Checkmat..
There is no chance of testing positive for DMT.
They simply don't test for it, its in tons of plants, and your body naturally right now, and only psychoactive when taken with an MAOI inhibitor.
That's all ayahuasca is, some high DMT concentration plant + some MAOI inhibitor.
If you have serious anxiety issues you should probably take some other less intense psychedelics first... starting out dmt would be akin to cliff jumping into the ocean, to get over your fear of water, before you know how to swim, alone, at night.
Once your subconscious starts feeding your conscious its just you and yourself. That's the beauty of all hallucinogenic drugs, its just you and you, reflecting on yourself through the world around you.
I'd aim for LSD, mushrooms, or a 3rd plateau dxm trip (available at your local walgreens in both liquid and pill form) before you go running overseas to take the holy grail of hallucinogens.
Personally I am quite experienced with almost all hallucenogens (LSD, dxm, mushrooms, 2ci, 2ce, and diphenhydramine, salvia, ket, MDMA, etc). and id suggest considering these things before going in.
Family history of schizophrenia?
How well do you handle not being in control?
Have you tripped in the past and were you able to relax, remember you were on a drug, and enjoy the ride?
and
Are you well researched on all possible negatives and poaitives from a non biased source? If not your buying a trip without researching where you're going. You wouldn't do that with a plane, why do it with your consciousnesses.
Go to erowid.com
Research any drug you consider doing, they have experience reports, scientific studies, dosage estimates, everything you could possibly need for every chem imaginable.

Don't lightly go into a trip. That's how people end up freaking out. This is a vision quest. Treat it with reverence for you only get out what you put in.
LSD and DXM helped me cure my depression, but they were the means... not the end. I highly recommend tripping to deal with personal issues, just be sure to use it as a tool to evaluate your life from a new perspective, not an escape.
DMT is the only mainstream trip I have not experienced, but all of my friends who have compare it to salvia in strength, and I would not send someone to salvia for a first trip.... it would be too much to comprehend.
If you are experienced, trip away.
Go read experience reports for ayahuasca and DMT (same drug different effect lengths, will be easy to split apart in reports) on erowid.
Just essays of peoples experiences.
Find the similarities and prepare before you go in.
Its just safety prepping.
Then, trip away if you feel confident.
Best of luck man.
