Just a little update. I did a 2.5mg IV shot with no ill effects, felt AMAZING and awhile after (about 2 hours) passed peacefully asleep. Obviously bigger doses around 7-10mg doses could be kinda dangerous. Depending on tolerance, it could put you to sleep very quickly if IV'd, as well as possibly cause respiratory depression. If someone does this (larger doses IV'd, have a sitter just in case), be careful.
