'Storm Chasers' Star Joel Taylor's Cruise Ship Had Zero Tolerance Drug Policy

EXCLUSIVE

The cruise line on which "Storm Chasers" star Joel Taylor died of an apparent OD this week does not allow illegal drugs on the boat ... which raises the question -- how did they ignore a river of drugs on board?

Royal Caribbean International tells TMZ they have a "zero tolerance" policy when it comes to drugs. If the crew finds them, they confiscate them.

So the question ... multiple passengers tell us drug use was out in the open ... flagrant and notorious.  The parties were drug-fueled and, as we reported, Taylor was so out of it he fell into unconsciousness on the dance floor and had to be carried to his room after allegedly consuming GHB. 

As we reported ... we're told several passengers suspected of drug possession were stopped after drug-sniffing dogs zeroed in on them at the Ft. Lauderdale port where the ship departed.

TMZ broke the story ... the FBI is now investigating Taylor's death and has already spoken to folks at the cruise line to find out what went down on board.
