My wife does shisha and I hate it; she says it calms her down - please advise?

So the first thing, shisha is equivalent to smoking over 100 cigarettes. In one session of shisha, that is the recommendation, the research by the British Heart Foundation. So what does this mean? It means that it's going to be harmful to your body. Now maybe she's not aware of this, so that's the first thing to do is to explain that, look, it's something harmful to your body, something we shouldn't be doing at all in any way, shape or form. Number one. Number two is to acknowledge, yes, there are certain times where we're stressed, you know, with the pace of life, that you need sometimes some avenues in order to feel calm, to feel relaxed. However, we need to channel these. So acknowledge, yes, that we all need these aspects, but how is it that we can look at and explore together avenues that you can do ideally together, to help relax together, to help be calm together, or if not, then individually. And that's what I would do. So number one, explain that it's haram. Number two, then acknowledge as well her feelings and use different avenues in order to facilitate this and help.
