In Stabler's case, it was more of a byproduct of years of drinking, smoking, and occasional drug use, which in his autobiography he sort of hints at like taking codiene but tends to not elaborate further. Stabler was also known as a bit of a hell-raiser and trouble maker in Gulf Shores Redneck Riviera as well as a womanizer and a bit of a philanderer. One time his wife caught him in bed with another woman when she arrived home earlier then expected and in a fit of rage, she locked him out of his house with barely any clothes on.
