The consumption of internationally prohibited substances continues with a stable trend of five percent; However, the number of consumers has grown 30 percent in the last ten years due to the increase in the population and urbanization is a factor that contributes to the increase in their purchase. With this assertion, the Master in Psychology Raúl Martín del Campo Sánchez began his webinar, under the theme “International Guidelines for the improvement of prevention programs for substance use in young people”, within the framework of the First Symposium on Suicide Prevention and Promotion of mental health in girls, boys and adolescents, organized by PREVENFISAME. The Master, who is a member of the UN International Narcotics Control Board, affirmed that “the fact that I mention to you has been documented by the National Institute of Psychiatry, since the prevalence of consumption is much higher in the city than in the rural area ”. He warned about the damage caused to consumers by altered drugs, such as cocaine and heroin, which are combined with various chemical substances, additives or fentanyl, which is sold as if it were ecstasy; in short, they give them a hoot and they don’t know it, but it hurts them. “Currently we have identified 808 new drugs that have not been properly classified, but that shows us the speed with which the laboratories work at the service of drug trafficking. For example, in 2018 we had about 46 new drugs and if we take into account the weeks of the year, a new drug was born almost every week, ”said Raúl Martín del Campo Sánchez. One piece of information that drew attention was when he commented that due to the quarantine forced by COVID-19, there was a significant increase in the sale of drugs through social networks, with online purchases.
