Whatever your views are on decriminalising drugs, it's hard to think of a more reprehensible industry than the current drugs black market.

Take cocaine, for instance. Originating in South America, every gram is tainted with the blood of innocent families and children which are made to grow the Coca plant with a gun in their back. Heroin is grown in the Middle East, where it has been used to fund terrorists such as the Taliban and al-Qaeda.

Drugs are then smuggled into the UK, often by people coerced through violence, before being cut with harmful chemicals to increase the profits of the criminal gangs who sell it.

In recent years, these gangs have developed a new modus operandi: 'county lines'. Children and vulnerable adults are targeted by drug dealers to sell the product in regional areas, away from large cities like Liverpool and Manchester.

Even with cannabis, which a July 2019 poll showed 48% of Britons support legalising, the market is awash with exploitation and violence. There are numerous human trafficking and modern slavery cases which have centred on illegal cannabis farms.

While decriminalisation of softer drugs such as cannabis would wipe out the harmful black markets, in the meantime there can be no ethical consumption of illegal drugs.
