%X La marihuana es una sustancia psicoactiva ampliamente usada en la sociedad, especialmente entre los m芍s j車venes. El uso de esta sustancia ha sido asociado consistentemente con diversos problemas de salud, muchos de los cuales tienen en com迆n una alteraci車n en las manifestaciones cognitivas de la conducta, incluyendo la memoria, la atenci車n, la emoci車n y la toma de decisiones. Se encontr車 evidencia que los cannabinoides, la sustancia activa de la marihuana, impactan negativamente en la memoria a corto plazo, memoria de trabajo y la toma de decisiones. Asimismo, los cannabinoides afectan la atenci車n y la interacci車n entre los eventos cognitivos y la emoci車n. Esta informaci車n puede ser usada como argumento de plausibilidad biol車gica para interpretar una serie de hallazgos cl赤nicos y epidemiol車gicos en los que el uso de marihuana se ha mostrado relacionado con problemas tales como accidentes de tr芍nsito, psicosis, depresi車n, pobre trayectoria acad谷mica, entre otros. Marijuana is one of the most commonly used psychoactive substances in society, mainly among youths. Its use has been consistently associated with several health problems, many of which have in common an impairment in the cognitive processes of behavior, including the memory, attention, emotion and decision making. There is evidence suggesting that cannabinoids, marijuana∩s primary psychoactive substance, have a negative effect in short-term memory, working memory, and decision making. It has also been found that cannabinoids affect attention and the interaction between cognitive events and emotion. This information can be used as an argument of biological plausibility to assess clinical and epidemiological research findings that show that marijuana`s use is associated to problems such as traffic accidents, psychosis, depression and poor academic records, among others.
