a codeine based painkiller that is available on prescription, contains 500mg paracetomol 30mg codeine, they make you feel super groovy for a couple of hours, also they are addictive i take 4 at a time and i spend all day fucked out my mind, they also constipate me so i take like 1 shit a week then after about a month of that your belly gets swolen and ur arse will eventually collapse completely. they really are a fun recreational drug.
