First ever attempt at writing a Rap

This is my first attempt are writing a rap or spitting some bars as they say here in the UK grime scene lol

Any tips will be much appreciated and i don't mind if you guys want to edit/add/change it around so it flows a bit better that would be great Show me your raps if you've written one too
Here goes anyway

I've smoked alot of green
I been smoking weed like its oxygen
I'm like cheech and chong
I been hitting up my bong
All day long
Now time passes but it feels a lil slower
Got no weed left, starting to get lower
Now all i need
Is a nice bag of weed to use in my brand new blower
Man, when i be smoking that super super haze
I could just sit back and laze
Be on my ass for days and days
I'm High already smoked one blunt
And now my eyes feel heavy
Yet i keep blazing on steady
Now my appetite suddenly increases
Its like i could eat 4 more pizzas.

Thats it so fair The beginning and ending is a bit dodgy but what do you guys think of my first attempt?

Thanks, Mickie5001

first attempt ever? nothing wrong with the rap. it could use some word play, and rhyme schemes in between but i think it's fine for a first attempt. definitely keep on workin on it and keep on smokin!

btw they say spittin bars in the us too

Aww Thanks Man and yeah i was sat in Engineering materials at college bored as fuck and couldn't stop thinking about weed so started writing this :L
