Keywords: sold a slave to my original evil The first stage of Dr. Henry Jekyll's addiction is Robert Louis Stevenson's nineteenth century novel Dr. Jekyll and Mr. Hyde, addiction is a very important undertone. Stevenson writes "It had been on this area that my new vitality lured me until I fell in slavery. I had fashioned but to drink the glass, to doff simultaneously your body of the known professor, and to assume, like a thick cloak, that of Edward Hyde" (Stevenson 109). In other words, Dr. Henry Jekyll concocts an extremely strong potion in his lab and beverages it. Due to his ingesting the potion, he changes into the evil Mr. Hyde. In Dr. Jekyll and Mr. Hyde, Dr. Jekyll evidently shows all the basic signs to be a medicine addict: experimentation, denial, attempt to quit and misuse.
