They also blocked social media pages which encouraged the use of drugs.
RAK Police close down 22 drug promoting websites
Twenty-two websites have been shut down since January by Ras Al Khaimah Police for promoting drugs.
Police e-patrols tracked down and closed the sites which were found to be advertising and selling illegal substances to young people, said Col Adnan Al Zaabi, head of anti-narcotics police.
He said the websites facilitated drug consumption and tempted young people into taking drugs by showing them different methods of ingestion.
The e-patrols team also blocked a number of similar social media pages - operated outside of the UAE — through the Telecommunications Regulatory Authority (TRA).
RAK police said they will continue to vigilantly monitor the internet and urged the public to report such websites to them.
