Duragesic - these are very good... it's fentanyl in a transdermal system - your friend probably means 100ug/hr (or 10mg) patches - thats 100 micrograms every hour to the user... the patches come in 25ug, 50ug, 75ug, and 100ug strengths and last 72 hours according to the package, or about 50 if you want my honest opinion (then again, after the first 20 hours the rest is a blur) ..
For best use, simply read the instructions that accompany the package - then do the oposite .. shave the area of your body where you're going to apply the patch - I recomend the upper-arm, over your heart, or upper back .. they will fall off, so it helps to cover your patch with a large band-aide.. rub it for a minute or so after putting it on, as this gets the drug flowing, but it can take several hours before the drug actually kicks in - the 50ug and 100ug patches ARE intense and will keep you busy for an entire weekend, they can also make driving a chore and even with something of a narcotic tollerance, a 100ug patch had me nodding rather hard .. a few passes with a hot blow-dryer also make a noticible improvement for short periods of time..
EDIT - as for the cost, they usually go for $10 a mg, so a 100ug/hr patch would sell for $100 ..
