Depends, do you want to relieve pain, or get high. Note that some people don't have the enzymes to break down codeine into morphine so codeine will have no effect on them, others have less enzymes or...
yep codeine gets you high. you may not like the guaifenesin though.. lol has a lot more of that than it has codeine but yes it will deffinately get you a codeine high depending on the dosage
