How can you tell if crack is real?

To determine if crack cocaine is real, you should look for its distinctive appearance: it typically comes in small, off-white or yellowish rocks. Real crack usually has a hard, glassy texture and may produce a distinct smell when heated. Additionally, testing it in a safe environment with chemical reagents can confirm its composition, though this method requires proper knowledge and safety precautions. However, the best approach is to avoid illegal drugs altogether, as their use carries significant health and legal risks.
