These [legal highs] are made in a lab. They're extracting the purest form of the substance.
– David Bremner, associate medical director, CRI
One of the UK's biggest drug and alcohol charities, CRI (Crime Reduction Initiatives) has warned that the UK is seriously underestimating the dangers of so-called legal highs and how many people are using them.
The organisation says the situation is urgent and new drugs are being developed every week with very little known about what's in them, some are thought to be 10,000 times stronger than illegal street drugs.
