Effects of Drugs

Law of effect

Everyone is different. Each person’s body and mental state, the product he or she uses and the context in which it is used influence the overall experience. These elements combine to form the ‘law of effect’.

The law of effect is the result of a combination of 3 factors:

  • The individual
  • The context in which he or she consumes
  • The product or substance being consumed

Each of these 3 factors is linked to different characteristics.

Each time a characteristic associated with one of the factors is modified, the effect of the drug on that person also changes.

Characteristics of the factors of the law of effect

Here are some examples of characteristics associated with the factors of the law of effect:
