How strict are customs in Kabul Airport?

I’m British-Afghan and I’m going to Afghanistan soon for a family wedding. My cousins there have been begging me to bring them some alcohol from the UK. (Yes I know).

I was wondering about the practical reality of sneaking it in. Suppose someone tried bringing some disguised as an ordinary household product, like putting it in a water bottle, perfume bottle, or skincare bottle. If customs saw it, what would realistically happen?

Very odd question I know, but any helpful response would be appreciated! 🙏
