Rock Bottom

Try to guess the poster's message before reading below:

The goal was to make a dramatic poster utilizing positive and negative shapes. In the center there's a white H, a common term for Heroin. A skull and syringe make up the negative shapes within the H. 

"Hit rock bottom, in attempts to get high" was chosen as a vague tagline. 
"Hit" alludes to the action of taking a hit of heroin. 
"Rock" is meant to hint at Black Tar. 
"Bottom" and "High" were chosen as a play on words because they contradict each other.
