First off, my tolerance to get high is approximately 30mg Oxycodone, which is equivalent to about 45-50mg of hydrocodone. I have access to both 75mcg Apotex and Mylan fentanyl patches. I've tried using 1/4th of the Apotex patches by putting it in my mouth buccally, I don't chew it. The duration I kept it on for was about an hour and a half. That amount would barely get me buzzed. I looked up and did some research online and many other people agreed and said that Apotex patches were indeed garbage. I've now gotten access to Mylan 75mcg fentanyl patches and am looking for advice on how to use them safely. I did an online opiate conversion from 30mg Oxycodone to fentanyl trans dermal and the conversion said 12.5mcg. 75mcg divided by 12.5mcg is 6, so that would mean I cut the patch into 6 pieces which would mean 6 times of buccall use. I'm looking for advice and feedback on what the difference between the Apotex and Mylan patches will be, and whether I should just go straight to 1/4th of the Mylan or to cut it back to 1/6th, or maybe even 1/8th as I've never dealt with the Mylan and don't know how much more potent they will be buccally. I'm also wondering what the difference is between buccall use of a fentanyl patch and the difference between chewing a patch. Thank you in advance for the advice and feedback!
