Medical Marijuana and Civil Liberties Research Project
In the case of chronic, long-term marijuana use, several studies indicate that “heavy users displayed significantly greater impairment than light users on attentional/executive functions, as evidenced particularly by greater perseverations on card sorting and reduced learning of word lists.”4 Even so, doubts remain as to the true cause of these perceived impairments, and despite the fact that “heavy marijuana use is associated with residual neuropsychological effects even after a day of supervised abstinence from the drug … the question remains open as to whether this impairment is due to a residue of drug in the brain, a withdrawal effect from the drug, or a frank neurotoxic effect of the drug.”5 When the totality of statistical and scientific data is objectively considered, it becomes quite clear that “the weight of evidence suggests that long term heavy use of cannabis does not produce severe impairment of cognitive function like that observed in heavy alcohol users … (and) there is evidence that it may produce more subtle cognitive impairment in the higher cognitive functions of memory, attention and organization and integration of complex information.”6
Global Warming Realities Project That There Will Be Fewer Coal Burning Plants
The science associated with global climate change points the finger at the burning of fossil fuel as a major cause for warming of the planet. Hence, an alternative must be found in time to replace coal, and the question in this paper was, is nuclear power the appropriate replacement for coal-fired plants? The answer has to be "no" because first of all the economics of building new plants makes them too expensive in a time of budget cuts and tight budgets; secondly the record of plant safety in the U.S. does not lend itself to public confidence in the technology.
