we just found out that my step son (5yrs old)has been taken clonidine from his mother nightly that has been prescribed to his sister and other people. He has no problems that would lead up to him needing to take it. No adhd or anything. Hes a normal little sweet boy. What can i do to prevent this? Can i just take him to the hospital and get tested or something? can this be listed as child/drug abuse? How long does it stay in the system?
