Seminar Schedule

Dr. Harold Crossley



Is marijuana addicting? Is crack more addictive and/or less expensive than other forms of cocaine? What is "crystal meth"? Can a person become addicted to crack or heroin with one use? How is the heroin of today different than that of the past? How will I know if a person is under the influence of street drugs? What's toad licking? what are the new "party" drugs? What's a "club drug". Do I have to take any precautions with the dental patient who is under the influence? Why is it so important that my staff be knowledgeable about street drugs? Why am I at risk?

 The dental practitioner and staff as health care providers, have an obligation to be familiar with every aspect of a patient that will impact on their dental treatment. The practitioner should be able to respond to the patient who admits to a chemical dependency and is seeking help. The active addict and the chemically dependent patient who is in recovery require special aftention. For example: a recovering alcoholic may have degenerative liver disease and should be cautioned regarding large doses of acetaminophen. The recovering heroin addict should not be prescribed an opiate for analgesia because of the increased likelihood of relapse. A patient under the influence of cocaine. methamphetamine. or ecstacy who inadvertently receives an intravascular injection of local anesthesia with vasoconstrictor may experience a hypertensive crisis.

These and other examples illustrate the complications that might arise when treating the chemically dependent patient. This six-hour presentation will take you from the streets and into the office and help you identify the substance abuse patient. Discussion includes the origins, types, mechanisms of action and signs and symptoms of commonly abused prescription and illicit drugs. The evolution of and a biochemical explanation for addiction will also be discussed.
