This problem can be resolved by handing our free khat on one day of the week preferably friday (to make the addicts more motivated to work for their prize) and ban khat sales on every other day of the week. Do this and the khat addicts will look forward to their fulfilling their needs at the end of a hard working week and will savour the feeling even more. It's operant conditioning and would work well on geeljires since without an education their iq is equal to that of a child or dog.
