In Scotland pubs can ban vaping if they want. Among the Edinburgh-area pubs I go to, it's banned in Sandy Bells, the Antiquary, the Gait and the Dean in Newtongrange; allowed in the Captains Bar; and the Goth in Prestonpans seems to allow only the less fumy ones.

Bummer because the Captains is my favourite, but I can't face an evening being teargassed.
