PCN 501 Week 2 DQ 1: Tolerance and Withdrawal
A counsellor does not prescribe or detoxify, which is exactly why this matters: they are often the person who sees the client first and has to recognise what is happening.
Editorial process
Last reviewed · August 16, 2026
Two clinical concepts, and both change what you do
Define both terms precisely before arguing anything, because the argument depends on the definitions. Tolerance is a reduced effect from the same dose, so that more is needed to achieve what a smaller amount once produced. Withdrawal is a substance-specific syndrome that appears when a dependent person reduces or stops use, and its features are the opposite of the drug's acute effects: stimulant withdrawal produces crash, fatigue and low mood, while depressant withdrawal produces agitation, tremor and autonomic arousal. Both are physiological adaptations rather than moral facts, and both appear in the diagnostic criteria for substance use disorder, so a counsellor assessing severity is already using them whether or not they can name the mechanism. Note that neither concept is the same as addiction: a patient on long-term prescribed opioids can be tolerant and physiologically dependent without meeting criteria for a substance use disorder, and conflating them is a clinical and a moral error.
Then answer the question the prompt actually asks: why this matters to a counsellor specifically. Four reasons carry it. Safety comes first, because alcohol and benzodiazepine withdrawal can be fatal while opioid withdrawal is agonising but rarely so, and a counsellor who cannot tell those apart may reassure someone who needs urgent medical assessment. Second, interpretation: irritability, poor concentration and flattened mood in the early weeks may be withdrawal or protracted withdrawal rather than a new mood disorder or resistance to therapy, and treating them as personality or motivation is a clinical error. Third, relapse risk, since withdrawal discomfort is a principal driver of return to use and knowing the timeline lets you plan support around the worst days. Fourth, psychoeducation and stigma reduction, because a client who understands tolerance as an adaptation rather than as evidence of weakness has a different relationship to their own history.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Define tolerance and withdrawal accurately and separately.
- 02Distinguish withdrawal syndromes by substance class and by danger.
- 03Recognise withdrawal presentations that mimic psychiatric or motivational problems.
- 04Use physiological understanding for psychoeducation and stigma reduction.

Here are some helpful links Student paper example Citing Sources The Writing Center is a great resource Welcome to class Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to. I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you. Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted. If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations. Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements. Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week. I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!

Review before submission
Common mistakes
- Defining tolerance and dependence as the same thing.
- Treating all withdrawal as equally dangerous, or equally benign.
- Reading early-abstinence flat mood as a primary depression.
- Answering with pharmacology and never reaching counselling practice.
Submission checklist
- Are both terms defined separately and correctly?
- Have you identified which withdrawals are medically dangerous?
- Is there a presentation you could misinterpret?
- Have you connected the concepts to what you would say to a client?
