THis shit is not something you want to experiment with.
But if you must, be extremely careful! Don't do it alone. Start with a very small dose. 1/4 of a 100mcg/hr patch can kill a seasoned addict!
I had two close friends who have OD'd on fent & know of several others. This stuff kills.
And then there were the epidemic deaths that resulted from IDIOTS selling herion mixed with or that was actually fentanyl. Chicago, Detroit, New York City, Phili to name a few places where some dumbass(s) mixed the stuff way too strong. One sample I read about a few years back had 67mg of fent in one gram of "heroin". It was a while ago but I think they had like 100 fent fatalities over one summer in Detroit!
More recently there were 14 fentanyl / "heroin" deaths in one one month Pennsylvania county alone, three in a single day! >>see:

This is not fent extracted from patches but rather made in a lab somewhere, probably mexico where the precursor chemicals are not as difficult to get. The really stupid thing about it is that the fucking idiots of Nixon's DEA published the manufacturing process online! (that's where the citrate reflux method came from).
Just do a google search for "fentanyl heroin deaths" and you can always find that somewhere in the country there is always some city plagued with a bunch of dead addicts -Usually a bunch of young people 20-30 years old. What a fucking waste.
And if you want to really increase the danger, mix in some xanax or other benzo & some alcohol. My good friend of slipknot fame talked about fent and xanax being a recipe for "instant coma" as he handed me a couple dozen xanax and 10 fent patches from a fedex envelope he had just received. He was found dead in a hotel room three days later, on Bob Dylan's 60th birthday. And this was not a "novice" dope user. Still fucking haunts me.
Proves that even if you are a seasoned professional junky, this shit can kill you in an instant. All it takes is one small miscalculation or over-estimating your tolerance or capacity.
