My question involves criminal law for the state of: Ohio
I'm a 19 year old living at my parents house casually for and. they found less than an 8th of weed and a small pipe in my room. I have 3 little sisters, 1 starting high school and 2 young elementary schoolers.
My mother then told me I had a week to pack my things and get out of the house, which I got cut down to an hour. I was let back in the house half a day later and I of course had talks with both separately.
Before this when I was still in the process of leaving I was warned to leave before my mother decided to call the cops. She told me simply for possibly having marijuana in my system from 2 days ago they would arrest me after a test.
A day later when we had our talk she explained her terror to me that social services would come and take my little sisters away, then the police would take their car away(that had nothing to do with this as its rarely used by me and was never smoked in nor had anything hidden in it) and never give it back, I guess as evidence, and finally arrest not only me but my parents as well.
Simple question is if any of this is true? While I'm not sure how my sisters' presence in the house would have effected the charges, I have never heard of such extreme action taken for such minor possession. Especially when the evidence had already been destroyed and this is a first time I've could have been in trouble for such a thing. I live in Oberlin Ohio if that effects anything.
My mom also believes simply being pulled over with a small amount of marijuana, intoxicated or not, would get whatever car I'm in taken away indefinitely.
