New Delhi, Jan 19 (ANI): Smoking cannabis to feel less depressed is a well-known phenomenon- but does it actually work? However, a study has recently warned that the teenagers who begin smoking pot early are at an increased risk of depression and heightened feelings of negative emotionality. According to researchers, young people with cannabis-dependence have an altered brain function that may be the source of emotional disturbances and increased psychosis risk. The alterations were most pronounced in people who started using cannabis at a young age. The findings reveal potential negative long-term effects of heavy cannabis use on brain function and behaviour. Study authors Dr Peter Manza, Dardo Tomasi and Nora Volkow of the National Institute on Alcohol Abuse and Alcoholism, Bethesda, Maryland, assessed 441 young adults and compared a smaller set of 30 people who met criteria for cannabis abuse with 30 controls. People with heavy cannabis use had abnormally high connectivity in brain regions important for reward processing and habit formation.
