Drugs Trial – Science

Drugs produced from plants:

  • Opium poppy (heroin, morphine, codeine)
  • Blue agave (Tequila)
  • Coca leaves (cocaine)
  • Ephedra sinica (Sudafed, meth)
  • Psilocybin mushroom (shrooms)
  • Willow bark (aspirin)
  • Sassafras root (ecstasy)
  • Penicillium mold (penicillin)

Drugs produced by microorganisms:

  • Antibiotics
  • Penicillin
  • Alkaloids

New drugs developed always need to go through several test before they are prescribed to patients and revealed to the public. The tests are done so that scientists know that they are safe, any side effects and if the drugs have a positive affect on the patient. The drug will first be used on human cells in a laboratory. If passed it will then be tested on animals, which brings about a lot of controversy. Animals are tested on as they have similar DNA as humans. Animals such as monkeys, apes and mice have really close DNA to humans. If the drug is seemingly safe on the animals and side effects are noted down along with appropriate doses, it will be used in a clinical trial. Clinical trials are where the drug is used on healthy volunteers with very small doses, to guarantee if the drug is safe. Further clinical trials are done later. Sometimes drugs may go through all the trials until the clinical trial where it shows to be ineffective or result in serious side effects and then will need to be scrapped.
