"I have no previous criminal record, do you think via a plea bargain or a diversion program I would be able to avoid jail?"
*** Sorry, but no body can answer this question with any authority, since it is mainly based on far too many unknowns (the strength of the case against you, the 'aggressiveness' of the DA's office, what you might have to offer in 'trade', etc.).
However, I can provide the statute and what the STATUTORY penalty can be:
"§ 2925.03 Trafficking in drugs. -
(3) If the drug involved in the violation is marihuana or a compound, mixture, preparation, or substance containing marihuana other than hashish, whoever violates division (A) of this section is guilty of trafficking in marihuana. The penalty for the offense shall be determined as follows:
<snip>
(c) Except as otherwise provided in this division, if the amount of the drug involved equals or exceeds two hundred grams but is less than one thousand grams, trafficking in marihuana is a felony of the fourth degree, and division (C) of section 2929.13 of the Revised Code applies in determining whether to impose a prison term on the offender. If the amount of the drug involved is within that range and if the offense was committed in the vicinity of a school or in the vicinity of a juvenile, trafficking in marihuana is a felony of the third degree, and division (C) of section 2929.13 of the Revised Code applies in determining whether to impose a prison term on the offender.
(d) Except as otherwise provided in this division, if the amount of the drug involved equals or exceeds one thousand grams but is less than five thousand grams, trafficking in marihuana is a felony of the third degree, and division (C) of section 2929.13 of the Revised Code applies in determining whether to impose a prison term on the offender. If the amount of the drug involved is within that range and if the offense was committed in the vicinity of a school or in the vicinity of a juvenile, trafficking in marihuana is a felony of the second degree, and there is a presumption that a prison term shall be imposed for the offense."
From the above, the 1000 grams puts this as a third degree felony.
Punishment can be one to five years in prison.
