I spew seed then proceed to smoke some blue weed
A new breed, I'm on speed, doped up like Lou Reed
I liked the rhyming here, despite the end rhymes not matching syllable wise. It could've been even longer, but you threw that "like" in there. This could've worked too:
I spew seed then proceed to smoke some nice blue weed
A new breed, I'm on speed, doped up like Lou Reed
Otherwise, this was a nice piece. Especially for your first time (posting at least). Tons of references haha
