Sandoz began to offer LSD to doctors and therapists. Sandoz saw it as a help to doctors and therapists so they could get a chance to gain insight into how someone who was mentally ill might see the world. It is known today, that the effects of LSD are very different from those of delusional mental illnesses, such as schizophrenia. For their patients, it was a chance to uncover hidden feelings and thoughts, which could be dealt with in therapy. LSD showed promise in the treatment of problems like alcoholism. Some alcoholics who tried the drug found their need to drink alcohol lessened or went away. They understood better why they had abused alcohol. Unlike other drugs, the desire for alcohol was not replaced by a craving for LSD. The study showed a 50% success rate, compared to 10% for "cold turkey" methods, which is when the person suddenly stops drinking alcohol completely.
