Yes. Codiene, as an opiate can cause pupil constriction. This usually only happens at higher, recreational doses.
Yes, all opiates will.
no
no, uppers, acid & ecstacy will dialate your pupils. downers, like heroin and oxy's will constrict "pinpoint" your pupils
yes, as will all opioid medications and/or substances
No, historically it's the exact opposite, it causes dilation of the pupils, particularly in larger than therapeutic doses. If you're noticing constricted pupils despite being on this medication, I would recommend notifying your doctor immediately as there may be another cause.
No. It actually dilates them. Opiates (hydrocodone, heroin etc) constrict pupils.
Pain killers, in general Opiates. Also recent recreational opiate use (e.g. heroin). Sometimes diazepam can cause this as well, among other prescription meds.

My eyes do it looks like I'm taking heroin
Can steroids cause pupils to dilate
Smoking heroin can severely affected the body. It can cause shallow breathing, constricted pupils, nausea and possible vomiting. It can also affect the nervous system causing drowsiness, coma and even death.
Codeine creates hallucinations that can enhance colors or make you think you see things moving. I don't suggest taking a lot of codeine and going out anywhere. It creates major paranoia and can leave you very anxious and confused.
The drugs that most commonly cause constricted pupils or "Pinpoint" are strong opiods such as Heroin, morphine, oxycodone, or high doses of norco / vicodin.
