Lindsay Lohan's Dad Says She's Smoking Meth or Crack

Lindsay Lohan recently appeared in public flashing seemingly decayed, yellow teeth. Now her estranged father Michael Lohan says its a result of her doing illegal drugs.

“That’s from smoking a pipe with meth or crack,” Michael Lohan said in a televised interview. “She’s smoking either crack or meth, one or the other. I’m not going to shade it.”

The troubled actress bypassed her court-mandated shoplifting awareness class last Friday to have emergency dental surgery to fix her teeth, according to Radar Online.

In particular, it was observed that Lohan’s two front teeth were particularly damaged.

“If you’re talking about prescription medication it would affect all your teeth, not just your two front teeth,” Lohan said in the interview.

Addiction specialist Dr. Eric Braverman, author of "The Edge Effect," told Pop Tarts how smoking drugs can affect your teeth.

“Crystal Meth and Crack can damage your teeth,” Braverman, who does not treat Lindsay Lohan, said. “Meth and crack damage teeth as well as make them brown. In addition, these drugs blow out the brain system using up all the happiness hormone, dopamine.”

Dr. Sack, CEO of Promises Treatment Centers, who does not treat Lohan, agreed that dental decay is one of the signs of such drug use.

“Crack cocaine and crystal methamphetamines potently constrict the blood supply in the gums," he said. "This causes characteristic changes in the teeth in many individuals who are habitual users as a direct result of their drug use."

Dr. Gayle Randall, who works at Passages Malibu drug and alcohol treatment center, concurred, saying “tooth decay and periodontal disease are often associated with drug and substance abuse, particularly with crack which is smoked through pieces of Brillo which has other toxins in it that are harmful to the teeth.  Any drug, including crystal meth, that is smoked can harm the teeth and erode enamel.”

A rep for Lohan said he would not “dignify (Michael’s) comments with a response.”

Lindsay Lohan is not currently being tested for drugs or alcohol.

The actress had her probation revoked on Wednesday for not fulfilling her community service obligations. Lohan posted $100,000 bail and was released. On Thursday she was turned away from the L.A. County Morgue, where she was ordered to do do community service ahead of a November 2 court hearing, for failing to turn up on time.

Lohan’s new-found European modeling career is in jeopardy if she is unable able to make scheduled overseas appearances, according to the rep who set up her contract with the Philipp Plein fashion house.

“Lindsay Lohan for a number of years has been untouchable for major studios and brands as she just has been completely irresponsible. From drugs to DUIs to temper tantrums, she's too much of a risk for big companies to associate with, but she's now worth a gamble for some smaller companies simply because of the inherent guaranteed press bonanza she brings with he,” PR expert and author of “For Immediate Release,” Ronn Torossian added. “That said, she's still young enough that she may eventually be able to recover and America is a forgiving country. I wouldn't completely write her off just yet.”
