Addiction
Addiction is a condition of the brain's reward system that develops through transcriptional and epigenetic pathways and takes place over time as a result of persistently high levels of exposure to an addictive stimulus (e.g. eating food, the utilisation of cocaine, engagement in sexual intercourse, participation in high-thrill activities such as gambling, etc.). Substance abuse or drug addiction and behavioural addiction, such as a gambling addiction, are the two categories under which it is classified. People who suffer from depression or other mental health conditions are more vulnerable to alcohol and drug abuse. In addition, anxiety and depression are frequently found in drug addicts along with other mental illnesses. Some people use drugs or alcohol to relieve stress or intense suffering, but doing so repeatedly can worsen or worsen mental health.
