Hospital admissions for drug poisoning has more than doubled in the past decade, figures show.
However, drug-related mental health and behavioural disorders fell by nearly a quarter during the same period.
Data from the Health and Social Care Information Centre (HSCIC) shows there have been 58% more admissions to secondary care for drug poisoning in 2011/12 than in 2000/01.
Statistics on Drug Misuse: England, 2012 found there were 12,300 hospital admissions for drug poisoning in 2011/12, a 2% fall on the previous year, with 16 to 24 year olds accounting for the majority of admissions (2,900).
Drug-related mental health and behavioural disorders accounted for 6,200 admissions in 2011/12, a 7% fall on the previous year (6,600) and a 23% fall on 2000/01 (8,000), with 25 to 34 year olds accounting for the majority of admissions (2,100).
“The report brings together information from a range of sources to provide a comprehensive picture of the use and effects of drugs by people across England,” said chief executive of the HSCIC Tim Straughan.
“For drug-related admissions over the past eleven years, it shows a mixed picture with admissions increasing overall for drug poisoning while falling for drug-related mental health and behavioural disorders.”
