Authorities have released the full toxicology report from the autopsy of Rudy Eugene — the man who made headlines after he chewed another man’s face off in Miami on Memorial Day Weekend — and, contrary to popular belief, it looks like bath salts, or any other outrageous drugs for that matter, were NOT behind the gruesome attack.

According to a statement on the full toxicology report by the Miami-Dade medical examiner, the only drug detected in the 31-year-old’s lifeless body …. was marijuana. MARI … FREAKIN … JUANA!

[Editor's note: We know weed gives people the munchies ... but DAYUM!]

Medical examiner Dr. Bruce Hyma said in his statement, “The laboratory has tested for but not detected any other street drugs, alcohol or prescription drugs…This includes cocaine, LSD, amphetamines (Ecstasy, Meth and others), phencyclidine (PCP or Angel Dust), heroin, oxycodone, Xanax, synthetic marijuana (Spice), and many other similar compounds.

A second forensic toxicology test conducted by a separate lab also confirmed the absence of the most comment ingredients found in bath salts, which mimic the effects of cocaine or methamphetamine and have been associated with various bizarre “zombie attack”-like crimes in recent months, and many — including Miami police officials — believed they were what caused Rudy Eugene to attack Ronald Poppo, and chew off at least 70% of his face.

“Within the limits of current technology by both laboratories,” the statement continued, “marijuana is the only drug identified in the body of Mr. Rudy Eugene.”

But that doesn’t necessarily mean weed — literally the least harmful “drug” known to man — is what made Rudy Eugene eat Ronald Poppo‘s face. According to the Miami Herald, the medical examiner’s report didn’t address previously reported autopsy findings of what appeared to be undigested pills in Eugene’s stomach … so we’ll most likely never know what really unhinged Eugene and caused him to act so violently

As Dr. Bruce Goldberger, Professor and Director of Toxicology at the University of Florida, noted in a report from the Associated Press, “The problem today is that there is an almost an infinite number of chemical substances out there that can trigger unusual behavior,” adding that the medical examiner’s office in Miami is known for doing thorough work, and he’s confident that they, as well as the second lab, covered as much ground as possible.

Still, Dr. Goldberger says that it’s almost impossible for toxicology testing to keep up with all of these new street drugs that literally come out of nowhere.

“There are many of these synthetic drugs that we currently don’t have the methodology to test on, and that is not the fault of the toxicology lab. The challenge today for the toxicology lab is to stay on top of these new chemicals and develop methodologies for them, but it’s very difficult and very expensive.” Goldberger said. “There is no one test or combination of tests that can detect every possible substance out there.”

Dr. Patricia Junquera, who is an assistant professor at the University of Miami Miller School of Medicine, and is considered an expert on addictions, said she wouldn’t rule out the fact that a different “strain” of marijuana could have caused the attack.

“It could have been the strain of marijuana that increases the dopamine in the brain,” she said, adding that there are two strains of marijuana called sativa, which increases dopamine and gives you energy, and indica, which is a “sleepy high.”

“People don’t really know what the amount of either is in each little packet of marijuana,” Dr. Junquera explained. “And we can’t differentiate between the two in the blood, much less in a dead person.”

She also suggested that if Eugene suffered from a mental health condition, “the marijuana could have increased even further the dopamine levels and aggravated the situation,” which, she says, is why marijuana can’t be totally ruled out.

It’s been a little over a month since the May 26th incident, and officials still have no clue what led 31-year-old Rudy Eugene to attack Ronald Poppo, a 65-year-old homeless man who was asleep moments before the assault occurred.

Surveillance video from the Miami Herald’s parking garage nearby captured the 18-minute attack, in which Poppo woke up to Eugene stripping him naked, and beating him senseless, while his attacker used his bare teeth to chew off pieces of the flesh from his face.

The police officer who shot and killed Eugene said he growled at him, with pieces of Poppo’s face hanging from his mouth, when he was told to stop.

Surprisingly, the homeless man survived the bizarre attack, however … to this day, Ronald Poppo remains in a Miami hospital with some of the most serious injuries to his face doctors have ever seen.

According to local reports out of Miami, Rudy Eugene — a former football player for the North Miami Beach High School — was once diagnosed as schizophrenic after an arrest, and authorities are unsure as to whether or not he sought treatment for the condition.

Eugene was also reportedly accused of threatening to kill his mother in another incident in which he was arrested. But despite all of that, his friends and family members say they never expected the man they knew to commit such a horrific act.

Eugene’s friends and family have said that he was a religious, non-violent person, and that he didn’t drink or do any drugs other than marijuana. Eugene was reportedly participating in a Bible study and telling friends he wanted to stop smoking weed.

“There’s no answer for it, not really,” Eugene’s younger brother, Marckenson Charles, said in an interview. “Anybody who knew him knows this wasn’t the person we knew him to be. Whatever triggered him, there is no answer for this.”

Charles said that Eugene has been buried, and his family doesn’t plan on pursuing any legal action against the Miami PD for killing Eugene because they understand that the police had to use “the force they felt was necessary, even if we don’t agree with that.”

Meanwhile, despite the victim’s injuries (he lost an eye and his nose, and must undergo another round of reconstructive surgery), Ronald Poppo is said to be “doing well,” according to doctors at the Jackson Memorial Hospital’s Ryder Trauma Center.

His doctors say that mental health professionals have been helping him with the coping, and he’s coping “remarkably well.” Poppo’s family has said that they haven’t been in contact with him for more than 30 years and thought he was dead.

Now that we know that “bath salts” didn’t do it (and we know marijuana for damn sure didn’t do it)…

What do you think caused Rudy Eugene to attack Ronald Poppo, and chew more than half of his face off?

Freddy Sharp knows exactly what it feels like to be high on “bath salts” … and he says it’s not a good feeling.

“Balth Salts” — not to be confused with the scented bath salts you would buy at Victoria’s Secret or Bath & Bodyworks and put into your bathtub — is the synthetic drug that the “Miami Cannibal” Rudy Eugene is believed to have been on when he chewed off a homeless man’s face off last month.

The horrific 18-minute attack, captured on video surveillance cameras nearby, only ended after Eugene was shot dead by police. The victim remains in critical condition at a Miami hospital with close to 80% of his face missing.

“The guy just kept eating the other guy, like ripping his skin,” witness Larry Vega told reporters, adding that when Eugene was told to stop, he growled like an animal with flesh hanging from his teeth, and continued to eat the victim’s face.

According to officials, the synthetic drug known as “bath salts” are marketed under that name because they are usually sold in smoking paraphernalia stores disguised as a common household product, with a label that reads “not for human consumption.”

They contain amphetamine-like chemicals such as methylenedioxypyrovalerone (MDPV) and are sold as “cocaine substitutes” or “synthetic LSD.” Its effects include paranoia, hallucinations, convulsions and psychotic episodes.

27-year-old Freddy Sharp, a self-proclaimed drug addict since the age of 13, describes his overdose on bath salts as the “darkest, evilest thing imaginable.”

Shocking video footage of Sharp shortly after taking the highly potent drug — commonly called the “new LSD” shows the Tennessee native squirming around, and then making faces and singing to himself while he is strapped down by paramedics.

Sharp told CNN that he was hallucinating about being in an insane asylum and being possessed by Jason Voorhees from the “Friday the 13th” movies.

“I just felt all kinds of crazy,” said Sharp, who says he hasn’t used bath salts in months, ever since the overdose convinced him it was time to quit. “It felt like impending doom was coming down on me,” he recalled. “I felt like I was about to bust loose and actually hurt somebody.”

Though Sharp says he never felt the urge to “eat anybody’s flesh,” he admits the drug did make him feel invincible.

“You feel like you’re 10 feet tall and bulletproof, and you actually do not feel any pain,” he said … which explains why it took police officers over half a dozen shots to kill Rudy Eugene — who was apparently strong enough to actually hold someone down, and use his bare teeth to rip almost 80% of their face from their head.

Freddy Sharp gave a warning to other users of bath salts:

“The only thing I can say to them is that if you value your life, you’ll stop it and you won’t do it anymore, because it will destroy your life. It will destroy your family. It will destroy everything.”

The involvement of “bath salts” in the horrific attack on Ronald Poppo remains unverified, as police weren’t able to recover anything from the crime scene, and Rudy Eugene’s autopsy didn’t reveal too much either; though a toxicology report is expected to be released in the next couple of weeks.

Police in Miami believe that the naked homeless man who was shot and killed while he ate the face of another homeless man may have been high on a dangerous drug known as “bath salts.”

Miami police identified the cannibalistic attacker as 31-year-old Rudy Eugene. His victim — identified as 65-year-old Ronald Poppo — remains in critical condition in a Miami-area hospital after at least 75-80% of his face was chewed off.

Hospital staffers say Poppo is suffering from “some of the most horrific injuries” they have ever encountered, and he is completely unrecognizable after Eugene ate part of his nose, cheeks, ears and eyes.

The harrowing attack, which has shocked the world, took place Saturday afternoon (May 26) on a freeway bridge near Miami Beach.

According to police, Rudy Eugene, who they believe had come from a Memorial Day weekend beach party, stripped a sleeping Ronald Poppo naked, beat him, then proceeded to chew lumps of flesh from his face and head.

Eugene continued to eat the man’s face even after a Miami police officer shot him in the chest.

An eyewitness said that Eugene growled like an animal when officers told him to stop before they shot him half a dozen more times, killing him instantly.

Stomach-churning images of Ronald Poppo’s horrific injuries and the crime scene have gone viral.

The photos of the crime scene show a partially-clothed Poppo laying next to his fully nude attacker, and blood is everywhere.

Another set of photos, allegedly taken at the hospital, shows the extent of Poppo’s injuries, and the massive destruction done to his face and head. His facial features are non-existent, and all you can see is a bloody eye and a blood-soaked goatee.

The uncensored images are pretty gruesome, and aren’t for the faint of heart. (CLICK HERE to check them out — but you’ve been warned!)

Doctors, police and news reporters all theorize that Rudy Eugene was high on “bath salts,” a dangerous drug that mimics the effects of highly potent (and illegal) substances like cocaine, LSD and meth-amphetamines.

As Dr. Howard Mell, an emergency room physician from Ohio, noted to CBS News: “These are not the bath salts you buy at Victoria’s Secret … There’s not soap in them.”

Mell says that at least seven people — all under the age of 27 — have died in the two Cleveland-area hospitals where he works at as a result of using “bath salts,” which can cause severe agitation, rapid heart rate, high blood pressure and a number of other ailments.

The drug can also lead to the body overheating, which explains why Rudy Eugene stripped completely naked before his savage attack.

Users of the dangerous drug also experience hallucinations, lose touch with reality and can exhibit psychotic behavior, though calling Eugene’s behavior “psychotic” would be an understatement.

EMS workers who have responded to cases involving users who are high on “bath salts” say that they exhibit super-human strength and don’t respond to stun guns or tasers.

Several workers — and sometimes even burly police officers and/or security guards — are usually required to hold down a person who is high on “bath salts.”

“Addictive substances, whether they are bath salts, alcohol or other drugs, can have horrific and costly consequences. Sometimes these consequences can result from only one use; other times they are a result of the complex brain disease of addiction,” says Susan E. Foster, vice president and director of policy research and analysis at The National Center on Addiction and Substance Abuse at Columbia University.

“Together, risky use of addictive substances and addiction constitute our nation’s largest and most costly health problem. In the interest of health and public safety, Americans must begin to understand that substance use is a preventable public health problem and addiction is a treatable disease,” she added.

According to Jeffrey Scott, a spokesman for the Federal Drug Enforcement Agency, “bath salts” – the street name for the drug that is considered a replacement for cocaine or a synthetic form of the hallucinogen LSD — can be snorted, smoked, or broken down and injected.
