I’d confront him yourself, without involving your mom or his mom. He’s 16, probably full of piss and vinegar, so confronting him one on one is probably best. Leave the kid a bit of pride.
As a disclaimer, IANAL in Florida and I don’t know their laws. Before you talk to him, you ought to have more information about possible consequences (on preview, this is FinnAgain’s point. Like Wesley Clark said, drug laws are draconian. But a 16 year old won’t believe you if you tell him that growing one small pot of pot (
) in grandma’s garage will put grandma, mom and him in jail and will make grandma lose her house. It just sounds so bizarre.
Based on what I could see, he’s looking at a misdemeanor (1 year in jail and up to $1,000 fine) for cultivating, selling or possessing 20g or less of marijuana (a felony is cultivating, selling or possessing any other amount up to 25 pounds and gets you five years and $10,000 in fines).
Sentences are enhanced for activity near a school, day care, church, etc. Also, conviction for a drug offense means he loses his driver’s license for six months to two years.
So it’s likely if he gets caught, he’s looking at a year in jail and no driver’s license for a while. Those are the official, legal consequences. (Generally, asset forfeiture – where your mom could lose her house – is a consequence of trafficking, which requires significantly more pot than your nephew is growing.)
So I would actually focus less on the jail-type consequences of his actions, and more on the things that are important to you: how those actions affect your mom. First, if he’s caught, they’ll search the whole house for drug paraphernalia, going through all your mom’s things. That’s pretty stressful.
Next, he’ll need a lawyer (he can just plead guilty, but you likely love him and want to give him the best opportunity to minimize the impact). The cost will likely be between $5,000 and $20,000. More, if the prosecution fights. Who will pay? Your mom has an asset – the house – that she could put up to get a loan to pay the lawyer.
Is your mom on any kind of public assistance? Some programs say that if the recipient is involved in drugs in some way, she loses benefits. Or if she has a mortgage, there could be a clause in her loan that forbids the property from being used in an illegal way.
Finally, your nephew will have a hard time paying for college; some types of financial aid are simply unavailable to convicted druggies. And if he gets a felony instead of a misdemeanor, he could find himself struggling to find a job.
Bottom line: when the only person he is putting at risk with his behavior is himself, then he can just go for it. But until he is out on his own, he needs to be respectful of the precarious position that his actions can put people in.
