""Golf.com is reporting Johnson has failed three drug tests. The site says he flunked one for marijuana in 2009 and two others for cocaine in 2012 and 2014, respectively. FOX Sports 1 golf insider Robert Lusetich reports that one of those tests was at the U.S. Open.
According to the report, he was suspended for the 2012 test but it was not made public.
Golf.com also says Johnson had had a sexual indiscretion with at least one wife of a PGA Tour player. Lusetich reports that he had such indiscretions with two PGA Tour wives, one of which ended a marriage.""
PGA won't confirm Johnson suspension. Their agreement with union on drug testing prohibits them from announcing action over drug use. Someone at PGA didn't like policy and leaked info to press. From: Tom Kelly
