LONDON (AP) – After a weekend of embarrassing tabloid headlines about her 17-year-old grandson’s experimentation with alcohol and marijuana, Queen Elizabeth II said Monday that she was pleased with the way Prince Charles had handled his son’s scrape.

“The queen shares the Prince of Wales’s views on the seriousness of Prince Harry’s behavior and supports the action which has been taken,” Buckingham Palace said in a statement. “She hopes the matter can now be considered as closed.”

Charles sent his younger son to a south London rehabilitation clinic for a day so he could talk to recovering addicts and see the dangers of drug use. Harry, then 16, admitted last summer that he’d drunk with friends at a pub near his father’s Highgrove country estate and smoked marijuana with friends, according to press reports confirmed by a royal source.

Marijuana is illegal in Britain and the drinking age is 18.

Prime Minister Tony Blair praised Charles’ actions as “absolutely right” and Peter Martin, chief of Addaction, Britain’s largest drug and alcohol treatment group, said the heir to the throne “has acted with deep sensitivity and very quickly, which is exactly what is needed.”

Harry returned to the prestigious Eton school Monday after spending Sunday at his father’s Highgrove estate. But the story of his smoking and drinking remained on front pages and at the top of news broadcasts.
