This is an entirely appropriate use of drugs.

This article from the New York Times looks at a study about a husband and wife who are using MDMA (ecstasy) to treat patients with post traumatic stress disorder.
They are seeing a success rate of nearly 80% 1-5 years after treatment with no side effects.
That's pretty damn amazing - except that it's not.
Because, MDMA was initially developed as a "therapy" drug.
According to patients who have received psychoanalysis along with the drug, it allows you to re-experience the traumatic event without being overwhelmed by it.
One soldier said that it felt like he could go in to whatever memory he had and fix it.
And it allowed him to move forward without the feelings of guilt and anger he had prior to taking the drug.

Pretty cool stuff.
And if the research bears to be accurate for the broader population, will eliminate the need for drugs like Paxil and Wellbutrine which have very real side effects.
