Even a single 25mg dose of Adderall can cause significant increases in blood pressure, heart rate, and activate the body's stress-response system in individuals not regularly prescribed the medication.

How common is non-medical Adderall use among college students?

Prior studies indicate that a substantial percentage of college students, ranging from 23% to 43%, have used Adderall or other stimulant medications during periods of high academic stress.

College Students: Adderall's Hidden Heart Risk

•

Summary

A single Adderall dose significantly increases heart rate and blood pressure.
Non-medical Adderall use is rising among students for study purposes.
The drug elevates stress hormones, potentially risking heart rhythm issues.

A recent Mayo Clinic study, published in the March 2026 issue of Mayo Clinic Proceedings, highlights significant cardiovascular risks associated with the non-prescribed use of Adderall by college students. Researchers found that even a single 25-milligram dose of Adderall can cause a substantial increase in heart rate and blood pressure in individuals not accustomed to the medication.

The study involved 30 healthy participants without ADHD. Results indicated that within three hours of taking Adderall, blood pressure and heart rate spiked. The drug also led to a surge in norepinephrine, a key stress hormone, indicating activation of the body's "flight-or-fight" response.

This research underscores the acute stress Adderall can place on the cardiovascular system for those using it without a prescription for medical reasons. The findings suggest these effects could be exacerbated by concurrent use of caffeinated beverages, potentially increasing the risk of serious heart rhythm abnormalities among young people. Further investigation is needed to fully understand the short- and long-term dangers of this trend.
