This is the story of Britain's biggest ever drugs bust. 'Listen, Leaf,' Pritchard said, 'the hash is neither here nor there. You'r in a lot more trouble than possession of a bit of dope.

Operation Julie in 1977 remains Britain's biggest ever drugs bust. The work of eleven police forces, it resulted in the break-up of one of the largest LSD co-operatives in the world, the arrest of 120 people and, according to reports, the seizure of six million trips' worth of LSD crystal, valued at GBP 100 million. Overnight, the price of a tab went from GBP 1 to GBP 5. This is the first insider account of how it felt to be caught up in - and by - Operation Julie.
