oral morphine can be very addictive, i became severely addicted to eating MSContin daily, i would go through over 200 morphine 30s in a week span, i would crush all them and mix with hot water on empty stomach with cofee...the euprohia was very similiar to heroin but a much milder feeling. not too many people enjoy morphine unless they were previous heroin addicts, in my experience with others. once you hit that suboxone maintenance stage, or MMT stage, it seems thebaine derived opioids just dont do the trick (oxycodone.oxycontin.opana) (hydrocodone.dilaudid), seemd only realy good heroin, or fentanyl or methadone would satisfy me once i went on maintenance drugs, plus most morphine pills are ER, which are abuse proof, so rying to IV them just gels up when you crush the pill and add water (sure there are methods to break thru the mechasnism, but im a junkie i dont got time or hours to do that. even with the instant release morphine sulphate 30mg pills, i had issues IVing, i would have to squirt 100cc of water over one pill, and another 50cc over it, just to stir and draw up a good 70cc of liquid morphine, still with leftover pill in the cooker. maybe sulphate isnt that soluble in water too much? word to the wise HEAT and morphine IR do NOT mix, it makes the solution thicker, i use ice water, and still banging a morphine 30mg IR, to me is a waste, sure i get a rush comparablew to 1-2 street bags of heroin, but its just not worth it, and snorting it i heard has an even lower BIO than oral, i learned to love morphine ORAL , unless its ampules like morphine hydrochloride meant for IVing..my tolerance is around where 80mg methadone would give me a good high, or taking over 400mg oxcycodone just keeps me straight without euphoria...with my tolerance in that range, 300mg morphine oral is strong enough to hit the spot and get me off...just cuz morphine has a poor oral bio doesnt mean shit at all, when i had a 15bag heroin day habit/400+ oxy daily habit, and went thru withdrawl for 1 week, i ate two 60mg mscontins, and got floored, to the point where i took too much, just 60mg would of got me nice..morphine is very potent and dangerous orally...dont let the 30% bio trick you..for example look at suboxone, its sublingual bio is around 33% itself, and 2mg or less can fuck someone up who has a heavy tolerance and took a few days off opiates...dont feed into the low oral bio bullshit ppl..
