A 28-year-old woman has been charged with three counts of possession with intent to supply after around 200 bars of cannabis resin and a quantity of amphetamines and other drugs were found in a lock-up garage in Clover Way, Hedge End.
The raid took place on September 17 last year.
The bars weighed more the 20kg and all the other drugs together had a potential street value of around £250,000.
Vicki Rooke from Ivy Dene, Southampton, was arrested after the drugs were found.
She has now been charged in connection with the drugs and has been released on bail to appear before Southampton Magistrates Court on Tuesday, August 2.
