With the ability to change the brain's functionality, they quickly alter mood, perception, and consciousness. It is not certain exactly how these drugs work in the brain; however, it is largely understood that they interrupt normal communication between neurotransmitters. Opioid drugs also disrupt the natural production of norepinephrine and act as central nervous system depressants. If you believe that you or someone close to you is showing signs of addiction, you can contact the following organizations for immediate help and advice: Psychoactive drugs alter the way a person thinks, acts, and feels. Impaired coordination, learning issues, and sleep problems can result from long-term marijuana use and its impact on the brain. Overview of effects Stimulants, such as nicotine, cocaine, amphetamines and ecstasy, that increase the activity of the central nervous system. For instance, the prescription drug Chantix acts as an antagonist, binding to nicotine receptors in the synapse, which prevents users from receiving the normal stimulant effect when they smoke. Robins, L. N., Davis, D. H., & Goodwin, D. W. (1974). Alterations of moods, distortions of reality and sensory perceptions, and seeing, hearing, or feeling things that are not there are common side effects of drug-induced psychosis, or a trip.
