Medicines and Drugs: What’s Helpful, What’s Harmful
The goal of module 4 of the NIDA Junior Scientists Program is to introduce children to the topic of medicines and other drugs. During the first three modules, we introduced the parts of the brain and the process of neurotransmission so that now, by module 4, the children have some understanding of the complexity of the central nervous system. Children are learning information about the effects of drugs on the body. Drugs can be divided into two categories: helpful medicines and harmful drugs. One group of drugs, with a beneficial effect on the body, includes medicines that they have probably taken—aspirin/Tylenol, antibiotics, immunizations, and fluoride. The other category, which can have harmful effects on the body, includes alcohol, nicotine, and illegal drugs, such as marijuana and cocaine.
One of the points we emphasize in the module is that all these substances are powerful. Even helpful drugs must be taken under the right conditions and given by trusted individuals—parents or health care professionals, for example. If too much medicine is given, that can be just as dangerous as taking an illegal substance. For example, the drug Adderall is an effective treatment for ADHD, but when it is taken in doses higher than prescribed or without a prescription, it can cause many harmful effects and even death. Drugs and medicines can be both helpful and harmful. Therefore, all substances must be handled with care.
We encourage you to ask your child about this learning experience. Try to find out how much he or she understands and what is still fuzzy. Work with your child to clarify points that he or she hasn’t yet grasped. Help provide your child with more knowledge so that when the time comes, he or she will make a solid, science-based decision not to take drugs.
Science at Home
Discuss certain lifestyle choices made in your home. For example, if you have a glass of wine with dinner, explain that your choice is okay because you are an adult, are drinking in moderation, and are not doing anything dangerous, such as driving after drinking. Emphasize that adults can make these choices, while children are not yet old enough. By learning about how the brain works and about drugs, however, your child is getting a foundation to make thoughtful decisions in the future.
