Researchers will always need to balance making information simple and accessible for policymakers and the public with the inherent complexity of drugs and their effects. This makes the task of building scientific drug policies very challenging.

If you’re worried about your substance use and think you might be at risk for a substance use disorder, the best thing to do is to seek help and information, says O’Neill. “There are many counselors, coaches, and support group meetings that can help you understand and learn more about it. Treatment involves a professional assessment and treatment plan to meet the person’s individual needs for sustained recovery, says O’Neill. "The treatment plan can vary depending on several factors, such as severity of use and the person's resources and sources of support." Previously, the term ‘substance use’ was meant to describe mild use of a substance, and the term ‘substance abuse' was used to describe moderate or more severe use.

For the brain, the difference between normal rewards and drug rewards can be likened to the difference between someone whispering into your ear and someone shouting into a microphone. As a result, the person's ability to experience pleasure from naturally rewarding (i.e., reinforcing) activities is also reduced. Other drugs, such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals by interfering with transporters. This too amplifies or disrupts the normal communication between neurons. Both disrupt the normal, healthy functioning of an organ in the body, both have serious harmful effects, and both are, in many cases, preventable and treatable.
