Q. Will I be able to smoke in theatres and cinemas?

A. Theatres and broadcasting/film studios will be no-smoking premises under the law and so it will be an offence to smoke in them. However, if for reasons of artistic integrity, it is appropriate for a performer to smoke as part of a performance, then this will be exempt.

Answer 1

Sounds OK as long as you can still blow weed.

Answer 2

Actors can be excused from smoking but the people cannot be because they are too many.
