The use of 'snus' tobacco in English football is 'big' according to Stoke midfielder Charlie Adam.
Adam's opinion came on the day the Football Association reiterated its commitment to warning players of the dangers of legal highs amid reports of the growing use of 'snus'.
The nicotine, which comes in pouches and is ingested by placing it between the top lip and the gum, is not a banned substance, though it is illegal to buy in the United Kingdom.
England and Leicester striker Jamie Vardy admitted using the product in his autobiography and was pictured carrying it at Euro 2016.
