The effects of Marijuana
Marijuana can cause many harmful effects. There has never been a major test though. The ones they've used have shown very different things. I have been very surprised by what I have been reading. I cannot believe the difference in what different scientists think. One says, "It's hard to know for sure whether regular marijuana use causes cancer. But it is known that marijuana contains some of the same and sometimes even more, of the cancer-causing chemicals found in tobacco smoke. Studies show that someone who smokes five joints per week may be taking in as many cancer-causing chemicals as someone who smokes a full pack of cigarettes every day." While in certain places it is legally perscribed to people with many different types of cancer. The New scientist says, "A FRENCH government study has heaped fuel on the debate over the safety of cannabis by listing it as the least dangerous of all potentially addictive drugs. It also concludes that alcohol is among the most dangerous. The study, commissioned by French health minister Bernard Kouchner, was carried out by a panel of 10 French and foreign scientists headed by Bernard-Pierre Roques of the Rene Descartes University of Paris. The panel searched the scientific literat
" It goes on to say, "Regular heavy marijuana use compromises the ability to learn and remember information primarily by impairing the ability to focus, sustain, and shift attention, says Dr. While cautioning that no drug they assessed was "completely free of danger", the researchers gave cannabis a rating of "weak" for social hazard and addictiveness, "very weak" for general toxicity and zero for neurotoxicity. Continuing to smoke marijuana can lead to abnormal functioning of the lungs and airways. Heavy users exhibited these cognitive deficits by being less able than light users were to learn word lists; by making a greater number of errors in sorting cards by different characteristics, such as by color or shape; and by making more errors when the rules for sorting the cards were changed without warning. Deborah Yurgelun-Todd, also of McLean Hospital, tested the cognitive functioning of 65 heavy cannabis users, most of whom had smoked marijuana at least 27 out of the previous 30 days. Men in the heavy users group showed somewhat greater impairment than women in the same group. ure for information about psychological and physical dependence, neural and general toxicity and social hazards such as aggressive behavior caused by various legal and illegal drugs. It also says that while the evidence for fetal alcohol syndrome is "good", the evidence that cannabis can harm fetal development is "far from conclusive". Future research using appropriate safety measures should test the effect of higher doses of marijuana on driving as well as the combined effect of marijuana and alcohol on driving, he concluded. Heishman tested marijuana's effects on the functional components of driving. As the WHO's first report on cannabis for 15 years, the document had been eagerly awaited by doctors and specialists in drug abuse. These workers reported more absenteeism, tardiness, accidents, workers' compensation claims, and job turnover than workers who had not used marijuana. According to a document leaked to New Scientist, the analysis concludes not only that the amount of dope smoked worldwide does less harm to public health than drink and cigarettes, but that the same is likely to hold true even if people consumed dope on the same scale as these legal substances.
