Please don't smoke in English (must be correct! ) urgent!

Definitely not.

smoky

If you write a no-smoking slogan in public places, it must be:

no

smoky

The reason is that grammatically,

No is an adjective, which can only modify nouns or gerunds. So you need to smoke in the back.

(that is, the gerund form of smoke)

Not is an adverb and can only modify verbs or adverbs. So there needs to be smoke behind, not smoke.
