Osmond knew LSD produced symptoms similar to delirium tremens. Many times, alcoholics attribute their ability to quit drinking to the horrific experience they have withdrawal and not wanting to go through it again.

He was astonished when the patients had interesting rather than frightening experiences on the drug. Also, 40-45% of those treated had stayed sober a year after their treatment.
