Overdose amount: 75-500 milligrams depending on body weight. Because the purity of illegally obtained heroin varies wildly, always start with a low dose, and keep nalaxone on hand if you're able.

Class: Opioid

Standard dosage: These doses won't mean much unless you have a bottle of hospital grade diamorphine, but there is no better dosage information to give because of the varying purity of heroin sold. So when using heroin, it is even more important to always start with a low dose than it is with other substances.

• Smoked: 2-20 milligrams 
• Snorted: 5-25 milligrams
• Injected: 1-8 milligrams

Notes: You can die from mixing with alcohol, benzodiazepines, or other depressants. Mixing with stimulants increases the risks that both substances present. The purity of heroin varies wildly. There is no real way to tell how pure any heroin is unless you got it from a hospital, so always start with a very small amount to avoid danger. Remember that regardless of tolerance or intoxication, the overdose amount remains the same. Heroin is often cut with Fentanyl which is much easier to overdose on.
