So the Dept of Defence reviewed the literature and found no evidence that mefloquine causes permanent neurological and psychiatric damage?  Clearly they did not look very hard, because there is lots of good evidence available.  They might start with: Malaria Prevention, Mefloquine Neurotoxicity, Neuropsychiatric Illness, and Risk-Benefit Analysis in the Australian Defence Force published in Dec 2015 in the Journal of Parasitology.  Anyway, who decided that the experiences of individuals outside some contrived lab are "anecdotes" and OK to ignore?  Canada, we have a problem.
