or:\u201cIn a world first,\u201d reports The Sydney Morning Herald of Australia, \u201cSydney researchers have demonstrated what many people have long suspected\u2014that memory loss and lack of concentration caused by smoking marijuana persists long after people stop using the drug.\u201d The research, conducted at Macquarie University, confirmed that the damage marijuana causes is proportional to the amount smoked and the duration of the practice. The news gets worse: \u201cThese impairments may not be reversible.\u201d The study showed that former users suffered the same \u201ccognitive impairments\u201d as those who still smoked marijuana. More than memory is affected, especially for those who have used the drug for five years or more. Such individuals were found to be slower in processing information and less able to focus their attention and avoid distractions. The report concludes that, according to the combined evidence, smoking marijuana actually changes the brain\u2019s physiology.
