The document describes a behavior modification project where a man from Qatar gave his wife the money he would have spent on qat (a plant with stimulant properties) each month. If he was able to avoid qat for two months, his wife rewarded him with a new cell phone at the end as motivation to stay away from qat. The project was a success as he was able to modify his behavior and stop using qat with the incentive of the financial reward from his wife.
