The effects of drugs on the nervous system vary from person to person and depending on which drugs are being abused. Short-Term Effects of Drug Abuse on the Nervous System People become addicted to drugs because intense messages of pleasure are rapidly released by the nervous system into the brain. As drugs enter the nervous system, they affect which messages are being sent as well as their transmission rate. The pleasure centers of the brain, which receive neurotransmitters like dopamine, are affected by drugs of abuse, no matter which type of drug they are. Hallucinogenic drugs distort the messages sent between neurons, leading to the psychedelic high that many people experience while on hallucinogens. CNS depressants, such as alcohol, slow them down. These drugs are well-known to impact the CNS:ĬNS stimulants, such as cocaine, speed up the transmission of messages sent throughout the body. The CNS, in particular, is impacted by drug use. Protecting neurons and neurotransmittersīoth recreational drugs and those prescribed for medical reasons impact the nervous system.The nervous system performs these additional functions: Together, the CNS and PNS transmit messages throughout your body that instruct you to do essential functions, such as breath, move, see, smell, and think. The nervous system is comprised of two main systems that run throughout your body: the central nervous system (CNS), which is made up of your brain and spinal cord, and the peripheral nervous system (PNS), which includes all of the nerves that extend from the spinal cord to the rest of your body. It can impact neuron transmission, cause nerve and tissue damage, contribute to brain damage, and reduce the functioning of vital organs. Long-term drug abuse can impede proper functioning of the nervous system. In the short term, drug abuse can cause the nervous system to speed up or slow down the transmission of vital messages between your brain and the rest of your body. Drug abuse greatly affects one of the most vital systems in your body: the nervous system.
