Ch. 4: Summary

In this Module 9 coursebook, you learned some basic principles about the class of substances called sedative/hypnotic and central nervous system depressants. We explored which drugs fall into this category, including some of the “club” drugs. Topics discussed included the nature and effects of these substances. Our discussions also introduced concepts that are relevant across many types of substances, not just this particular class of substances. This included some basic pharmacokinetic principles, issues of polydrug use, prescription versus non-prescription use of medications, driving under the influence, accidental overdose, and suicide risks.

You are now ready to review some of the key terms related to substance use disorders that were introduced in this book.
