Drugs & Alcohol

Lil Wayne got dissed by Diddy's posse in Miami, and it came thiiis close to blowing up into a replay of Drake and Chris Brown's infamous bloody nightclub battle.

This time the drama went down in LIV Nightclub at the Fontainebleau Hotel on Sunday night. Sources in the club tell us Wayne walked over to say hello to Diddy, who was in a VIP booth next to the DJ.

The beef started when Diddy's security stopped Weezy and wanted to search his posse. We're told Wayne didn't take kindly to that ... ended up spilling his drink on a bodyguard, and then things escalated quickly -- with both posses shoving each other.

We're told Wayne and Diddy got in the middle of the fray, and there was a lot of yelling back and forth ... but ultimately cooler heads prevailed. They ended up shaking hands, walking away -- and, based on the vid in the club, having a great night.

Big difference from Diddy's run-in with Drake in LIV last year.

Ex-Cleveland Browns star Eric Metcalf says ENOUGH IS ENOUGH when it comes to Johnny Manziel -- and the team should finally drop the QB because he's a magnet for bad publicity.

Metcalf -- who was a stud for the Browns back in the '90s -- says the latest example is Manziel's brush with police last week ... in which his GF claimed the QB hit her a couple of times during a domestic dispute, though Johnny was ultimately NOT arrested.

"I don't think he should be with the Browns, just because of all the things he's gotten into. It's all bad publicity," Metcalf says.

"He's not really helping the football team right now and every time you hear his name it's negative. At this point they should move on. It's tough to say about a player, but at this point, they should move on."

Boxing star Antonio Tarver says he "vehemently refutes" reports that he failed a drug test before his August fight with Steve Cunningham ... saying, "I am 100% innocent."

Tarver is responding to an article on SI.com -- which says he tested positive for synthetic testosterone, which is considered a banned substance.

But Tarver says he "categorically denies taking any banned substance before his fight with Cunningham."

"I have no idea how my urine sample tested positive because I didn't take anything illegal," Tarver said.

"Either the test was contaminated, or mixed-up with another sample. We believe in the process and I will fully comply. Further analysis will prove I'm 100% innocent because I've done nothing wrong."

It's been nearly 30 years since NCAA basketball superstar Len Bias died from a cocaine overdose ... just two days after he was selected as the #2 overall pick in the NBA Draft.

Now, with Lamar Odom fighting for his life in a Vegas hospital, Len's mother, Dr. Lonise Bias, says people must understand that drug addiction is a disease -- and it needs to be treated before it's too late.

Dr. Bias issued a statement to TMZ Sports ... complete with a heartfelt message to Lamar ... and a reality check to the rest of the sports world.

Zac Efron is sober ... and if you say otherwise, you could lose your job.

An extra on “Neighbors 2” learned that lesson the hard way this week, after he Instagrammed a pic from the set showing a baggie filled with fake weed, with the caption, "Thanks for the weed Zac Efron! BTW it's only a prop, people."

Apparently the disclaimer wasn't enough. The extra was 86'd almost immediately. Our source says it wasn't the first time the extra had gotten in trouble for inappropriate posts.

We're told Zac was not involved in the decision to fire the guy.

Efron went to rehab in 2013, so it's a sensitive subject.

Snoop Dogg is going to bat for disgraced USC coach Steve Sarkisian ... saying he knows the man personally and thinks he's worthy of another shot on the sidelines.

It's a huge statement from Snoop -- not just because he's a HUUUGE USC fan -- but because he's got a history of calling out NFL and college coaches when he thinks they should get fired ... even at SC.

So, when he was leaving Supperclub in Hollywood the other day ... we had to ask if he thinks Sark should be put out to pasture permanently for allegedly being liquored up around his players.

The situation with Lamar Odom is forcing people to come to grips with a harsh reality -- addiction is a deadly serious problem that can't be ignored ... so says D.L. Hughley.

The actor/comedian was leaving Barney's in Bev Hills when we asked for his thoughts on the situation -- and he gave us the brutal truth.

"Anybody who's dealt with somebody with addiction knows that generally that's how it ends up ... and it's always sad when it does."

He added, "It's hard for him and his family."

Lamar Odom has not gotten any better, and sources familiar with his treatment say even if he survives he has virtually no chance of ever leading a normal life.

Our sources say doctors continue to put Lamar's chances of survival at 50/50. We're told he showed "absolutely no improvement" Thursday from the condition he was in when he was admitted to the hospital Tuesday. As one person put it, "He's in dire straits."

One of the big issues is Lamar's apparent consumption of cocaine and an herbal substitute for Viagra, which is a potentially deadly combination.

We're told he was "entirely unresponsive" all day Thursday and 4 vital organs are still failing, with no signs of improvement. Lamar is not breathing on his own and his doctors believe his brain function is significantly reduced.

We're told the Kardashian family has flown in several specialists from L.A. to consult with Vegas doctors.

One source said there are comparisons to the plight of Bobbi Kristina, with one big difference. We're told Lamar did not lose oxygen to the brain for nearly as long as Bobbi Kristina, which offers some sliver of hope.

Doctors have told the family for each day that passes without improvement, the prognosis gets bleaker.

You can't turn the Steelers logo into a bunch of marijuana leaves ... or else you'll face the wrath of the NFL ... so says a pot group in Pittsburgh that just got lit up with a nasty legal threat.

The bud beef is all over the logo for the Pittsburgh chapter of NORML -- a massive nonprofit group dedicated to legalizing weed.

They've been using a logo similar to the famous Steelers design for years -- with the asteroids swapped out with red, yellow and blue ganja leaves.

Problem is ... some square at the NFL caught wind of the logo and fired off a cease and desist -- warning the group to 86 the design .. or else! (Guess that paranoia was justified this time).

Turns out ... the people at NORML are more smokers than fighters and told us they're backing down and plan to change the logo ASAP because they don't want a war with the NFL.

Two NORML honchos, Patrick Nightingale and Jason Cole, tell TMZ Sports they're already coming up with a Pittsburgh-themed replacement logo -- "Maybe Andrew Carnegie holding some weed."

Former Playboy Playmates Karissa and Kristina Shannon were rushed to the hospital Monday after a horrific accident where Kristina rolled their SUV ... and then got arrested for DUI.

Sources close to the twins tell us they were on their way to get their nipples pierced (yes, really) when Kristina lost control of their G-Wagon in Beverly Hills. Karissa had to be pulled from the vehicle through the windshield and firefighters cut open the SUV's roof to rescue Kristina.

Law enforcement sources tell us the twins were taken to a local hospital for treatment. Amazingly, they made it out with just scratches and bruises. Kristina was cited for misdemeanor DUI while she was still in her hospital gown.

Sadly, getting wasted in public has kinda become the girls' thing lately.

Lamar Odom took 10 Reload pills over the course of 3 days before he fell into unconsciousness -- according to people at the brothel -- and the FDA says the pills are so dangerous they've advised consumers to throw them away IMMEDIATELY.

The FDA determined Reload contained sildenafil, the active ingredient in Viagra. The label does not reveal the presence of that ingredient, which is normally restricted to prescriptions monitored by a doctor.

The FDA says sildenafil can "lower blood pressure to dangerous levels."

The FDA sent a warning to consumers in 2013, saying, "Consumers should stop using this product immediately and throw it away."

The brothel sold Reload and Lamar got it when he arrived. The Sheriff seized the remaining inventory of Reload from the display case.

Cops confirm TMZ's story ... that someone from the brothel told the 911 dispatcher Lamar Odom confessed to her he had used cocaine days before he lapsed into unconsciousness, and if cops determine it's cocaine it's "distinctly possible" he'll be prosecuted.

Nye County Sheriff Sharon Wehrly just said her dept. obtained a search warrant and drew blood from Lamar in the hospital Wednesday, and the blood will now be tested for drugs.

As we reported, sources tell us doctors found cocaine in Odom's system.

Scott Disick is back in rehab ... partly in hopes of winning a victory in his child custody battle.

Sources connected to Disick tell us he checked in last weekend to a facility in Malibu, and has not only admitted he has a problem ... but cut ties with some of his usual party pals.

We're told Disick took the leap because of his kids -- he's gunning for unsupervised visits. He's told friends Kourtney Kardashian won't let him have unsupervised visitation until she knows he's clean. Us Weekly first reported Scott's effort to get clean.

Disick made an abbreviated run at rehab earlier this year when he went to a center in Costa Rica that used hallucinogenic plants for treatment. He lasted a week before bailing.

The person who made the Lamar Odom 911 call tells TMZ, he told the dispatcher Lamar confessed to doing coke days before he lapsed into unconsciousness.

Richard Hunter, media director of Love Ranch South, tells TMZ one of the women who found Lamar Tuesday afternoon unconscious in his room came running down the hall, screaming for him. Hunter says when he saw Lamar, he immediately called 911.

The dispatcher asked if Lamar had done drugs or consumed alcohol. Hunter says one of the girls said Lamar had consumed cognac and had taken a "s***load" of an herbal substitute for Viagra. When pressed, she said he took around 10 in the 3 days he was there.

Hunter then said he pressed her to see if Lamar had done any drugs, and the woman said he admitted to having taken "a small amount of cocaine" before he arrived on Saturday. Hunter says he conveyed that information to the dispatcher.

What doesn't make a lot of sense ... why would Lamar confess to doing coke just before arriving but not doing it once he got there?

As we reported, we're told doctors have determined Lamar had coke in his system.

Lamar Odom had cocaine in his system and track marks on one of his arms ... so claim witnesses at the hospital where Lamar lies unconscious.

The witnesses tell TMZ ... doctors have determined the former NBA star had cocaine and opiates in his system -- but it's still unclear if the track marks are fresh or from previous drug use.

We're told doctors have told people close to Lamar the fluid they found in his lungs was the result of crack cocaine use.

We're also told several of Lamar's party friends have come to the hospital to see him but they were turned away.

Sources at the Love Ranch where Lamar was staying have said he was taking an herbal substitute for Viagra but no drugs were found. Dennis Hof who owns the Ranch tells TMZ he can't swear Lamar wasn't doing drugs in his room.

Lamar Odom locked himself away in quiet, relaxing surroundings when he started his weekend getaway at a Nevada brothel.

We got these shots inside the VIP suite at the Love Ranch South outside Pahrump, Nevada ... where, as we reported, LO had been hanging out since Saturday.

Love Ranch owner Dennis Hof refers to the pad as his "house," since he stays there when he's visiting -- but it's usually rented out to VIP clients.
