E/C.12/NAM/CO/1 with regard to sterilization, as recommended by the Committee on the Elimination of Discrimination against Women; and (d) raise awareness among medical personnel of that requirement. In that regard, the Committee refers the State party to its general comment No. 22 (2016) on the right to sexual and reproductive health. Substance abuse 69. The Committee expresses concern at the significant prevalence of alcohol consumption and drug use among school-aged children (art. 12). 70. The Committee urges the State party to take measures for the prevention of substance abuse among children and to provide children concerned with access to treatment for alcohol and drug addiction. Right to education 71. The Committee notes that, in spite of near-universal enrolment at the primary level of education, some individuals belonging to certain groups, such as indigenous peoples and those living in rural and remote areas, still do not have access to education. Moreover, the Committee also notes with concern that the capacity of schools, including for early childhood education, has not followed pace with the increased enrolment. Moreover, the Committee also notes with concern the relatively high rate of school dropout. The Committee is further concerned that the system of voluntary contributions by parents may perpetuate or even aggravate inequality in access to quality education, as those schools in more affluent areas will be able raise more resources (arts. 13 and 14). 72. The Committee recommends that particular attention and resources continue to be devoted to those who do not enjoy their right to education, including early childhood education, in spite of the focus of the State party’s education policy on developing a high-quality education system. In that regard, the Committee recommends that the State party continue to develop the school feeding and the satellite and mobile schools programmes and to monitor their impact on the enjoyment of the right to education of the most marginalized groups. The Committee also recommends that the State party address the root causes of school dropout. Furthermore, it recommends that the State party allocate resources to ensure equal access to quality education. The Committee refers the State party to its general comment No. 13 (1999) on the right to education. Cultural rights 73. While noting the State party’s plan to introduce teaching in children’s home language, the Committee regrets the lack of information on other measures taken to promote the cultural rights of the groups contributing to the State party’s cultural diversity, especially in the light of reports of discriminatory attitudes towards children from certain groups (art. 15). 74. The Committee recommends that the State party: (a) promote the culture of the various groups that make up its population, including by teaching their histories and culture in school; (b) promote the preservation of the traditional way of life of the various ethnic and language groups; (c) combat prejudice and eliminate discrimination; and (d) provide not only teaching in children’s home language but also curricula and school environments that are culturally appropriate. The Committee refers the State party to its general comment No. 21 (2009) on the right of everyone to take part in cultural life. 12
