Schedule I — drugs with a high abuse risk. These drugs have NO safe, accepted medical use in the United States. Some examples are heroin, marijuana, LSD, PCP, and crack cocaine…
In 1981, the Texas Legislature passed a law which required doctors to write all prescriptions for Schedule II drugs on a special three‑part or triplicate form. Effective September 1, 1999, the triplicate prescription form was replaced by an official prescription form. Any triplicate prescriptions that are in use are still valid prescriptions and may be used until the supply is depleted. The new official forms are issued by the Texas Department of Public Safety to prescribers. Pharmacies electronically transmit prescription information to the DPS. The information is used by licensing boards to identify doctors, dentists, and/or pharmacists who may be inappropriately prescribing or dispensing these highly abusable drugs. In addition, the DPS can identify potential abusers much more quickly and stop any abuse, misuse, or diversion in a more timely manner. The program has been very effective in reducing abuse, misuse, and diversion of Schedule II drugs in Texas.
