Last week, I saw the story that Julia Roberts’ older brother Eric Roberts had joined the “cast” of Celebrity Rehab, but I didn’t think that much of it. Honestly, I’ve heard the rumors about Eric and his addictions, and I thought it was just more of the same. But I was wrong! It turns out that Eric isn’t addicted to crack or heroin or even tequila… no, Eric likes the chronic. He’s been tweeting (he’s on Twitter?!?) about his addiction to medical marijuana:

Eric Roberts checked into ‘Celebrity Rehab’ last week. His wife, Eliza, told E! that he would be treated for his addiction to medical marijuana.

“Eric quit drugs and alcohol in 1995,” Eliza said. “He has no interest in anything, other than marijuana.”

Eric, who is Julia Roberts’ brother and Emma’s dad, reportedly has a prescription for marijuana to treat his anxiety but wants to kick his dependency on it.

“Tweating By Remote to answer y I’m doing CELEBRITY REHAB . It’s not 2 get people 2 stop asking y I’m doing Y&R as some have proposed. LOL,” he tweeted Tuesday.

Eric made his debut on ‘The Young and the Restless’ a couple of weeks ago. His next project: moving out of the weed garden and in with troubled roommate Jeremy London.

“I’d like to move out of the weed garden & into a place where things can blossom & grow. The people @ #CelebRehab have been fantastic 1 & all,” he tweeted.

Maybe I’m not down with all of the hip stuff, but I’ve always doubted people’s claims that marijuana is addictive, or that a person can be a pot addict. I used to smoke up quite a bit (in my youth), and while I had some good times, I just didn’t understand how someone could be “addicted” to that feeling. Maybe I’m just close-minded about it. Or maybe Eric Roberts just likes to get high, and he’s not really “addicted”.

In other Celebrity Rehab news, Rachel Uchitel (“The Pillhead/Love Addict”) has already tried to quit the show because she found Dr. Drew to be too hardcore:

Rachel Uchitel told producers “I quit” and ran away from the set of Celebrity Rehab 4 — ditching the show for a swanky hotel after an intense day of filming drove her over the edge, RadarOnline.com has learned exclusively.

“After a very intense day of filming, Rachel just couldn’t handle being at the Pasadena Recovery Center where Celebrity Rehab is filmed, and she decided to leave,” a source told us.

Tiger Woods’ former Number 1 mistress bolted for the swanky L’Ermitage Hotel in Beverly Hills, RadarOnline.com exclusively learned. Her escape from rehab was prompted by a very intense day with Dr. Drew, and Rachel had trouble coping with the issues that were discussed, according to the source.

As RadarOnline.com reported exclusively Rachel is being treated for a problem with alcohol and an addiction to pills. She was discussing her issues with self-esteem and self-worth, along with her addiction to pills when she went over the edge and bolted the set for the L’Ermitage Hotel. Rachel told Dr. Drew that and producers that she was quitting the show, and she left, the source told RadarOnline.com. Producers of Celebrity Rehab 4 located Uchitel and went to talk to her the next morning. “Producers arrived at the hotel the following morning, and calm prevailed. Rachel simply needed some time away from the intense pressure and scrutiny that she is dealing with.

“She agreed to go back to Celebrity Rehab 4. Rachel has never had to face these issues before, and talking about it pushed her over the edge, and her instinct was to run. Producers made her realize that if she continues to run away from her issues, she will never be able to live a healthy life,” a VH-1 insider tells us.

Rachel isn’t legally allowed to talk about Tiger Woods, but he looms large in her life.

“Her issues go beyond Tiger, but he was the catalyst that pushed her over the edge,” a source tells us.

As we previously reported, VH-1 execs are so impressed with the footage that has been shot so far that a push is being made for the show to premiere sooner than the scheduled October date.

Sigh… I’m so glad I don’t watch this show, I really am. That being said, if Rachel does end up talking about Tiger Woods or David Boreanaz, I will gladly cover it. F-cking pillhead.
