Psychoactive drugs can increase or decrease transmissions to post-synaptic membranes. Excitatory drugs can mimic the action of neurotransmitters or delay the breakdown of neurotransmitters. On the other hand, inhibitory drugs can hyper-polarize the post-synaptic membrane or reduce the effect of excitatory neurotransmitters.
Generally speaking, they short out the brain. Chemical reward systems are activated whether or not they "should" be, for some drugs. LSD really messes up the functioning of the brain.

A substance that does not affect the brain or cause changes to mental processes. Examples include non-psychoactive hemp (for snorting), diet pills, and antibiotics.
Psychoactive drugs affect the brain, which is a part of the nervous system.
Excitatory psychoactive drugs such as nicotine and cocaine primarily affect the central nervous system. They increase post-synaptic transmissions and may result in addictions and substance abuse. These stimulants increase the alertness of the user by mimicking the action of neurotransmitters or delaying the breakdown of neurotransmitters. They can also affect the transmission of optical signals in the thalamus of the brain.

A psychoactive effect is an affect on mood or behavior caused by the misuse of drugs.
Journal of Psychoactive Drugs was created in 1967.
Drugs that affect the central nervous system causing mental or behavioral changes are commonly referred to as psychoactive drugs. These drugs can alter mood, cognition, perception, or behavior when taken. Examples include stimulants, depressants, hallucinogens, and opioids.
They have been on psychoactive drugs since day 1.
like that.
Psychoactive drugs or psychotropic medications are substances that alter brain function to alleviate the symptoms of mental dysfunction. These drugs may target neurotransmitter activity in the brain to regulate mood, cognition, or behavior.
