I'm sorry to say that's not the case, I read how a young man died recently.  I'm pretty sure I read that on the ayahuasca.org forum, two or three months ago.  The forum members were analysing the autopsy results to find out what he'd taken.  They concluded (if I recall correctly) that he had drunk some ayawaska with a GRAM of DMT for some inexplicable reason... which is 20 times the breakthrough dose.
