I always thought Hop was pretty much speed. Ya know, "Man, I'm all hopped up" Nickatina has a skit on New Jim Jones where a studio technician calls Nickatina a hop head. Now Jacka be saying he's hooked on hop and calls it brown, so that makes me think its heron. But he also has a verse where he says he was "pushin smack I was two steps away from using" if hop is heron and smack is heron, he says he was two steps from but didn't say he was using. E-40 says he was pushing marijuana and hop. Maybe someone can clear this up for me. Thanks.
