A police blitz on drugs has removed £730,000 worth of suspected cannabis from the streets.
Nine drug factories in Halifax and Sowerby Bridge were raided and dismantled in the run-up to Christmas.
The surge of successes also saw nine people arrested on suspicion of drug trafficking offences.
All of those have been released and are currently on bail.
Inspector Colin Skeath who runs the Halifax Central Neighbourhood Policing Team said his officers had made it a Christmas to remember.
He said: “The team has worked tirelessly gathering intelligence and working with the local community to put the operation together.
“They worked closely with Special Constables and regular officers to develop intelligence on the raids.
“They have done a fantastic job.”
Inspector Skeath said the local commnity played a key role and without people coming forward to inform officers of what is happening such success would not be possible.
“Local communities should feel safe in the knowledge that if we know about something we will act,” added Insp Skeath.
“Sometimes people might not see an immediate response but that doesn’t mean we aren’t doing anything about it.
“There are different ways of tackling an issue - whether that be high visibility patrols and working with our partners or behind the scenes work to gather intelligence.”
The raids also resulted in an estimated £33,000 worth of growing equipment and plant food being seized - most were destroyed but food and pots were recycled for community groups including schools and allotment societies.
This week the US state of Colorado made history when it allowed stores to sell cannabis.
Colorado, along with Washington state, voted to legalise the use and possession of cannabis for people over the age of 21 in November 2012.
Crowds swamped stores selling the drug which is taxed in the same way as alcohol.
The Colorado branch of the National Organization for the Reform of Marijuana Laws, said the state had found an exit strategy for the failed drug war.
But critics say it sends the wrong message and fear the move will lead to serious public health and social problems.
