Officers from the Folkestone Community Policing Team attended a property in The Parade, Folkestone on Friday afternoon following reported drug deals nearby.
Inside they discovered wraps of crack cocaine and heroin, along with a quantity of cash and a knife.
Four arrests were made, two of which were later released without charge.
Ange Gode, 19, of Flimwell Close, Bromley, was charged on Saturday 4 March with two counts of possessing Class A drugs with intent to supply, possession of cannabis, and possession of criminal property.
A second 19-year-old man from London – arrested on suspicion of possessing cocaine with intent to supply – was released on bail until May 1 pending further enquiries.
Mr Gode appeared at Medway Magistrates’ Court on Friday and was remanded in custody to appear at Canterbury Crown Court on May 4.
Sergeant Greg Pochin of Folkestone CPT said: “We continue to respond robustly to reports of county line drug supply across the district, proactively disrupting their criminal activity and bringing offenders to justice.
“If you think you have seen suspicious activity in your street, perhaps a property has lots of visitors at all times of the day for example, we urge people to report it to police on 101 (999 if a crime is in progress), or via the Kent Police website.
“You can also contact the independent charity Crimestoppers anonymously by calling 0800 555111 or by using the anonymous form at Crimestoppers-uk.org”
