KIRSTIE ALLEY - ALLEY, PRESTON AND TRAVOLTA JOIN CRUISE'S ANTI-DRUG CRUSADE

KIRSTIE ALLEY, KELLY PRESTON and JOHN TRAVOLTA have joined TOM CRUISE's controversial battle against anti-depressants - by launching a public drive to restrict the use of medicines they believe cause suicide and violence among users.

Alley, Cruise, Preston and her husband Travolta are long-term followers of L RON HUBBARD's Church Of Scientology, which has been labelled a "cult" by some critics.

And Cruise recently angered the American Psychiatric Association (APA) by attacking the use of anti-depressants, because the controversial faith teaches that drugs and psychiatry are destructive and dangerous.

But Alley, Preston and Travolta have leapt to the WAR OF THE WORLDS hunk's defence, by joining a group of doctors who are pushing for American authorities to put tougher warnings on prescription medication about their possible side-effects.

Alley and Preston wrote an open letter to the Food and Drug Administration, which reads, "We can no longer sit back and let the clock tick, waiting for more deaths, suicides or people driven to violent acts by psychotropic drugs."

Alley explains, "Parents in particular have been misled about the effects of these drugs. They are highly addictive; kids are using them more than street drugs to get high."

Preston adds, "Parents don't know that these drugs are turning kids into walking time bombs. Eight out of the last 13 school shooters were taking prescribed psychiatric drugs, and only now is the FDA investigating the fact these drugs can cause violence."
