You are correct. This is highly dangerous stuff, never intended to be cut, eaten, smoked, etc. Even the method advised by Mylan has caused accidental death. My son also had such a high tolerance he decided he would use all the methods I typed above. He had used opiates daily for approximately 8 years, with regular use of fent patches. He thought he was the shaman of his own habit because he had used this stuff so many times, every way possible. One day, he decided he would break open a patch and smoke whatever amount he had been doing for quite a while. Bad day. He over-dosed. Lucky we found him in time. Docs managed to resucitate him. When he became aware, first thing they asked him was why he tried to kill himself. He told them he'd been a user for years of the same amount and did the usual. He admitted to smoking it. They had taken his blood and knew the huge dosage. I'll never forget how this very large group of medical staff kept looking at him. It was a mix of horror, pity, disbelief he had survived, a "this person WANTS to die or is the stupidest man still breathing" look, a lot heads bowed down and head-shaking, non-believers in a god starting to believe, big, scared eyes even by trauma staff. These people see worst of worst all the time. The team who saved him were deeply disturbed with good reason. Anyone who does this is playing Russian Roulette each and every time, using drugs instead of a gun. They both do the same thing, and if you continue to play, eventually your bullet will come around and you will die as a result. I would not recommend messing with fent patches even to the most experienced, high-tolerance user. My son's bullet came around. Lucky for him there was gun failure and miraculously, it did not discharge.
