First off you don't need to use SWIM on bL, actually it's against the BLUA found in my signature below. Our take is that it offers no legal protection, and makes posts harder to read.
Secondly there is truly no safe method to IV morphine sulfate er due to the gel matrix that has been added, making it far more dangerous than IV pills in general (which is still a quick way to mess up your veins). If you're considering this, I strongly advise plugging them instead.
As to the thread in general, we aren't here to help get you high, rather keep you safe, which is the reason I'll leave this open. Not trying to sound harsh as I know you're new to the site, just pointing out some differences from other forums you may have posted on.
