TWO Assembly committees are set to discuss whether smoking should be allowed on film sets.
The proposed amendment from the Welsh Government would make artists and performers exempt from the current smoke- free regulations if the integrity of the performance justified it.
The exemption would only apply if no children or members of the public were present.
The Enterprise and Business Committee and the Health and Social Care Committee have each set up a sub-committee to study the evidence together.
"On the one hand we will be examining whether there is a commercial need for this amendment and whether it will achieve its aim of supporting the creative industries in Wales," said AM Nick Ramsay, chairman of the enterprise and business committee.
"But this commercial need must be balanced against issues such as offering adequate protection to others," added Mark Drakeford, chairman of the health and social care committee.
