Substance Abuse, Intoxication & Withdrawal, Uppers Downers & Hallucinogens MDMA LSD PCP
SKIP AHEAD: 0:32 – Substance Abuse vs. Substance Dependence 2:51 – Miosis vs. Mydriasis 3:21 – Uppers/Stimulants (Cocaine, Meth & MDMA/Ecstacy) 5:57 – Downers/Depressants Intoxication & Overdose (Alcohol, Opioids, Heroin) 10:58 - Downer Withdrawal 12:18 – Hallucinogen (PCP, LSD & Mushrooms) 14:15 – Marijuana/Cannabis Alcohol Link - http://www.stomponstep1.com/alcohol-metabolism-methanol-poisoning-fatty-change/ Psychosis Link - http://www.stomponstep1.com/psychosis-schizophrenia-schizoaffective-disorder-delusional-disorder-hallucinations/ Donate Link - http://www.stomponstep1.com/donate/ Substance dependence is an adaption to a pattern of substance use. It is primarily characterized by withdrawal (or symptoms that occur when use of the drug is discontinued), tolerance (or needing more to obtain the same desired effect), and spending a significant portion of their time engaged in drug related activities. Substance abuse is an overindulgence in an addictive substance as a result of a lack of control. It can be thought of as a more extreme version of substance dependence in which individuals have significant negative life effects with work relationships or school), poor health, or legal problems as a result of their substance use. In the general public this pattern of substance abuse would more generally be referred to as an addiction. There is very specific DSM criteria for each of these terms, but that isn’t important for the exam. For simplicity sake we will break the drugs down into 3 different categories. The 3 categories are Uppers, Downers and Hallucinogens. There are slight differences between drugs within individual categories, but for the most part you can get questions right by just knowing the general characteristics of the entire group. For example, you won’t see both cocaine and MDMA listed as answers on the same question. Also remember to not confuse intoxication and withdrawal. Most questions are on drug intoxication, but they may specifically ask you about withdrawal which usually has symptoms that are just the opposite of intoxication. So make sure you read the question carefully. For example, the question stem may fit stimulant withdrawal and depressant intoxication, but the last sentence of the question specifically asks about withdrawal. Keep in mind the most important things for Step 1 questions are the changes to the vitals and pupils. These should be the buzzwords you are looking for. You will almost always be given this information in these types of questions and if you just have that info you can usually narrow it down to at least 2 options. Also make sure you don’t get mydriasis vs. miosis confused. Mydriasis is the bigger word and has the bigger pupils. Miosis is the smaller word and has the smaller pupils. And obviously the best way to confirm a diagnosis of drug use is a urine drug screen and mental health services are important in the treatment of addiction. However, that is too easy so you won’t see either of those as an answer on the exam so I’m not going to spend much time on that. That brings us to Uppers or stimulants…. Now I’ll try my hardest to not make 20 references to Breaking Bad during this section, but I can’t make any promises. Most of the questions related to this category will be about cocaine, which is usually smoked in the form of crack cocaine or snorted. However, other street drugs such as Methamphetamines (Meth) & MDMA (Ecstasy & Molly) are also in this group. Prescription drugs used for ADHD, narcolepsy and weight loss are also stimulants, but are less likely to show up in this type of Step 1 question.

What is the Difference Between Acute Stress Disorder and Posttraumatic Stress Disorder?
This video discusses the differences between Acute Stress Disorder (ASD) and Posttraumatic Stress Disorder (PTSD). Both disorders require a qualifying stressor (trauma) according to the Diagnostic and Statistical Manual (DSM). This traumatic event must be directly experienced, witnessed, occur to a close friend or family member, or involve repeated exposure to aversive details of a trauma. PTSD is characterized by the developing of specific symptoms after a qualifying stressor. The general symptom categories include intrusion, avoidance, negative mood, and arousal. Specific symptoms include recurrent memories, recurrent dreams, dissociative reactions, avoiding thoughts, avoiding feelings, avoiding memories, avoiding external reminders, negative beliefs, memory difficulties, negative emotions, cognitive distortions, hypervigilance, self-destructive behavior, sleep disturbance, difficulty concentrating, recklessness, and anger outbursts. The criteria must be met for at least one month. ASD has a similar set of symptom criteria, however, the symptoms must be present for at least three days but no more than one month. After a traumatic event, individuals who are assessed for ASD may go on to develop PTSD. About 80% of individuals who are diagnosed with the full criteria of ASD will develop PTSD. About 60% of individuals who have subclinical ASD will develop PTSD. About 4% of individuals who do not qualify for ASD will develop PTSD.

TEDxTucson George Land The Failure Of Success
The theme of the TEDxTucson December 2011 event was "Innovating Our Green Economy. In his talk "The Failure Of Success", Dr. George Land gives us a brief history of human innovation and talks about the importance of creativity. George Land is an author, speaker, consultant, and general systems scientist with a broad and varied background in communications, business, education, and government. In 1958, when he was serving as chief executive of an international television network, he began investigations into stimulating and directing creativity. The encouraging results of those efforts led to his founding, in Cambridge and New York, Innotek Corporation, a research and consulting institute to further the knowledge about the enhancement of creative performance. This research ultimately led to the formulation of his Transformation Theory, a theory of transformation that integrates principles of creativity, growth, and change. TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. Our event is called TEDxTucson, where x = independently organized TED event. At our TEDxTucson event, TEDTalks video and live speakers combined to spark deep discussion and connection about sustainability. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.

How To Stop An Addiction ► Through Relapse Prevention
Do you want to know how to stop an addiction?click here for free video: http://truthofaddiction.com/special/ There is a common treatment for addiction that is to use "acute" rehabilitation. Yet it densest provide you with evidence backed ways of how to stop an addiction ore even how to help addicts in recovery. This video should help. Relapse is often treated as a sign of defeat instead of a stepping stone through recovery. There probably couldn't be a more harmful doctrine to an addict than to think that all the days, weeks, months or even years of sobriety didn't mean a thing because he slipped. Website: http://truthofaddiction.com/special/ YouTube: http://www.youtube.com/user/TruthOfAddiction1 Facebook: https://www.facebook.com/TheOfficialTruthOfAddiction At many therapy groups and 12 step programs, they may tell you that if you relapse you have to start all over again. They may tell you that no progress was made. But science tells us that huge strides are made both physically and psychologically. Research has shown that most relapses are caused by emotional states, not physical cravings as once thought. To tell an addict that all the days, weeks months or even years of abstinence didn't mean a thing because he slipped, feeds discouragement, depression and despair, the very emotions that lead to using! Even cell regeneration, has shown to occur only after a couple weeks of sober living. There is tremendous progress an addict makes during the moments of abstinence and sobriety. You shouldn't get too discouraged if you slip. Some failure is expected on the road to success. Abstinence, even attempted abstinence, brings power. If you relapse, don't give up, but continue to cultivate your capacity to get there. Furthermore, research shows that those who obtain long-term sobriety, actually relapsed at least 2-3 times. Think of recovery and treatment like climbing a hill. If you slip and fall, you don’t fall all the way down to the bottom, you just fall back a few feet, get up, and continue climbing. Once an addict is free from the drug of choice, they often experience increased feelings of depression and anxiety. Because relapse has been shown to be caused most by emotional states, successful addiction recovery needs to help an addict manage thoughts, emotions and moods. Negative moods and depression are common among recovering addicts because they are either related to the actual depressant effects of alcohol or drugs or to the losses experienced in one’s life (e.g., family, job, finances) as a result of using. Some people, however, continue to experience problems with depression even after they have been sober for some time. This is because the reward system in the brain has developed a defense mechanism after the long-term over-stimulation caused by drugs. When an addict quits, it is hard to immediately bounce back because the reward system is now under-stimulated. The reward system becomes under-stimulated following drug taking behavior because the brain decreases its natural production of neurotransmitters, making the reward center less-efficient. In such cases, it is vitally important to use methods that feed the brain through proper nutrients to keep neurotransmitter activity up. Website: http://truthofaddiction.com/special/ YouTube: http://www.youtube.com/user/TruthOfAddiction1 Facebook: https://www.facebook.com/TheOfficialTruthOfAddiction There are over 100 studies at MIT and Harvard that have confirmed that just using amino acids to increase neurotransmitters in subjects led to eliminating depression, cravings, anxiety and stress. The very states and emotions that have shown to trigger relapse. Nutrition combined with evidence-based techniques that change the brain is most beneficial. How to stop an addiction though evidence-based techniques. Treatment for addiction is changing and properly using methods that reveal how to stop an addiction before it gets out of control and how to help addicts in recovery is crucial.
