I do use drugs. I have never seen spirits in a plastic bottle, even own brand super market vodka.

Boxed wine exists, and is a bit under half the market (by volume). Wine in glasses is still the majority of sales. Beer/cider/larger is sold in cans or bottles, with cans being about 2/3rd by volume.

I do drugs as well, but I don't typically drink alcohol. Maybe I am not qualified to speak on this, but in the US most of the cheap vodkas have been coming in plastic bottles for around 15 years now at least.
