The study found that the average age of drug use initiation was 19 years and that abuse is highest among men and youth. Recommendations include the introduction of a selective drug prevention policy focusing on young people at universities and work environments. Increased abuse of synthetic drugs is a concern in South American countries such as Colombia, where they negatively affect local communities. The drugs are distributed in small quantities and may have their quality altered in mixtures that may be particularly harmful. Another trend observed in the country is the decrease in the average age of the users of such drugs. Small-scale trafficking in Colombia, commonly referred to as “microtrafficking” has become a growing problem in several Colombian cities.
