Prior to beginning work on this discussion, read the required chapters from the text and review the required articles for this week. Alcohol and caffeine have nearly opposite effects on behavior and the nervous system, yet these substances are not used to treat overdose or addiction to the other. Why not use caffeine to treat alcohol addiction? Analyze the issues of pharmacological and physiological antagonism. Explain the receptor systems involved and the central nervous system structures effects with regard to this question. Frame your analysis in terms of drug action first and other consequences second.
Guided Response: Review several of your colleagues’ posts and respond to at least two of your peers by 11:59 p.m. on Day 7 of the week. You are encouraged to post your required replies earlier in the week to promote more meaningful interactive discourse in this discussion.
Evaluate your colleague’s analysis. To what extent was he or she accurate? Please use your research to support your assertions. Did the analysis take into consideration all the required elements?
