Over 160 signs related to drug and alcohol use are clearly illustrated, along with notes on the derivation of each sign. A good resource for parents, interpreters, teachers and counselors. Companion video to the Signs of Drug Use text presents both front and side view of the signer. Signing is clear and easy to read and offers various ways to sign a word including synonyms and slang. Excellent supplementary material to the text. [James Woodward; 60 minutes] DVDs not returnable once opened.
