Nasal spray aimed at tackling gambling addiction to be trialled in Finland

Researchers to test fast-working spray containing naloxone, a treatment usually given to opiate addicts that blocks production of dopamine

Could gambling addiction be treated with a nasal spray? A group of Finnish researchers are launching a study to find out.

The fast-working spray contains naloxone, which is commonly used as an emergency treatment for overdoses of opiates such as heroin, opium and morphine. It blocks the production of dopamine, a neurotransmitter linked to pleasure with a central role in addictions.
