Expressing disagreement with a statement, the speaker mentions the responsibility of those who buy illegal substance and proposes actions to be taken against them. What is the speaker talking about and what actions are they proposing?
I could care less if you "disagree".  Google it and see for yourself.  What about the scum that knowingly and willingly buys the stuff?  What should be done with them?  The "scum" that sells it would not be selling it if there weren't "scum" willing to fork over the $$$ to buy it.
