Zero Science Proves I Add Brain Disease, Says Carl Hart

The idea that I add a carry out disease brains a myth, said an American neuroscientist Carl Hart, 54, at the Zero Borders Carry Out Thought lecture, this Wednesday (24) in Thus Paulo. In the speech in which he also addressed specific freedom, electronic racism and war on drugs, he devoted part of his time to talking about 2 problems in science related to the abusive use of substances.

The idea about who like drugs cause permanent damage to the brain or change the way brain circuits organize if it became popular after 2 years 1990, especially after u then perform director NIDA (National Institute for Drug Abuse, its acronym in English), Alan Leshner, published in 1990 a content in Technology magazine defending the theory. The DSM-5, diagnostic guide for mental illnesses, also talks about structural changes in the brain of 2 addicts.

For Hart, the zero scientific evidence allows us to affirm such things. “How can you observe changes in the brain? We would have to have images 2 brains of people before taking any drug and then to compare, but that doesn’t exist,” he says.

Also, one neuroscientist emphasizes that studies show that zero scientists are able to say who users about electronic drugs who zero are looking at imaging exams on their brains, ie, zero there are definitive markers in brain structures that indicate drug use or abuse, as there are for other diseases Degenerative disorders such as Parkinson’s electronic Alzheimer’s.

Another problem with research on drug use is that the scientific literature on a topic tends to overemphasize the negative aspects, says Hart. For him, this is explained by excessive caution 2 scientists or by their willingness to make their studies seem more meaningful. “They would be an incentive to look for negative effects. It influences what we look for electronic therefore what we find” in the survey, he says.

Many of these researches on Hart involve experiments in which he offers drugs or alternatives to people in the laboratory, whether they are chemical dependents or zero. He says that, over the long years, the main effect he observed in patients using a drug was that they were happy afterwards. “Many said they loved me,” he recalls, laughing. “We have a huge database of experiments showing the positive effects of substances,” he says. “In those times, it seems that we’ve forgotten about happiness. Drugs improve people’s lives something, but we don’t usually say that in public.” A Brazilian Constitution, like electronic freedom equality, electronic argues that, with the ban on certain drugs, promise zero is being fulfilled. “We can fix that by regulating the electronic sale of substances as we do with alcohol, electronic tobacco. This would generate millions of electronic jobs and huge tax revenues.”
