How Drugs Affect You

How a drug affects a person depends on several factors:

  • Drug factors (the drugs’ pharmacological properties; its impact on the central nervous system)
    • How much is used (and its potency or strength).
    • Risks might vary depending on whether the drug is used via oral ingestion, smoking, inhaling, injecting.
  • Individual factors such as:
    • the person's sex (e.g. the same amount of alcohol affects men and women differently)
    • the person's health
  • Environment or context in which the drug is used
    • drinking alcohol on an empty stomach immediately prior to work or driving a car carries different risks compared to drinking at home with a meal
