Long-term effects
Cannabis is ranked one of the least harmful drugs by a study published in the UK medical journal, The Lancet.
Cannabis can be habit-forming and the development of cannabis dependence in some users has been well established; its effects on intelligence, memory, respiratory functions and the possible relationship of cannabis use to mental disorders such as schizophrenia, psychosis, depersonalization disorder and depression are still under discussion. A study published in the American Journal of Epidemiology in 2011, concluded that the prevalence of obesity is lower in cannabis users than in nonusers.
A 35-year study published August 2012 in Proceedings of the National Academy of Sciences and funded partly by NIDA and other NIH institutes provides objective evidence that, at least for adolescents, marijuana is harmful to the brain. It was found that the persistent, dependent use of marijuana before age 18 showed lasting harm to a person's intelligence, attention and memory. Quitting cannabis did not appear to reverse the loss. However, individuals who started cannabis use after the age of 18 did not show similar declines.
A July 2012 report in Brain reveals neural-connectivity impairment in some brain regions following prolonged cannabis use initiated in adolescence or young adulthood.
Абсолютно съм съгласна.
Хората се чудят как да си стимулират паметта, да не говорим за по-опасните алтернативи.
