Mmm, weed... Always a good subject...
This is actually pretty good, man. The one glaring issue I have with it is the vocals clipping so much in parts. Maybe it's your mic, if so I'd say go pick up a nice condenser mic with a pop filter.
You're right that the chorus is a little off. In my opinion if you shouldn't rush shit like that, no reason to fuck up your whole song because you didn't feel like doing the chorus right the first time.
Lyrics could be better, you got some weird syllable counts, but I'm not really complaining too much since I'm not exactly a lyrical genius myself.
All in all you got some potential; lose the clipping, make sure the chorus sounds crisp, and tweak the lyrics a bit and you've got some pro shit right here.
