Develop a presentation that addresses the effects and properties of each major substance of abuse and the effects on human beings. Design your presentation so that it could be used in a school setting for 4th through 8th grade students. Make sure to include:
- A listing of frequently abused substances
- A comparison of the properties/effects of hallucinogens, stimulants, and narcotics and the effects they have on the body
- A description of the drug to include the "pleasurable" properties
- A description of the negative effects and symptoms on the body (both seen and unseen).
