Baxendale Drive- lived here for 20 years

osm.org/way/1198724365/history has shop = smoke_shop

Is it the same as shop=headshop - see osm.wiki/Tag:shop%3Dheadshop ? Or the same as osm.wiki/Tag:shop%3Dsmartshop ?

Or maybe it sells e-cigarettes and is shop=e-cigarette ( osm.wiki/Tag:shop%3De-cigarette )?

Or maybe shop=tobacco is the best fit ( osm.wiki/Tag:shop%3Dtobacco )?

Or is it a separate shop category that should be documented as valid?

There are three hydro electric generating stations on the NIPIGON RIVER operated by Ontario Power Generation (OPG) and they are all labelled differently. This one should be ALEXANDER FALLS GENERATING STATION. (Curiously OPG has labelled it how the locals refer to it, dropping the "falls" part.)
