Over the last 3 years, 25,000 contacts to the NSPCC helpline raised concerns of substance abuse near children.
The number of contacts has increased by 16 per cent since 2013/14, with 8,500 people from across the UK contacting us last year.
It's an average of almost 1 contact every hour focusing on drugs and alcohol.
Some contacts have been judged so serious that we've made more than 20,000 referrals to external agencies, including the police and children's services.
