It's the first human study to show that smoking cigarettes stimulates the brain 's production of chemicals called opioids. The opioids are known to play a role in soothing pain, increasing positive emotions, and creating a sense of reward. Both morphine and heroin trigger this same chemical flow. The new study also confirms previous findings -- from animal studies -- that smoking cigarettes affects the flow of another feel-good brain chemical called dopamine. Researchers are now investigating the interaction between the two chemicals in the brains of smokers and nonsmokers.
