MORE than 6,000 troops have been kicked out over drugs in the past eight years, The Sun on Sunday can reveal.

The last two years were the worst in a decade — with more than 1,800 failing compulsory tests.

Almost every Army regiment had soldiers who tested positive.

The worst record last year was in the Foot Guards — who protect the Queen and her palaces.

Thirty of its members failed tests, many for Class A drugs such as heroin and cocaine.

Out of 770 failures last year, the Army had 640, with some soldiers testing positive for more than one drug.

Last November, three soldiers from the Royal Armoured Corps Training Regiment were arrested over fears they were dealing ketamine.

Sources said all 300 of the unit’s members were tested after suspicions they partied over a debauched weekend.

In March this year a drugs scandal hit Prince Harry’s old regiment when four soldiers were caught snorting cocaine in a pub.

The Sun told how Household Cavalry troopers were barred from the Wetherspoons boozer in Windsor, Berks, after being rumbled.

The figures, obtained from a Freedom of Information request, also revealed the Royal Navy had 70 positive drug tests last year.

The RAF had 60.
