Youth Mental Health First Aid -- Join the movement. Sometimes first aid isn't a bandage or CPR. Sometimes, first aid is YOU. A young person you know could be experiencing a mental health or substance use problem. Learn an action plan to help. Anyone 18 or older can take Youth Mental Health First Aid, but it is recommended for those who regularly have contact with young people ages 12-18 -- teachers, coaches, social workers, faith leaders and other caring citizens.
