Sunderland have banned away fans from bringing coins and vapes into the Stadium of Light.
The new measures have been introduced after an increase in disorder this season, including Championship matches at home to Coventry City and Burnley.
All away supporters will now be searched before entering the ground and anyone found possessing these items will be asked to discard them.
The changes will come into effect this Saturday at home to Cardiff City.
Away supporters at the Stadium of Light are currently housed in the upper tier of the North Stand, although Sunderland said they would consider moving them.
