The most robust and effective people have often benefitted from self-titration of drugs that are quite dangerous in the hands of the incompetent. Adderall has been the gold-standard “go pill” for fighter pilots and scientists since World War II, as well as elite lawyers, and bankers. Freud used to take (and offer to friends) small pinches of cocaine throughout the day. Special forces doubtless use similar doping regimens to that of Lance Armstrong. This seems all to the good because it gives America an edge.
