Which of the following drugs can cause the heart or arteries to burst and result in a massive coronary?

Crack cocaine is known to significantly impact the cardiovascular system and can lead to severe complications, including coronary artery damage. The use of crack can cause vasoconstriction, where blood vessels tighten, increasing blood pressure and heart rate. This heightened stress on the heart can result in a variety of dangerous conditions, including increased risk of heart attacks and arteriole rupture, also known as massive coronary events.

Unlike the other substances mentioned, which may have different effects on mood, perception, or psychoactivity, crack cocaine's stimulant properties and its propensity to cause significant cardiovascular stress make it particularly dangerous in this context. This is crucial for whoever is in charge of guiding or educating others about the risks associated with drug use, especially in the military environment where health and readiness are vital.
