Is this a serious question or some kind of sick joke? This is a professional forum and admitting to a commission of a crime here is absurd. How this was allowed to be posted without review is crazy. If this is in fact a serious question, I think your biggest concern should be how your going to handle CPS & the State removing your son from your care for admitting that you willingly gave your son illegal drugs to sale at his middle school for business!!!
Bottom line: if this is all true: you need an immigration attorney. Not only are you possibly endangering your kid --and putting him at risk of foster care you are also putting him at risk for deportation. Just because there was no hold does not mean they can not appear in your house or in your job. Also if your criminal case is still going on they might be giving you the opportunity to finish that process and then they will intervene. Regardless, 99% they will appear and you, and you and your son can face removal proceedings. If you do not solve this issue IN the US and you are deported based on the drug charges you can be permanently bar which means that NO, your wife will not be able to bring you back with an I-130.
You should hire a criminal defense attorney & seek consultation from an immigration attorney, especially if you at considering taking a plea. You most likely will be taken to ICE where you will be detained, your green card will be taken away, and you will not be able to re-enter legally via your wife.
