Intriguing, I had the impression it was mostly used as a recreational drug, but I stand corrected.It seems to me, in some situations, that the drug community is ahead of the curve in some respects.e.g. Ketamine as an anti-depressant, Modafinil as a cognitive enhancer.Because they are basically able to do what pharmaceutical companies are unable to do due to legal and ethical restrictions on humans.i.e. experimental pharmacology vs a more theory based approach.Nothing wrong at all with the pharmaceutical approach and using animal test subjects, but often in science it is blind stabs in the dark, or 'blue sky research' as it's formally known, that delivers results (contrary to popular perception, most scientific discoveries are 'blue-sky' rather than directed research).
