Final answer:
Social influences like being raised by substance abusers, social isolation, low parental education, and past mistreatment increase the risk of drug abuse. Environmental availability and norms regarding psychoactive substances, alongside the development of addiction and dependence, further contribute to substance abuse.
Step-by-step explanation:
There are several social influences that can increase the likelihood of drug use or abuse. These influences include the environment a person grows up in, such as being raised by substance abusers, which significantly increases the risk of both physical abuse and neglect. Other factors contributing to the increased risk of drug use include social isolation, depression, low parental education, and a history of mistreatment in childhood. Furthermore, the availability and norms around legal and illegal psychoactive substances play a significant role in potential drug addiction and abuse. Addiction is defined as the compulsive use of a substance despite negative consequences, and dependence may develop over time, leading to withdrawal symptoms upon cessation of use. The use of drugs without medical advice or for reasons not initially intended, especially when continued, may lead to addiction, which can culminate in increased tolerance, overdose, and even death.
