Stevie discusses his time in ECW with talent who worked drunk, high, or on pills. He joked about Sandman working drunk being better than sober, including the "sweet spot" of how many beers Sandman needed to work well in the ring.
He then talks about the current independent wrestling scene and investing time in researching a new opponent, such as watching YouTube videos in order to better understand what he will do in the ring. Then he discusses how disappointing it is should that person be under the influence when about to perform, with Stevie considering it disrespectful and wasting his time as a professional after investing his time to prepare for the match & to entertain the crowd + any fans watching online.
He had some interesting takes on the topic, so you might find this of interest.
