Nasal spray helps break betting habit.

GAMBLING addicts may soon be able to treat their "craving" to place a bet with a nasal spray.
Finnish researchers are conducting a study to find out if naloxone, commonly used to treat heroin, opium and morphine addiction, could help gamblers.
The spray blocks the production of dopamine, a chemical linked with pleasure, and could stop the rush gambling addicts experience from betting.
A version taken as a pill failed because the drug took one hour to be absorbed into the system.
Hanna Alho, a professor of addiction medicine, said: "The need to gamble starts right away.
"We are seeking a medication with a quick effect. The nasal spray acts in just a few minutes."
