For this assignment, you are to write a paper 5 pages, excluding the cover page and references page, addressing the differences between addiction, tolerance and withdrawal.

You will first need to research the effects for the following classes of psychoactive drugs: opiates (heroin, Fentynal, Oxycodone); stimulants (Methamphetamine, Cocaine, MDMA (methylenedioxymethamphetamine), cannabis, tobacco, and; depressants (alcohol, PCP, Ketamine).

Next, use the additional resources in this module, course lectures and any other outside sources, to research the general effects of the following classes of psychotropic medications: Anti-depressants (SSRIs, Tricyclics, MAOIs); Anti-psychotics (typical, mood stabilizers), and: Anti-obsessive agents (anti-anxiety agents, SSRIs stimulants).

Imagine you are explaining the differences between tolerance and withdrawal to a person who is convinced withdrawal and tolerance means that a person is in fact addicted to a drug.  Address the following questions and be sure to cite the sources in your narrative and list references using APA style: 

In clear terms, explain what is tolerance and what is withdrawal, how these conditions develop, and if these are permanent or temporary conditions. You do need to explain every form of tolerance. 
Next explain and describe what are the key characteristics of addiction and how addiction differs withdrawal and tolerance to a drug. 
Now briefly explain how the following classes of psychoactive drugs affect the brain and can produce addictive effects: opioids (heroin, Fentanyl, Oxycodone); stimulants (cocaine, methamphetamine, MDMA (methylenedioxymethamphetamine); tobacco, cannabis, and  depressants (alcohol, benzodiazepines, barbiturates, PCP, Ketamine).  There is no need to explain each specific drug or its effects; just explain the common general effects of each drug class on the brain and central nervous system.
Finally, explain why opiates, tobacco, cannabis, stimulants, and depressants can lead to addiction, yet most psychiatric medications such as antidepressants, anti-psychotics, mood stabilizers, and anti-mania drugs do not lead to addiction. Explain the reason for this difference?
Brief write a summary conclusion of your narrative.
