Drugs & Alcohol

Sambora told our photog at JFK he was feeling good -- which was evidenced by the fact he signed dozens upon dozens of autographs for fans.

He arrived from Los Angeles, but planned on heading right back out -- he's meeting up with Jon and the boys for the European leg of the tour. They are scheduled to play in Croatia on Wednesday.

The University of Florida sent out an email to students participating in their study abroad program in Italy -- which states "any student who does agree to participate in the filming of the show, or who signs a waiver or legal agreement of any sort with MTV, will be dismissed from the program immediately."

TMZ obtained the email -- warning the students that any action deemed potentially embarrassing to the school "will not be tolerated."

The school has also threatened to contact the student's parental units to inform them why the school would be kicking them to the curb.

Funny, we thought the U of F mascot was the Gator ... not the Rat.

UPDATE: The UF is now changing their tune ... TMZ spoke with Janine Sikes, UF Director of Public Affairs, who tells us, "Generally speaking, students may participate in activities outside their Study Abroad program as long as they meet the academic and living requirements of that program."

Law enforcement tells us ... cops stopped Frankie for a routine traffic violation yesterday when they noticed an active warrant out for her arrest stemming from a probation violation.

We're told cops then performed a search -- and found "drug-related material" on her person.

Lons was arrested and transported to a nearby jail -- where she was booked for the probation violation and misdemeanor possession of drug-related material.

MiLo, who was involved in a fiery drunk driving accident back in 2005, recorded a public service announcement for a website called drinkinganddriving.org.

Quaid spilled his guts about his cocaine addiction in the '70s and '80s to Newsweek ... calling it his "greatest mistake."

Quaid explained, "I’d wake up, snort a line, and swear I wasn’t going to do it again that day. But then 4 o’clock rolled around, and I’d be right back down the same road like a little squirrel on one of those treadmills."

Quaid says he finally realized the severity of his addiction when his band broke up ... saying, "I kind of realized I was going to be dead in five years if I didn’t change my ways. The next day I was in rehab."

Law enforcement sources tell TMZ ... highway patrol in Grand Forks found Angle sitting in his car in the median separating lanes. We're told Angle told cops he had hit an icy patch in the road. During the conversation, cops say they smelled alcohol on Angle's breath. He failed a field sobriety test and was arrested.

Since cops didn't see Angle driving, he was arrested and later charged with being in control of a motor vehicle while intoxicated -- which basically means he was allegedly drunk behind the wheel but not actually driving.

In the 11-page letter, obtained from sources connected to Charlie, Warner Bros. states, "Your client has been engaged in dangerously self-destructive conduct and appears to be very ill."

The letter then goes on to describe Charlie's hijinks, including trashing the Plaza Hotel in NYC, coke binges, on-set failures because of drug fatigue, and diatribes against "Two and a Half Men" creator Chuck Lorre.

The letter also notes that Charlie derailed production when he went into rehab, and then he fired his sobriety coach. In fact, Warner Bros. claims it was so concerned about Charlie's well-being, "Warner Bros. had an airplane waiting" to take him to a treatment facility ... but Charlie would have none of it.

As for why Charlie got fired, the letter says there is a clause in his contract saying they can fire a performer who commits "a felony offense involving moral turpitude."

The letter says, "There is ample evidence supporting Warner Bros. reasonable good faith opinion that Mr. Sheen has committed felony offenses involving moral turpitude (including but not limited to furnishing of cocaine to others as part of the self-destructive lifestyle he has described publicly) that have 'interfere[d] with his ability to fully and completely render all material services required' under the agreement."

In short, that's why Charlie was fired.

Charlie's lawyer, Marty Singer, has demanded Warner Bros. pay Charlie for the eight canceled episodes -- or else.

Two months after TMZ first posted the video -- Miley has told Marie Claire, "I'm not perfect ... I made a mistake."

When asked if she was judged unfairly compared to other kids her age -- the actress said, "But they're not Miley Cyrus ... They're not role models. So for me it was a bad decision, because of my fans and because of what I stand for."

Sources who were present at Charlie's house during his 36-hour party tell us ... after a man delivered a briefcase full of cocaine to the house early Wednesday morning, Charlie pulled out a small green pipe and started smoking cocaine continuously ... for hours.

There are many wild details, but we're told eventually Charlie ended up in his theater room with one of the porn stars with whom he was partying. They watched 3 hours of porn, as Charlie critiqued the action on the screen.

We're told Charlie, who fancies himself as a porn connoisseur, was questioning his companion about angles and body shots. We're told the porn star was "surprised" by the depth of Charlie's knowledge.

As we previously reported, cops found 262 Vicodin pills, 180 Somas, 555 milliliters of anabolic steroids -- plus a residual amount of powder cocaine -- in Hardy's North Carolina home.

Now, with Hardy reportedly ready to plead guilty to at least one of the drug charges in exchange for a lesser sentence ... Hardy tells us, "I'll make the best of it, bro."

Bridges was roaming the halls at the ICDC College campus in Van Nuys, CA last week -- where he talked to students about his past addictions ... and explained how substance abuse counselors helped him kick the junk.

Miley, who has taken a lot of heat since TMZ posted the story that she was smoking salvia, has been saying, she's just young and having fun ... this, according to friends in direct contact with her.

Miley acknowledged she's seen the TMZ story and also knew it was going to eventually surface. As TMZ first reported, Miley's camp was trying to bury the incident by scooping up copies of the video.

According to people who deal, legally, in salvia divinorum ... sales have increased since Friday -- in some cases up to 3 times the usual tally.

TMZ spoke with several head shops in the Los Angeles area and we're told -- not only have sales jumped -- but many of the customers specifically asked for "the stuff Miley was smoking." No ... mentioning Miley did not get them a discount.

While Miley's experimentation is generating curiosity in the hallucinogen -- one smoke shop employee tells us, "Salvia is one of those things that you only try once because it is so intense."

Another impact of the Miley video -- as we reported -- is renewed discussion about banning salvia in California. It is already illegal in 15 states.

Miley arrived in New Orleans last week to shoot "So Undercover" -- and sources close to the production say hours after TMZ published the video of Miley taking bong hits ... she showed up for rehearsals.

We're told Miley and her co-star -- Kelly Osbourne -- ran through script lines, as scheduled, on Friday. According to our sources ... Miley knew the bong video was out, but "she kept her focus on the movie."

The video was shot during a party at Miley's L.A. area home 5 days after her 18th birthday.

According to a source connected with Miley ... the smoke filling the bong is a natural herb called salvia which has psychedelic qualities. Possession of salvia is legal in California.
