Counselor:
To become a licensed counselor, someone must complete a master's degree in counseling and then complete hands-on work as a counselor (under supervision). The number of required hours of hands-on training varies by state. Many counselors specialize in addiction treatment for drug and alcohol abuse, and the majority receive training in psychotherapy techniques. In terms of substance abuse issues, where therapists deal specifically with healing the root causes of a person's addiction (childhood, trauma background, etc.), counselors deal with the current day-to-day needs of the person. This involves what's called case management, which can include things like housing (which halfway house are you eligible for, or where are you going to live after you get out of a treatment center?); child care (how can you you get your child back if custody is jeopardized by addiction issues?); employment services (informing you about job placement programs), etc. Many times, counselors can also help with interventions, whereas most therapists do not.
MS:
A master of science (MS) is an advanced degree, usually in the natural sciences, mathematics, engineering, agriculture and computer science. There are multiple MS degree program options in the fields of mental health, psychology and counseling. A master's degree is often required to become a licensed therapist, counselor or social worker. Someone with an MS in mental health counseling might practice as a rehabilitation counselor working with patients struggling with substance abuse or addiction. MS programs vary by the college or university, but typically involve hands-on learning.
LMHC:
A Licensed Mental Health Counselor (LMHC) is someone licensed by a state board to provide professional counseling and mental health therapy. A licensed mental health counselor must have a master's degree in counseling or psychology. Mental health counselors often provide both individual and group counseling. Some mental health counselors focus on helping individuals overcome substance abuse or addiction. Working with a mental health counselor can be very beneficial for someone struggling with alcohol or drug abuse. Some counselors are trained in helping families and loved ones stage an intervention.
NCC:
A National Certified Counselor (NCC) has a master's degree in counseling. To obtain NCC professional certification, counselors must have completed at least 100 hours of supervised counseling over the course of two years. They must also have at least 3,000 hours of counseling work experience over two years. Someone with an NCC certification must comply with the code of ethics and conduct of the National Board for Certified Counselors (NBCC). A counselor with this degree can work at a substance abuse rehab facility, and work with people with mental health issues. Some counselors specialize in helping with interventions.
