Marijuana seems to be on an unstoppable march to legalisation in the United States. New York and New Jersey are racing to join the 10 states that already allow recreational use of cannabis. Some 65 per cent of Americans favour legalisation, and several potential Democratic candidates for president support ending federal prohibitions on marijuana.
This huge shift in public attitudes comes even though most Americans do not use the drug. Only 15 per cent of people over 12 used it even once in 2017, according to a large federal survey. That year, only 3 million people tried it for the first time.
