The Effects of Heroin
The effects of heroin are almost identical to those of morphine. Like morphine, the effects of heroin are strongest on the central nervous system; only heroin is both faster and stronger.
Once inside the bloodstream, the effects of heroin are produced by heroin imitating the action of endorphins. In this way, the primary effects of heroin are a sense of euphoria and what many users describe as an ‘orgasm in the gut’. Furthermore, once inside the brain, heroin is quickly metabolized into morphine.
Effects of Heroin
In like manner, heroin is also converted into morphine when the liver metabolizes it. The gastrointestinal effects of morphine, for this reason, mimic those of morphine, and can cause severe cases of constipation. Often, when the effects of heroin have worn off, users will feel an intense, undeniable urge to use the toilet.
Effects of heroin on the cardiovascular system are also similar to the effects of morphine and other opiates in that they may cause arrhythmias, noncardiac pulmonary edema, and other adverse effects on the heart.
The effects of heroin and the rapidity, with which they are felt, are dependent on how it is taken. If heroin is taken orally, the effects of heroin are virtually the same as morphine. If smoked, the effects of heroin are felt almost instantaneously but results in a milder effect (which gets stronger the longer it is used). When snorted, the effects of heroin can be felt within 10 to 15 minutes; and when taken via intravenous or intramuscular injection, the effects of heroin are with within 7 to 8 seconds, and 5 to 8 minutes respectively.
As a result of the strong effects of heroin on the body, in particular the central nervous system, heroin is the most addictive of all narcotic analgesics.
