Abstract(s)
Esta dissertação aborda as implicações do uso de canábis na saúde mental, a partir da identificação destes efeitos tal como são reportados pela literatura científica. Para isso, foi utilizado o método de revisão scoping da literatura, que envolveu uma pesquisa sistemática de artigos publicados entre 2020 e 2023, resultando em N=42 estudos. Os principais resultados indicam uma associação significativa entre o uso de canábis e o aumento de psicopatologia, como ansiedade, depressão e psicose. O uso diário de canábis está ligado ao aumento de sintomatologia, como psicose, stress pós-traumático e ideação suicida, enquanto o uso mensal ou anual está associado a efeitos adversos reduzidos. A potência da canábis, nomeadamente de tetrahidrocanabinol (THC), correlaciona-se com efeitos negativos acentuados na saúde mental. Em contrapartida, uma maior proporção de canabidiol (CBD) correlaciona-se com uma diminuição da sintomatologia ansiosa. As conclusões manifestam a necessidade de uma regulação informada sobre o uso de canábis, enfatizando estratégias de prevenção e intervenção para mitigar riscos, especialmente entre populações vulneráveis. A pesquisa científica posterior deverá considerar uma descrição detalhada da canábis, pois a distinção entre os seus compostos e as suas modalidades de uso é essencial para entender os seus efeitos na saúde mental.
This dissertation addresses the implications of cannabis use on mental health by identifying these effects as reported in the scientific literature. To this end, the scoping review method was employed, involving a systematic search of articles published between 2020 and 2023, resulting in N=42 studies. The main findings indicate a significant association between cannabis use and an increase in psychopathology, such as anxiety, depression, and psychosis. Daily cannabis use is linked to increased symptoms, such as psychosis, post-traumatic stress, and suicidal ideation, while monthly or annual use is associated with reduced adverse effects. The potency of cannabis, particularly tetrahydrocannabinol (THC), correlates with more pronounced negative effects on mental health. Conversely, a higher proportion of cannabidiol (CBD) correlates with a decrease in anxiety symptoms. The conclusions highlight the need for informed regulation of cannabis use, emphasizing prevention and intervention strategies to mitigate risks, especially among vulnerable populations. Future scientific research should consider a detailed description of cannabis, as distinguishing between its compounds and modes of use is essential for understanding its effects on mental health.
