“Just 2 to 3 milligrams of fentanyl — equivalent to five to seven grains of table salt — is enough to cause respiratory depression, arrest and possible death”

A Police Officer had an OD from brushing his uniform off, not knowing the white powder was fentanyl, earlier this year.

Also, there are varying grades of fentanyl. Some of the OD cases in the Akron area involved heroin laced with a strength of fentanyl used to sedate big game (think elephants and giraffes) before surgery.

And .02 or .03 mg of carfentanil could be fatal.
