How much of an Opioid can be Deadly?

Because different opioids have different strengths and each person has different metabolism rates and tolerance levels, it is unpredictable how much is too much to cause an overdose.

Equivalent doses

It is important to remember that overdoses often take place because users do not know what substances are cut into their drugs. Fentanyl is most commonly found in the drug supply, but it is often mixed with other drugs and fillers.

While someone may think they are only taking fentanyl, it could be mixed with other potent substances, therefore increasing their risk of an overdose.
