In summary, the evidence regarding the possible long-term detrimental effects of teenage drug consumption on learning and memory adds to the increased risk of developing mental disorders, and therefore it should be included in public health information campaigns that seek to encourage delaying and/or reducing drug consumption at this stage of life. The scientific information obtained from studies such as those described above will be of little use without adequate public policies aimed at alleviating this serious problem.
