Which drug can lead to the heart or arteries bursting and causing a massive coronary?

The correct answer is based on the effects of crack cocaine on the cardiovascular system. Crack cocaine is known for its powerful stimulant properties, leading to an increased heart rate and elevated blood pressure. This excessive stimulation can place immense strain on the heart and the blood vessels, increasing the risk of severe cardiovascular events, including heart attacks, strokes, and potentially causing the arteries to rupture. The acute effects of crack cocaine can lead to sudden cardiac events, making it particularly dangerous.

While codeine is an opioid that primarily affects pain relief and does not have the same stimulant impact, amphetamines also cause increased heart rate and blood pressure but are not as strongly associated with the risk of arteries bursting. Phencyclidine (PCP) can alter perceptions and cause dissociative effects but doesn't primarily lead to cardiovascular failures in the same way crack cocaine can. Thus, crack cocaine's significant association with acute coronary events and vascular damage solidifies it as the main choice in this context.
