so i blew a new mallinckrodt oxy 30 IR (not a high amount at all for me) and a half hour later i get a terrible headache. i later read something about whether these things might have an anti abuse mechanism on them that makes the user get headaches and stomachaches. right now, my breathing is a little shallow. does anyone have any experience with this?

No the Malli 30mg dont have any anti-abuse. The Generic OCs that malli makes will gel, but they wont make a pill that makes you sick without a warning first. They would be sued and shut down if they didint.

friendly bumparino neighbors!

I don't have any experience with this, but i can tell you I've seen it done with other pharms. Hydrocodone for instance, at least when sold as Vicodin, contains relatively large amounts of acetaminomorphen in order to dissuade potential abusers from taking too much. Past a certain amount, their livers will just go into a hellish overdrive to purge the body of the acetaminomorphen and basically ruin whatever the intended effect was on the part of the abuser.

Like I said the Malli 30s dont have any anti-abuse in em. I have done litterly thousands of them.

May just be a filler or binder that doesn't do well with you. Opiates and opioids can cause headaches sometimes.

acetaminomorphen

lol naw I don't think thats his problem
