County Coroner's Office just stated ... &lt;strong&gt;Whitney Houston&lt;/strong&gt; used cocaine immediately prior to her death.&lt;br /&gt;&lt;br /&gt;Coroner Chief &lt;strong&gt;Craig Harvey&lt;/strong&gt; just held a news conference -- claiming the toxicology results suggested Whitney was a \"chronic\" cocaine user.&lt;br /&gt;&lt;br /&gt;Harvey described the cocaine level in Whitney's system as \"acute\" -- indicating Whitney used the drug not long before she accidentally drowned in a bathtub at the Beverly Hilton hotel last month. \"Accidental drowning\" is listed as Whitney's official cause of death.&lt;br /&gt;&lt;br /&gt;According to Harvey, the autopsy revealed a 60% narrowing of Whitney's arteries -- a direct result of the chronic cocaine use. Harvey claims the artery constriction led to a cardiac event before her death.&lt;br /&gt;&lt;br /&gt;As for the other drugs in her system -- marijuana, Benadryl, Flexeril, and Xanax -- which Harvey claims were all at or below therapeutic levels ... and did not significantly contribute to her death.&lt;br /&gt;&lt;br /&gt;&lt;a href=\"http://www.tmz.com/photos/2012/02/11/4346-remembering-whitney-houston\" target=\"_blank\"&gt;&lt;img alt=\"0211_rememebring_whitney\" src=\"http://ll-media.tmz.com/2012/02/11/0211-rememebring-whitney-1.jpg\" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;!-- relatedlinks --&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
