Not everybody can undergo an ibogaine treatment. 

A stress test EKG has to be performed to make sure one does not have a heart condition, which could lead to complications during the treatment. If the patient is suffering from other conditions then additional checks need to be performed to ensure safety.

The physical sideeffects of ibogaine can include mainly vomiting and ataxia (reduced muscle control).

Psychologically it puts one in a combination of waking and dream state which has several distinct stages. It is often percieved as unpleasant by addicts as locked up memories get released in that state into the waking consciousness.

If performed by experts the administration of the treatment is psysically very safe. The treatment is performed in one day and the patient is given a few days to rest afterwards after which he can return home.

Most addicts do not have any more cravings for their favourite drug after ibogaine treatment, nor do they have any withdrawal symptoms. They are simply free again.

A kind of reset is performed. Many say its like cleaning up the hardware and updating ones own software. 

Since it was discovered in the west by accident thousands of former addicts have found a way back to life with the help of Ibogaine.

It is not a miracle treatment and does not prevent addicts of going into relapse if they really want to, but 65% of former addicts stay drug free after the first Ibogaine expierience due to its profoundness.
