Drugs or alcohol can be addictive since people are addicted either emotionally, socially or biologically. Most individuals use drugs or alcohol due to their curiosity, friends pressure, stress, anxiety, depression, or personal issues. Substances alter the reward system of the brain, which allows chemicals to make a person be happy and relaxed in the short-term. Over time, the brain begins to be addicted to these substances leading to cravings and difficulty to quit. The environment, previous trauma, and genetics may as well increase the likelihood of addiction. Good counseling, therapy and support are capable of making the people overcome addiction and begin a healthier life.
