Answer: C - The two main models used in understanding drug abuse and addictions are cultural and biological.
Key Takeaway: Drug abuse and addictions are currently explained using two models: cultural and biological. The cultural model holds that exposure to addiction at home or the general environment is an important determinant of drug abuse and addictions. The biological model holds that exposure to drugs, for example, changes the way the brain functions and deals with external stimuli. This leads to the person developing a dependency on the drug because of this change.
