IF - "if" - it is his first offense, he will probably fall back on the First Offender Amendment and get probation. That is 99% chance of happening.
I know two people who were busted for drugs. One guy had 7 amps of sust. The other guy had 300 (10 bottles) of Pfizer Viagra, 2x500 count bottles of Lortabs, 1000 (bulk bottle) of Valium 10mg and 200 Xanax tabs.
Here in Florida they both got the same sentence. $1500 fine. 200 hours community service. 5 years probation. 1 year of 2x weekly narcotics anonymous meetings - because the first guy had sust which is injectible and required needles, he had to attend 6 months detox counseling 3x a week in the afternoons. Same as a herion addict. (spent the other 2 days doing the NA).
I don't think the guy is going to get jail time.
