The use of cocaine can cause damage to the heart and cardiovascular system, and the amount of cocaine that causes heart damage can vary depending on individual factors such as age, overall health, and frequency of use.

Cocaine use can cause a range of cardiovascular problems, including high blood pressure, irregular heart rhythms, heart attacks, and stroke. The risk of heart damage increases with the amount and frequency of cocaine use. Even small amounts of cocaine can cause temporary increases in heart rate and blood pressure, which can lead to heart damage over time.

Chronic cocaine use, especially in high doses, can cause more severe and long-lasting damage to the heart and cardiovascular system. For example, a study published in the American Journal of Cardiology found that cocaine users who used the drug more than twice per week were at significantly higher risk of developing heart problems, including heart attack and heart failure, compared to non-users.

Overall, the use of cocaine can cause serious and potentially life-threatening damage to the heart and cardiovascular system. It is important to seek medical attention if you or someone you know experiences any symptoms of heart problems after cocaine use, such as chest pain, shortness of breath, or irregular heartbeats.
