If low tolerance to opioids and being a raging opiate junkie in general than morphine will be peak opioids for some in the beginning.
The tablets of morph had insane euphoria lasting all day and more in the beginning b4 tolerance rose and killed it lol. Morphine gives me constipation like none other so I try to avoid it lol. Also morphine comes with an itchier fit than the rest I think... don't scratch urself crazy in public if you don't want good stares from many around you on it.
Morphine sucks in time even if IV'd and all.. Its just not worth it LOL. There's not really anything good besides pain relief that is going to come out of morphine lifestyles XD
