Researchers have identified a factor that may contribute towards the development of heroin addiction by manipulating the adenosine A2A receptor, which plays a major role in the brain's 'reward pathway.' Using mice specifically bred without the adenosine A2A receptor, scientists showed that these mice had a reduced desire to self-administer morphine; heroin is converted to morphine in the body.
