I/GCSE Biology - Drugs

Drugs

· biology,IGCSE,igcse biology,drugs,gcse biology

For drugs to be safe, they must be tested. Legal drugs are tested over many years and must pass several stages before approval.

Drugs testing

  • Allows us to know what the drug can be used for
  • Allows us to know any side effects
  • Allows us to know which medications or other drugs they interfere with
In I/GCSE, drugs are split into categories depending on how dangerous they are.

The three main categories

Class A

  • Highly dangerous, illegal drugs

Class B

  • Dangerous, illegal drugs
  • Possession and dealing are illegal and there is no reason for anybody to use it
  • If you are found with the drug, you could face a prison sentence

Class C

  • The drug is allowed to be handled by people with a licence to dispense
  • Anybody in possession must have a medical reason and a prescription
  • It is illegal to possess the drug without a prescription or dispense the drug without a licence
Some drugs examples

Cannabis

  • Currently a class B drug
  • At the moment, there is no legal reason for anybody to be in possession of it
  • A common drug which has many side effects, especially the new, stronger version known as ‘skunk’

Heroin

  • A dangerous drug
  • Known as a depressant
  • Slows down the heart rate and gives people a feeling of ‘high’
  • Allows users to escape reality

Cocaine

  • A stimulant
  • Affects the heart and CNS

LSD

  • A hallucinogen
  • Affects the brain
  • Has long term effects which can lead to paranoia and disturbing hallucinations

That's the end of today's topic!
