Free drugs

I found this new drug, it’s great.
One hit, and I’m high for days.
I’m getting some tomorrow, can’t wait.
I’ve been up all night.
Couldent sleep at all.
Just thinking about going to this place. 

I can do a tonne of this stuff,
and not even loose face.
The dealer is nice,
don’t have to pay.
Or even sneak in the back way.
Watch out for the dog.
Or make sure I lock the gate.
All I do is sign the library card,
And I’m on my way.
