Whitney Houston's mother is "devastated" and "inconsolable" over the L.A. County Coroner's Autopsy Report that makes it clear ... Whitney was deep into cocaine when she died.

Cissy Houston is telling close friends ... she cried hysterically when she first heard about the Coroner's findings -- that white powder (which we know tested positive for cocaine), a drug spoon and other trappings of drug use were found in the hotel room. 

Cissy says her biggest fear is that people will now remember her daughter as a druggie, and not a talented singer and family woman.

Cissy singled out Whitney's performance of the National Anthem at the 1991 Super Bowl, saying, "This is the type of thing people should remember Whitney for."

Cissy added, "No one's perfect. Only the Lord can judge."

A "spoon with a white crystal-like substance on it" and a "white powdery substance" -- which we know was later tested and determined to be cocaine -- was found in the hotel room where Whitney Houston died ... this according to the singer's final autopsy report.

The report, which gives a detailed description of Whitney's room when officials arrived, says "Located on the south portion of the counter was a small spoon with a white crystal-like substance in it and a rolled up piece of white paper, along with other miscellaneous items."

"Located in the top drawer, in the north side of the counter were remnants of a white powdery substance, and a portable mirror on a base." Officials found more white powder on the base of the mirror.

The report also states, "[Whitney] possibly overdosed on a narcotic substance, prescription medications, over the counter medications and alcohol."

According to the report, Whitney's body was discovered FACE DOWN in the bath tub ... with a "bloody purge coming from her nose." Officials say there were no signs of foul play.

The report notes Whitney had a history of substance abuse ... which was evident by a "perforation of posterior nasal septum."

The singer's official cause of death is listed as accidental drowning -- but heart disease and "chronic" cocaine use were contributing factors.

The report notes ... when officials discovered the body, Whitney was wearing a brown wig "tightly attached to the hair."

As TMZ previously reported, Whitney had cocaine in her system at the time of her death -- which tests showed she used immediately prior to her death.

Officials say Houston also had traces of marijuana in her system ... as well as Xanax (anxiety medication), Flexeril (muscle relaxer) and Benadryl (allergy medication).

As we previously reported, Whitney was found dead in a bathtub on Feb.11 at the Beverly Hilton hotel.

Whitney Houston's close friend -- Raffles van Exel -- is "extremely relieved" he is not in the crosshairs of the Beverly Hills Police Department in the singer's death investigation.

Several reports were posted this week that someone removed cocaine from Whitney Houston's hotel room before authorities arrived, and the reports say cops were targeting van Exel.

The stories are not true, because we know authorities actually found cocaine in the Beverly Hilton hotel room and cops are satisfied they have all the evidence they need to close the case. 

Our sources assure us ... there is no investigation focusing on anyone removing evidence from the hotel room.

As for van Exel ... we're told he's going to the Beverly Hills PD next week with his lawyer to make sure they're square with him.

Authorities recovered cocaine in the hotel room where Whitney Houston died ... TMZ has learned.

As for the quantity of cocaine that was found, official documents show one of the items police recovered was "white, powdery remnants." Sources tell us the powder was tested and it's cocaine.

We're told Beverly Hills detectives are NOT investigating rumors that someone removed cocaine from the room, because they're convinced it wasn't removed.

Sources directly involved in the investigation told TMZ early on ... no illegal drugs were recovered from the room. We have circled back with these sources who now tell us they were unaware at the time that cocaine was present.


Bottom line -- cops are in the final stages of their investigation, but they are not focusing on anyone who possibly removed cocaine, because authorities are in possession of the goods.

Whitney Houston's mother believes Bobby Brown's DUI arrest proves what she's been telling people all along ... he's just a bad dude.

Sources close to Cissy Houston tell us ... she's always felt Bobby was a cancer ... who infected Whitney's life with negative influences.

We're told Cissy felt "vindicated" when she found out Bobby was arrested for driving drunk on Monday afternoon ... and believes the incident is exactly why she wants Bobby to "keep his distance" from his daughter Bobbi Kristina.

The Houstons believe Bobbi K has been in a "vulnerable place" since Whitney passed ... and as one source puts it, "This is the last person she needs to be around."

Instead, we're told Cissy wants Bobbi Kristina to hang around "positive mentors" ... like Clive Davis.

The 4th floor Beverly Hilton hotel room where Whitney Houston died is officially off the radar -- after hotel staff removed the infamous door number ... 434 ... and TMZ has photo evidence.

Sources tell TMZ, the number was removed shortly after she died -- after scores of prospective hotel guests called to request the room.

A rep for the hotel tells us, the number was removed because the room has been taken out of circulation. So far, there are no plans to make the room available to future hotel guests.

The L.A. County Coroner's findings on Whitney Houston's death has not settled the case -- by a long shot.  Fingers are pointing in all directions, casting blame. 

So we gotta ask ...

Ray J is pissed that people are accusing him of being Whitney's enabler and, even worse, fueling her with the fatal dose of cocaine.

Ray J's rep tells TMZ ... the singer had NO KNOWLEDGE that Whitney was using again.

The rep says Ray J is especially upset at claims made by Bobby Brown's sister, Leolah Brown, who went on TV Thursday night and suggested Ray J was to blame for Whitney's demise.  Ray J says the claim is absolute B.S.

Sources connected to Whitney Houston who were with Whitney the day she died tell TMZ ... an individual removed all traces of cocaine from the room before authorities arrived.

The Coroner's Office says Whitney used cocaine "immediately prior to her collapse."  Investigators who arrived on scene found no traces of cocaine or any other illegal substance.

One source who is extremely close to the situation tells us ... the individual who removed the cocaine was also the person who supplied it to Whitney.

As we previously reported, other items were removed from the room as well, including bed sheets.

The Beverly Hills PD just told TMZ ... its investigation is not closed.  Cops will not comment on whether they are looking at evidence tampering.

An official for the L.A. County Coroner's Office just stated ... Whitney Houston used cocaine immediately prior to her death.

Coroner Chief Craig Harvey just held a news conference -- claiming the toxicology results suggested Whitney was a "chronic" cocaine user.

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.

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.

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.

Whitney Houston had cocaine in her system when she died -- this according to the L.A. County Coroner.

The L.A. County Coroner has just released the singer's official cause of death -- accidental drowning ... but the report also notes heart disease and cocaine use were contributing factors to Whitney's demise.

Officials say Houston also had traces of marijuana in her system ... as well as Xanax (anxiety medication), Flexeril (muscle relaxer) and Benadryl (allergy medication).

A source connected to the investigation tells us it is "very possible" Whitney had a heart attack that caused her to lose consciousness and drown. The heart attack may have been triggered by hardening of the arteries as a result of cocaine use.

As we previously reported, Whitney was found dead in a bathtub at the Beverly Hilton hotel last month and several pills were found on the scene -- including Xanax, Ibuprofen, and Midol.

Investigators found NO EVIDENCE of cocaine in the hotel room.

Law enforcement sources have told us from the beginning they did not suspect foul play -- and believe her death was not a homicide.

Her family however had doubts about Whitney's demise -- suggesting there may have been foul play.


3:01 PM PST -- The Houston family has released a statement which says, “We are saddened to learn of the toxicology results, although we are glad to now have closure.”
