What is the dependence on opioids?
opioid dependence is a disorder of dependence characterized by systematic abuse of opioid analgesic drug. The most commonly abused opiates are the following drugs: heroin, oxycodone, hydrocodes, morphine and codeine. Heroin is the most commonly abused opiate drug in the world, mainly because of the intensive euphoria it produces. Chronic abuse of one or more of these substances leads to physical dependence and psychological dependence. Opiate analgesics can be smoked, snorted or injected. For example, if he inserts heroin daily for a permanent time, he is likely to experience intensive symptoms of physical collection when the drug is stopped. Typical symptoms of physical abstinence include nausea, vomiting, diarrhea, stomach cramps, muscle pain, insomnia, fever, suicidal depression and anxiety. The above symptoms of physical collection are vital to all forms of opiate analgesics, with different degrees of severity.
As far as the biochemistry of opioid addiction is concerned, the main reason is the drugs of opiates highly addictive, that they bind to opiate receptors in the brain. These receptors are designed for a molecule known as endorphine, which increases feelings of pleasure and reduces pain feelings. When administering opiates of the drug mimics the effect of neurotransmitter endorphin and creates an intense feeling of euphoria. When a person uses opiate medicine for a long time, the brain stops producing endorphins because the receptors are overloaded with opiate drug. Therefore, when one stops using opiate such as heroin, lack of endorphins and absence of opiate, it will bring very painful withdrawal symptoms.
One of the more serious forms of opioid dependence is long -term Heroin Addic. Long -term heroin dependent is afraid of experiencing the above withdrawal symptoms and going to almost any lengths to obtain a medicine. Long -term heroin addict usually uses a medicine to feel "normal"And avoiding download. Some addicts have heroin habits up to $ 500 (USD) daily, in which case it can be limited to theft, drug trafficking or raising funds through drug prostitution. Developed countries have introduced programs of medical treatment for opioid addictions for addicts who want to recover, including programs in which an addict is prescribed methadone, which helps with symptoms of abstinence.
