You will need to begin researching how you can obtain a certificate to be a substance abuse educator. Make sure that when you find a program that it is accredited. You may find some within universities and community colleges. They are usually a part of other programs that teach about mental health, education, psychology, social work and health.
Next, you will need to learn all you can about the different substance abuse organizations and resources that are out there. Begin speaking with people that work in drug education. You can get in touch with your town's board of education to see if they know of any substance abuse educators. You can also get in touch with support groups to find out more information about the field. Try speaking with individuals that are enrolled in these support groups to see how they feel about the programs. Visit a school when they are having an orientation about drugs, when educators come to speak with the students. Look around the net to locate substance abuse plans that have worked.
