A is correct
Step-by-step explanation:
A long-term benefit of quitting a dependence on drugs is a) increased ability to sustain relationships. This benefit is due to improved mental health, emotional stability, and the return of trust that often deteriorates in the midst of substance abuse. Drug dependence can negatively impact relationships due to changes in behavior, priorities, and the social isolation that often accompanies addiction. Overcoming addiction allows individuals to rebuild these important social connections and contributes to a more stable and fulfilling personal life.
Quitting drug use also brings about several other health benefits, such as a reduced risk of developing chronic diseases, improving mental clarity, and enhancing overall well-being. For example, by one year after quitting smoking, the risk of heart disease drops to only half that of a continuing smoker. This illustrates how cessation leads to immediate and significant health improvements.
