Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

The number of prisoners taking hard drugs, particularly heroin, has increased by 80 per cent since mandatory testing began in jails, research suggests. The new Home Office figures, published yesterday in the British Medical Journal, provide the first evidence to support claims that inmates are switching from cannabis to hard drugs in an attempt to beat checks on drug taking. Inmates are reportedly changing their drug habits because cannabis can be detected in the blood for up to three week compared to heroin and cocaine which remains for about three days.

The Prison Service has set up an inquiry to establish whether the switch is taking place following the introduction of mandatory testing in all jails in England and Wales. A spokeswoman said yesterday that there was no evidence available yet to support the claims by prison officers, inmates and inspectors.
