B. Users have increased heart rates.

Explanation:

Typical effects of marijuana include loss of concentrating skills, exhaustion or drowsiness, slower reaction times, increased heart rate, distorted time and distance, and reduced hand-eye coordination. The combination of most of these impairments makes driving under the influence of marijuana dangerous and often more fatal. However, while the increased heart rate can cause a greater risk of heart issues and heart attacks, it does not impair your driving as much as a slower reaction time or difficulty judging distances might. In the event of crash or near-crash, it can oftentimes be imperative that the driver swerves, brakes, or protects themselves. With these impairments, doing these necessary tasks in the moment becomes harder and slower, and may not even happen at all.
