same here, I've been using(abusing) Pharma grade morphine ampoules for 7 years. And nope, no dmg to my veins whatsoever, even when i inject everyday multiple times a day, nothing happens to my veins, they are still thr same. ? ? ? On topic:you seem to have a needle fixation, when i had to quit morphine for obvious reasons(i was broke, my tolerance was through thr fking roof, i was wding after every 12" hrs of my lsst dose) it wssnt sustainable anymore. it never was actually, but somewhat like u, i had a needle fixation, i loved the instant gratification that comes with thr needle. So i tried to replace Morphine with ketamine. That didnt go so well, ket is not a drug for me, its so dirty imo. Thats when i began to dhoot up Cocaine and that's when my demise began aswell. Dont wanna go into too much detail but that drug through that ROA almost destroyed me. Had to go to rehab multiple times otherwise id be dead. Anyways yeah, its common for ppl to associate the needle with pleasure, it is In fsct the most addictive pathway to grt high yo. Cheers, NZN
