Synthetic opiates have been produced; examples include meperidine and . Opiates are often referred to as narcotics. These drugs bind to opiate receptors found throughout the central nervous system which cause the release of endorphins, the bodies natural opiates. Ounce the opiate receptors are filled and endorphins have been realized long lasting euphoric feeling, usually accompanied by a very happy, comfortable feeling. The affects of opiates last for a relatively long time, and aren't followed by as a severe period of depression and tiredness.
Opiates have many medical uses as sleeping aides, pain relievers, stress relievers, and even cough medicines, because they numb the nervous that cause the coughing. Certain types are available without persecutions but these are extremely weak versions of the drugs. When under prescription these drugs are usually given in pill or syrup form, for some sever cases they are giving intravenously though. The illegal versions are often simply prescription drugs sold with out prescriptions, but other forms of illegal opiates are made just for the purpose of drug sales. Opiates are CNS depressants so they shouldn't be taken with other CNS drugs, or with any other depressants.
When under prescription overdoses are rare as long as the directions are followed, but when opiates are taken for the purpose of pleasure overdoses become a risk. It is hard to tell when some has overdosed and the best way to prevent it by not taking any other drugs while taking opiates. Overdose symptoms include slow shallow breathing, very clammy skin, and convulsions.
