Cocaine's low point (2010)
Cocaine was involved in 144 deaths in England and Wales in 2010, a small fraction of the heroin toll at the time. Over the following 15 years the number rose more than eightfold, driven by wider availability and, according to the ONS, higher purity.
Cocaine stayed a distant second to heroin in death certificates through the 2010s.
The 2010 figure is now the reference point the ONS uses to describe how far cocaine deaths have risen.
It sets the scale: the drug that just became the leading cause of substance-specific drug deaths was a marginal contributor 15 years ago.
