Is it right that adhd medications can have long term side effects like cardiovascular and other problems ? or it is relatively safe ?

Risk vs benefit ADHD: Anyone with a significant cardiovascular history personally or in the family should be thoroughly checked out for cardiac disease prior to starting on any of the psychostimulants. Having said that however this class of medications is incredibly safe and has far more benefits than risks. Some of the benefits include an average increase in school grades of two points, meaning that if someone is getting c grades they are likely to go up to a's. Teens who are unmedicated have four times the risk of car accidents and five times the risks of fatal car accidents then they're treated peers.Also, there is a far lesser chance of incarceration and substance abuse in those who are treated.
