My esp connection is down today, and I can't see your author or the article.

We Jiskha tutors are good -- but unfortunately we haven't learned to read minds.

To determine the answer to this question, we need to understand which illegal substance is being referred to in the context of highlighting racial discrimination in the criminal justice system.

The options given are:

1) crack & powder cocaine
2) pot & meth
3) crack & pot
4) pot & heroin

Based on the question, we can eliminate options 2) pot & meth and 4) pot & heroin because they don't include the substance crack, which is specifically mentioned in the question.

This leaves us with options 1) crack & powder cocaine and 3) crack & pot. However, the use of powder cocaine alone does not highlight racial discrimination as explicitly as the combined use of crack cocaine, which has historically been associated with racial disparities in sentencing.

Therefore, the correct answer is 1) crack & powder cocaine. The illegal use of crack cocaine highlighted the presence of racial discrimination in the criminal justice system.
