Japstyll3 was correct. Freud had two "addictions". He like, many other medical men, experimented with cocaine and morphine and he was addicted to smoking cigars. He smoked a box of cigars a day and continued to smoke even after he had severe cancer of the jaw. By the time he died, his jaw had decayed on one side through his face and was the main reason he died. These addictions were not his only problems. He had other neuroses, which was no more than what might be said of other people even today. He had a problem with anyone who disagreed with his theories in any way and rejected anyone who suggested modifications, such as Carl Jung and Alfred Adler. He required absolute loyalty and argued that for scientific acceptance of his theories, people had to conform strictly to its principles.
Freud needs to be judged on his accomplishments, and some of these accomplishments had nothing to do with his theory. He opened the closed doors of Victorian Europe. Although there were many behaviors and practices going on in secret, Freud brought these out in the open and discussed how they were affecting people's psyche and their effects on society, the most well known being that of sexual behavior and the hypocritical lives of royalty and the nouveau riche.
