Answer:
True.
Step-by-step explanation:
Addiction is a physical and psychological condition caused by the constant consumption of chemical and / or psychoactive substances (such as medicines and drugs). Due to the constant use of these types of substances, the human body becomes increasingly dependent on them, resulting in symptoms that affect the nervous system.
Addiction makes people's bodies get used to the dosage and does not produce the same effect. With this the dependent person will increase the dosage of the substance to be able to feel the same sensation that felt with the lower dosage.
