Reality TV star Scott Disick checked into rehab
over the weekend -- reportedly for substance abuse-related health issues that have long been documented on E!'s Keeping Up with the Kardashians
-- and ET recently talked to Gerard Powell, the founder of Rythmia Life Advancement Center in Costa Rica where Disick is currently undergoing treatment.
First, Powell cleared up rumors that 31-year-old Disick was being paid six figures to go to his facility as part of a publicity stunt, and says that it's actually the other way around.
"He's not being paid to go to my facility. He's actually paying to go to my facility," he clarifies. "But, if it's successful -- and which we have every hope that it will be, because it's successful so much of the time -- then I would like him to be a paid spokesperson going forward because he can influence a lot of people and really, really help a lot of people."
Disick is receiving iboga treatment, which uses a special African plant to cure addiction. The iboga pant is sometimes used by proponents of psychedelic therapy to treat addiction, depression and post-traumatic stress disorder.
"What makes our center different from traditional 12 step programs is the plant itself -- the iboga plant," Powell explains. "And it's incorporating that plant into traditional therapies as well."
"This thing has been around forever and it's the first line of defense in that area of Africa for psychological disorders, personality disorders, and drug and alcohol addiction," Powell further claims. "And because of that they have a very high success rate with it over there. It's not dangerous compared to other therapies, and it has a tremendously high success rate at curing addiction."
But what are the effects of the iboga plant?
"It can be [hallucinatory]," Powell tells ET. "During that period after you ingest the plant, some people see visions. Others just have tremendous awareness. They are able to sit in silence and see why they did what they are doing and what the root cause of addiction is."
The cost of rehab at the Rythmia Life Advancement Center doesn't come cheap. Their longest/most expensive program is about $1,000 a day for 21 days. Their shortest stay is only a week, though Powell says if it doesn't work, you get your money back.
But his hopes are high for Disick, who he calls a "very normal guy."
"He's still in [rehab]," he shares. "And I understand he's doing well."
Disick confirmed he was going to rehab -- reportedly after being found drunk and stumbling shoeless around the lobby of Harrah’s Resort in Atlantic City last Sunday -- in a statement to Gossip Cop
"I realize my issues are bigger than me and I’m ready to truly remedy this struggle I continue to battle," he said. "While I have been unconvinced in the past of treatment and therapy methods, Rythmia's rehab approach puts my worries at ease. The fact that there is a money back guarantee that has never been called upon gives me even more confidence. I am looking forward to starting my therapy and iboga treatment there."
Meanwhile his longtime girlfriend Kourtney Kardashian -- with whom he has three children with (Mason, 5; Penelope, 2; and Reign Aston, who was born in December) -- is reportedly "tired" of his behavior.
"Kourtney is so tired. She has heard the same excuses again and again," a source tells People
. "He lives a lifestyle that is just so different than what Kourtney wants for her life and family."
