Since we're referencing science articles, I have two: "... researchers have concluded that neurocognitive changes that can be reasonably attributed to chronic cannabis use are subtle compared, for example, with those seen in neurological illness, and depend on prolonged and quite heavy levels of consumption." (Rogers and Robbins, 2001) "Some cognitive deficits appear detectable at least 7 days after heavy cannabis use but appear reversible and related to recent cannabis exposure rather than irreversible and related to cumulative lifetime use." (Pope, et al., 2001) Sources: http://research.lycaeum.org/researchpdfs/2001_rogers_1.pdf http://research.lycaeum.org/researchpdfs/2001_rogers_1.pdf http://www.cannatrade.com/pdfdocuments/new/NeuropsychologicalPerformance.pdf http://www.cannatrade.com/pdfdocuments/new/Neuropsychologica...
