Yes, one dose of iboga got me clean. I was addicted to opiates/opioids for about 7 years. 3.5 of those were spent on methadone. I reduced from 100 mgs a day down to 12 mgs a day over a year or so, then flew to the Netherlands to do the iboga treatment with Sara Glatt. It took a couple weeks before I really felt normal in my skin, and I was still kind of worn out and had a general lack of energy for a few weeks. But I was clean from methadone and all opiates, for 5 years after that single dose. There was no unbearable withdrawal, only very minor symptoms compared to any of the other 7 clinical detoxes I had tried before starting the methadone maintenance program. I even used a couple times right after I returned, because I didn't listen to Sara and take some boosters. However, I did successfully quit. I also quit smoking cigarettes within 5 months and stopped eating sweets and drinking sodas.
I broke my collar bone in 09 and they put me on vicodin. After a couple checkups, they could only medicate me and let it heal, so I switched to poppy pods, which were cheaper than doctor visits, since I had no insurance. After I was healed, I again did iboga to kick. I have been clean since, again, and the pods/morphine I was using were much, much easier than kicking methadone.
Iboga effectively reduces opiate withdrawal from about 80-100% for most people. It also can eliminate cravings for numerous other drugs, including alcohol, cigarettes, cocaine, and methamphetamine. With opioids there can be some post acute withdrawal that lingers, especially for drugs like suboxone, or methadone, with extremely long half lives. It is often recommended that someone switch to shorter acting opiates for a few weeks before undergoing iboga treatment, to make it easier. Another option is to take small boosters of iboga extracts or bark, as needed, to eliminate the post acute withdrawal until your body/brain are again producing your own endogenous endorphins. The psychedelic aspect allows people to get to the root of their problems often, and the action on the receptors keeps them from craving and experiencing withdrawal.
If you'd like to google GDNF and ibogaine, there are some scientific articles on some of the action of ibogaine on the brain. It seems to do a lot to repair the dopamine/endorphin system, which is why people recover much faster when using iboga to detox. It is remarkable medicine, and there have even been some clinical trials done by Deborah Mash.
The problem is, who stands to make money on something that cures addiction? Even if one had to do 2 grams of ibogaine each time, and had to do it even 15 times before it stuck, that would only be 30 grams of ibogaine. The money is in maintenance drugs, that is why the establishment pushes methadone and suboxone, or baclofen for alcoholics. Something you have to take to be okay makes a lot more money than something that addresses the root of the problem and allows someone to totally walk away from an addiction. It has proven effective on multiple types of addictions and other amazing things are reported by people who have undergone treatment, but it may still be a good long while before we will see iboga in any mainstream treatment centers.
The anti-addiction properties were discovered by Howard Lotsof (RIP) who apparently was the first (or one of the first) guy(s) in the US, to be busted for LSD, and he was also a former heroin addict. He was given some ibogaine by a chemist friend, and he decided to take it. When it kicked in he had a remarkable trip, and when he awoke the day after the effects wore off, he noticed he was no longer dope sick. He later spent his life trying to promote ibogaine and bring it to the scientists and the masses.
I don't want to clutter up Pandora's thread too much more, but there is a lot of information about it on the internet. Take a look at some of the science and the reports, and see for yourself!
