LAGS are cooking up new strains of zombie drug Spice 20 times stronger than the regular type.

A prison report revealed the Breaking Bad-style operation is taking place in a secret lab behind bars.

And jail chiefs are now scrambling to shut it down before the new crystal form of the drug wreaks havoc.

Spice, which can contain rat poison and solvents like glue, paint and cleaning fluids, is often smoked in a joint, cannabis-style.
