The Rational Choices of Crack Addicts
...Drug warriors may be skeptical of his work, but some other scientists are impressed. “Carl’s overall argument is persuasive and driven by the data,” said Craig R. Rush, a psychologist at the University of Kentucky who studies stimulant abuse. “He’s not saying that drug abuse isn’t harmful, but he’s showing that drugs don’t turn people into lunatics. They can stop using drugs when provided with alternative reinforcers.”
A similar assessment comes from Dr. David Nutt, a British expert on drug abuse. “I have a great deal of sympathy with Carl’s views,” said Dr. Nutt, a professor of neuropsychopharmacology at Imperial College London. “Addiction always has a social element, and this is magnified in societies with little in the way of work or other ways to find fulfillment.”
So why do we keep focusing so much on specific drugs? One reason is convenience: It’s much simpler for politicians and journalists to focus on the evils of a drug than to grapple with the underlying social problems. But Dr. Hart also puts some of the blame on scientists.
“Eighty to 90 percent of people are not negatively affected by drugs, but in the scientific literature nearly 100 percent of the reports are negative,” Dr. Hart said. “There’s a skewed focus on pathology. We scientists know that we get more money if we keep telling Congress that we’re solving this terrible problem. We’ve played a less than honorable role in the war on drugs.”
