But the world is changing, and changing fast. Over the past decade, with an ever-quickening pace, countries have been reforming their laws to try to get a firmer grip on health, criminal justice and law-and-order issues that are rapidly escalating.

They make huge profits from selling illegal drugs and protect their “industry” with violence, using knives and guns to fight off the competition. As we have seen in London, it has been a root cause of the deaths of many young people in recent years.
