They are synthetic compounds introduced into medicine to produce an anesthetic loss of sensation without depressing respiration and cardiovascular function as do the general anesthetics. These drugs are called opioids partly because they activate the opioid receptors on nerve cells, mimicking the effects of pain-relieving chemicals that would otherwise be produced naturally. The number of pumps that participants take is used as a measure of their tolerance for risk. are all psychoactive drugs. The brain will then stop functioning as it did before introduction of the opioid, causing levels of dopamine to drop when the drug wears off. Calming effects, sleep, pain relief, slowed heart rate and respiration, Impaired judgment, loss of coordination, dizziness, nausea, and eventually a loss of consciousness, Sluggishness, slowed speech, drowsiness, in severe cases, coma or death, The chemical makeup of opioids is similar to the endorphins, the neurotransmitters that serve as the bodys natural pain reducers., Slowing of many body functions, constipation, respiratory and cardiac depression, and the rapid development of tolerance. Low-tolerance people tend to make a few pumps and then collect the money, whereas more risky people pump more times into each balloon. On the other hand, drugs that are normally associated with addiction, including amphetamines, cocaine, and heroin, do not immediately create addiction in their users.

Rave drug (not Ecstacy), also used as a date rape drug. central nervous system, system of nerve tissue in vertebrates that consists of the brain and spinal cord. Some people might also have altered senses, for example, seeing brighter colors. The most common psychoactive drugs can roughly be divided into four groups: Depressants, such as alcohol, sedatives/hypnotics and volatile solvents, that diminish the activity of the central nervous system.

Hallucinogens can alter a persons senses and cause them to see or hear things that are not there. Drugs can be categorised by the way in which they affect our bodies: depressants slow down the function of the central nervous system. As a result, fluid builds up in the brain. First of all, cocaine stimulates the release of dopamine into the empty spaces between neurons, essentially flooding the brain with this neurotransmitter. However, the physical effects of heroin, such as a slower heart rate and reduced breathing, may sometimes be life threatening. This means that they speed up the central nervous system, increasing heart rate, body temperature, and blood pressure while increasing energy levels, focus, attention, alertness, and wakefulness.

For these reasons, stimulants are frequently used to help people stay awake and to control weight. Scientists have always assumed that all opioidswhether produced by the body (endogenously) or taken as a druginteract in the same way with opioid receptors.
