High Blood Pressure
Earlier we explained how some smart drugs work to increase the blood flow to the brain. But this can have a serious side effect of increasing blood pressure. They may also speed up the heart rate and affect the vision. Prescription drugs like Modafinil and Adderall can produce this effect.
That’s why it’s crucial to consult a doctor before using nootropics like these. It’s risky to use them because the side effects can cause serious consequences. High blood pressure may lead to strokes or heart attacks so it’s very serious. Young people don’t think this way when they’re using them (via Medical News Today).
