an emphasis on the effects and consequences of cannabis use on mental health, and in particular the benefits and harmful effects of medical cannabis use.

Ibn Sina (Avicenna) is primarily known for his philosophy and medicine, but there is almost no scientific discipline in which this great man didn't leave a significant mark. This paper gives a brief review of his contributions to medicine, especially to psychiatry. Medical works of Ibn Sina represent a pinnacle of most important medical achievements of his time. These works contain synthesis of all Greek, Indian and Iranian medical schools, but also new breakthroughs achieved by Muslim scholars through their own experimentation and practice. Although he wrote many medical works, his most important one is El-Kanun fit-tib, which can be translated as The Canon of Medicine. It's made out of five books which systematically show everything known in the area of medicine up until that point in time. In it, Ibn Sina discusses, among other things, the structure of psychological apparatus of human being and the connection of psychological functions with the brain as well as the role of psyche in etiology of somatic diseases. He also describes certain psychiatric diseases along with the explanation of their etiology and recommended therapy. He considered psychology to be very important for medicine, so in his psychological works he discusses, in great detail, the essence of human soul, consciousness, intellect and other psychological functions.
