I have a 15 yr old son with ADHD.  He was diagnosed in 1st grade, but only since 6th has it become a real problem.  ADHD kids have very low self esteem due to the constant frustrations and negative feedback they get.  They frequently do great in sports. They are usually about 2-3 yrs younger emotionally than their counterparts even though physically they are their age.  This makes them very suseptible to bad influences, they want to fit in some where.  They want to feel 'normal'.  If you are not heavily involved in his life, setting limits and making them accountable, pointing out bad choices/consequences and good ones, restricting his social life, becoming one to one buddies with his teachers and school counselor, your child will fall through the cracks.  He might even then.  Did you know that depression and 'mood disorder', (which is trouble with anger and strong emotions), and even bi-polar disease are commonly found with ADHD kids. Is he in counseling?  Is he on medicine?  Do you understand why it's vital for a ADHD kid to take medicine?   A counselor gives him someone to bounce his thoughts and feelings with, once they're trusted, and also helps you learn to help your child.  (An outside counselor, not a school counselor.) There is info on the internet, books written, but talking one to one with other parents helps.  Most of us ADHD parents feel like a lone island in the middle of the ocean, struggling to keep our heads/and our kids head, out of the water.   I wish you luck with your child.  It's so frustrating because they are also so full of wonderful potential, and can be really great kids if you can look beyond the ADHD.
