When a person continues to take drugs, their brain will adjust by decreasing the capacity of cells in the reward circuit to respond to it. This will happen as long as the person continues to use drugs. This phenomenon, known as tolerance, has the effect of lessening the high that the individual experiences in comparison to the high that they had when they initially took the drug. They can try to attain the same high by consuming a greater quantity of the substance. Because of these brain changes, the individual frequently finds that they are unable to gain pleasure from other things that they used to love, such as eating, sexual activity, or social activities.
Long-term usage also produces alterations in other chemical systems and circuits in the brain, which can have an effect on a variety of cognitive and behavioural processes, such as learning, judgement, decision-making, stress, memory, and behaviour. Due to the nature of addiction, many people who use drugs continue to do so despite the fact that they are aware of the potentially negative consequences of their behaviour.
Why do some people develop a tolerance for drugs while others are able to avoid this fate? There is no one characteristic that can reliably forecast whether a person would develop a dependency on drugs. The likelihood of developing an addiction is determined by a number of different factors. The more predisposing characteristics a person possesses, the higher the probability that using drugs would result in addiction to those drugs.
Biology. About half of a person's propensity toward addiction is determined by the genes that they inherit from their parents. Other factors that may increase the likelihood of drug abuse and addiction include gender, ethnicity, and the existence of other mental problems.
