A relative of mine is addicted to cough syrup. It all started when she got a really bad bout of flu. When it passed, she was left with a nasty cough, so our local doctor prescribed some cough syrup to help beat it. She took it three times a day for over three weeks. However, I noticed that she continued taking it well after her cough was cured. She had some empty bottles hidden in her drawer. When I casually brought it up, she denied it and claimed they were old ones. However, some of them looked new, like barely a day old. Does anyone here know if there's anything I could do to help?
