Morgado P SCRATCH THAT!—Two case reports of scratch-card gambling disorder. Although the addictive aspects of scratchcards are described in the scientific literature, no epidemiological studies have been done in Portugal to date. However, a perception exists of an increasing number of patients seeking medical treatment for gambling problems associated with this lottery in Portugal.

Unregulated gambling produces several negative effects in society. The economics of the gambling industry (including the taxes collected by governments) might result in a lack of effective policies to regulate specific types of games. Since sales in scratchcards are increasing in the country and case reports of gambling problems associated with scratchcards are being described, further studies that address this relationship are needed to plan strategies to tackle this problem—namely, the effective regulation of sales of scratchcards. Addressing this scratch-card epidemic in Portugal is urgent and necessary. Additionally, such regulation might serve as a learning experience in mental health following the resounding success of drug policies implemented in the country since 2001.
