I have the most frequent urges with cocaine; that almost goes without saying. From my experience though the cocaine comedown from IV has been much milder than when I was snorting coke.deva said:so may i ask which you find more addictive..... booting coke or meth or opiate? specifically, which one do you find the most need to redose asap on? i've never IV'd anything, and probably never will (just a personal thing i guess) but i found when snorting coke, i found the urge to redose within minutes, and REALLY strong urges to redose when effects starting to wear off.
