One serious anxiety is that the economic downturn will herald a new wave of drug misuse.The recession in the 80s coincided with the British heroin epidemic. In the US it was crack cocaine. It is not just that people turn to drugs to blot out the misery of a downturn. If the crisis pushes up unemployment, it is likely that, deprived of a legitimate way to make a living, some may turn to an illegitimate source. Perhaps a global downturn is what the drug cartels, with their huge stockpiles of heroin, have been waiting for.
