HK has insane amounts of expats, significant amounts of which smoke weed. Probably almost half the expats I met, mostly rich young folks though so it's not surprising at all.
If you're white and walking around during the night you'll constantly be approached by people trying to sell you weed and coke. (Steep prices, but significantly easier to find than in most western cities)
Edit: Wrote that in a bit of a hurry. When talking about HK you need to take into account the massive income inequality between expats and many of the locals working "normal" jobs.
Weed is rather expensive for many of the locals, but for some western bankers making 10k+ USD a month it's a relatively cheap way to take a break from the rather hectic life in HK.
