Ya, I mean wouldn't reccomend it but, if you know what your doing, know the risk etc, I don't see the big deal, and it can't be as bad as people who shoot there cherry red methadone take homes.... and really if its strips,don't know the inactive ingrediants(know citric acid,think white ink for the little N's on it,and something else) in it but they gotta be betther that what people shoot black tar with...Now I know people always say micron,micron,micrion(i agree) but they really every only mention with pills..Not Black Tar Heroin or Street Cocacain..If you wanna keep your veins those are two street drugs you should defineately micron filter, don't know how many times I've heard Tar destroyed someone's veins...
EDIT: Inactive ingredients-polyethleyne oxcide,hydroxproypl methycelluose,maltitol,acesulfame pottasium,citric acid,sodium citrate, FD&C yellow 6, and white ink for those lil n's on there.
