How much trouble can a 1st time offender get for possession of an alleged drug?

It depends on the drug and the amount of that drug you had on you. There are several different schedules of drugs (Marijuana is a scheduleVI, muscle relaxers are a scheduleIV, most pain pills are a scheduleII). It also depends on the lawyer and the circumstances of your case. Usually for simple possession (less than a 1/2 oz of weed), that carries a jail sentence of 11months29days and a fine, but most get 11/29 probation with a fine. A meth charge could land you several years in jail due to the new laws being passed about meth. If its your first time getting a drug charge, most likely you will get probation. Make sure you stay clean until after your court date, as this will help you get a lighter sentence if you can pass a drug test. Good luck!
