What is heroin use?

Heroin is an illegal drug that is highly addictive. It's an opioid, like some types of medicines that doctors prescribe to treat pain. Examples include hydrocodone, oxycodone, and morphine. These medicines have rules for legal use. Heroin does not. There is no quality control. The strength of each dose is not known. It's often mixed (cut) with other drugs like fentanyl or things like powdered milk. It may also be cut with poisons, such as strychnine.

Often, heroin use starts with the misuse of a prescribed opioid. A person may then switch to heroin because it costs less, in spite of the greater danger of using it.

A person who uses heroin often will start needing bigger and bigger doses of the drug to get the same effect. This is called tolerance. If a person uses heroin regularly, the body gets used to it. This is called physical dependence. This leads to withdrawal symptoms within a few hours if the person stops using it or uses less.

Someone who uses heroin daily can become addicted to it within a few weeks. Addiction means that the person has a strong need to keep using heroin even though it causes harm to themself or to others. Heroin addiction is also called opioid use disorder.

Heroin overdose and rescue treatment

Using heroin can be dangerous. An overdose may cause trouble breathing, low blood pressure, a low heart rate, a coma, or death. It's hard to know how much heroin can cause an overdose. A lot depends on how strong the drug is and what it's cut with. And if a person starts using less heroin, they may lose tolerance to it. The person may be at a higher risk of overdose.

If you or someone you know uses heroin, talk to your doctor or pharmacist about a naloxone rescue kit. Naloxone is medicine that may reverse the effects of heroin if given soon enough after an overdose. Having a naloxone kit may save a life.
