CRC/C/15/Add.180 page 13 52. In light of articles 32 to 36 of the Convention, the Committee recommends that the State party: (a) Undertake a study on the issue of trafficking and trafficking-related problems, such as sexual exploitation, drug abuse and the involvement of children in the drug trade, and economic exploitation, in order to assess their scope and causes, and develop and implement effective monitoring and other measures to prevent them; (b) Combat and eliminate child trafficking, sexual exploitation, drug abuse and trade and economic exploitation, including by developing social integration programmes; and (c) Develop and adopt a national plan of action against sexual and commercial exploitation of children, taking into account the Declaration and Agenda for Action and the Global Commitment adopted at the 1996 and 2001 World Congresses against Commercial Sexual Exploitation of Children. Administration of juvenile justice 53. The Committee reiterates its serious concern (ibid., para. 10) regarding the situation in relation to the administration of juvenile justice. While noting that under the new Penal and Penal Procedure Codes juvenile cases can be considered by specially trained judges and that there is a debate about whether to set up a separate branch for juvenile justice, it expresses its concern that a comprehensive system has not yet been established, that prosecutors and lawyers are not trained to handle juvenile cases, that detention is not used as a last resort and that alternative measures to detention are seldom applied. Further, it is noted that conditions in juvenile detention centres are very poor and offer little possibility of rehabilitation. 54. The Committee recommends that the State party: (a) Expedite the establishment of a specific system of juvenile justice, and ensure its full independence and adequate human and financial resources; (b) Continue to review laws and practices regarding the juvenile justice system in order to bring it as soon as possible into full compliance with the Convention, in particular articles 37, 40 and 39, as well as with other relevant international standards in this area, such as the United Nations Standard Minimum Rules for the Administration of Juvenile Justice (the Beijing Rules) and the United Nations Guidelines for the Prevention of Juvenile Delinquency (the Riyadh Guidelines); (c) Ensure that all persons under 18 benefit from special protection measures in the field of the administration of juvenile justice; (d) Use detention, including pre-trial detention, only as a measure of last resort, for as short a time as possible and for no longer than the period prescribed by law, and ensure that children are always separated from adults;
