Talk:smoking

Should there be an adjective sense for "designated for smoking", as in "smoking car"? Currently, the derivatives for this sense come under the noun, but is this an adjective? It can be considered as the noun used adjectivally, but this is not true of its antonym, "non-smoking". &mdash; 91.238.123.116 15:10, 10 September 2015 (UTC)
