  1. what is a placebo

  2. give an example of a legal reacreational drug
    • tobacco
    • nicotine

  6. explain why a person might become addicted to a drug
    • drugs contain addictive chemicals for example a cigarette contains nicotine
    • drug alters the body's chemistry
    • causes withdrawal symptoms if the person stops taking the drug
    • they feel they need more of the drug to get the same effect as they used to do when they were taking less of the drug
  7. why might data from a drug test be more reliable than other data from the same test
    because some tests may have a higher number of participants
  8. when asking which drug was most effective the drug that is most effective may be most effective ans you can tell this because there the biggest
    difference betweeen the placebo and the treatment
  9. in phase 1 testing healthy volunteers are used rather than patients
    suggest a reason for this
    • the dose may be too low to help patients
    • higher risk for paatients
    • the drug might conflict with patients treatment
    • might conflict with the other drugs the patient may be on
    • effect of the drug may be masked by the patients symptoms

    • anabolic steroids
    • increase heart rate
  20. steroids can cause
    high blood pressure
  21. some performance-enhancing drugs are
    banned by law , some are prescription only , but all are banned by sporting bodies
  22. what are the ethical problems against taking perfromanec-enhancing drugs
    • it's unfair if people gain an advantage by taking drugs , not just through training
    • athletes may not be fully informed of the serious health effects of the drugs they take
  23. what are the ethical arguements for taking performance-enhancing drugs
    • athletes have the right to make their own decision about whether taking drugs is worth the risk or not
    • drug-free sport isnt really fair anyway because different athletes have acess to different training facilities , coaches , equipment , etc
  24. claims about drugs need to be
    looked at carefully
  25. statins are prescribed drugs used to lower the risk of
    heart and circulatory disease
  26. there's evidence that the statins lower blood cholestrol and
    significantly lower the risk of heart disease in diabetic patients
  27. the origional reseacrh for statins was done on by government scientists with no connection to the manufactuers . The sample size was big with over 6000 petients . It compared two groups of pateints - those who had taken statins and those who hadnt . Other studies have since backed up these findings so
    control groups were used and , and the results were reproducible so statins can be proved to be effective at lowering heart and circulatory disease
