Welcome to Bluelight!
And for the record, we don't do the whole "my friend needs help" or "this person who isn't myself" thing. In fact, it is very frowned upon.
You can put the pouch on your body (top of arm is best but I wouldn't recommend putting the whole patch on unless you have a quite high opiate tolerance), cut it into small pieces and put it in between your gums and chew on it occasionally. Or if it is the right type you can carefully extract the gel and smoke small bits of it on foil, but this is dangerous and I wouldn't recommend it.
Fentanyl is a very very powerful opiate that should be handled very carefully. A lot of people overdose on this drug due to being un-educated about it's strength. Start off small.
