In most cases, the administration of heroin leads to a high that lasts for a few hours and peaks around two hours after being taken. Upon entering the brain, heroin is converted into morphine. This morphine binds to opioid receptors in the brain that provide perception of pain and reward. Heroin also affects areas of the central nervous system that control automatic bodily functions such as blood pressure and respiration, which can lead to slowed breathing and heart rate.


How long does a Heroin binge last?


Regular use of heroin causes significant changes in physiology and brain chemistry. The body quickly builds a tolerance to heroin so that it takes more and more of the drug to experience the same effects and reformats the brain to be psychologically urged to use the drug despite negative life consequences. It will eventually lead to marked changes in behavior, personality, and psychology.

Heroin’s effect and duration depend heavily on the method of administration. While injecting and snorting heroin are the most common ways to take the drug, it can also be ingested or smoked. Intravenous use of heroin onsets effects in around twenty seconds and lasts around four hours, while smoking heroin takes ten minutes to kick in and peaks for five, tailing off for around five hours.

Heroin causes intense euphoria and a subjective rush of vitality, as well as an increase in body temperature. The euphoria operates on a spectrum and may last from 45 seconds up to several minutes. The most intense peak effects may last up to two hours and the overall sensation takes  around five hours to dissipate, and results in feelings of drowsiness, disconnection, and disassociation from the world.

Upon administration, users feel nausea followed by a “hit” or “rush,” which may last ten to twenty minutes depending on the user’s tolerance to the drug. During this period, the user may experience a strange sensation in which the body feels as though it is made of liquid and radiating heat from the inside, making the skin red hot. When this effect wears off, the body begins to feel heavy and intense dizziness settles in for anywhere between thirty minutes and two hours. The final stage of heroin use varies drastically between users.

Heroin introduces physical detriments to your health with continued use. Problems with defecation and sex drive emerge, breathing becomes shallow, and concentration, perception and cognition are all affected. If heroin has been injected, users may feel a burning and itching sensation on the skin. Users new to taking heroin may vomit or feel nausea.

Following the rush, users have difficulty breathing and may enter an intensely alert state or latent sleep. The heart rate becomes irregular an unregulated. When tolerance is developed and more of the drug is taken, an overdose can occur, leading to unconsciousness, coma, or death.


Heroines must be avoided and users should seek out medical help if they have become addicted. It is a cruelly unforgiving and extremely dangerous substance that tears apart families and can certainly lead to death.
