Depending on the weight of the drugs and whether the crime occurred in a school zone, there is possibly a mandatory jail sentence in the event of a conviction. There are so many issues involved so you need to retain an experienced criminal defense attorney. The sooner you hire a lawyer the better.
I assume when you state that you, "now have a felony . . ." you simply mean you have been charged with a felony drug offense. The direct answer to your question is YES, you could go to jail or prison depending on a number of factors only one of which is within your control. The type of controlled substance and the amount. Pennsylvania's Drug Act has several provisions creating mandatory minimum periods of incarceration for felony drug convictions. Your prior criminal history will impact the likelihood of incarceration, especially any prior felony drug convictions. The strength of the case against you and whether you made any admissions to police at the time of your arrest will bear upon the likelihood of a conviction. Before jail or prison becomes possible, the Commonwealth has to get a conviction. Accordingly, your first order of business should be engaging the services of an experienced criminal defense attorney skilled in the handling of drug cases. I suggest you not post any more details on the Internet and concentrate on securing a good attorney. Good luck.
You certainly could go to jail. The likelihood depends upon whether you are convicted of simple possession or intent to deliver. If it is intent to deliver, the weight is very important. I do not view this as definite jail time, even if convicted of intent to deliver, unless this is an extreme amount. Many things will factor into this. Contact an attorney to discuss this further.
