It's definitely a mix, but poor behavior usually stems from learned attitudes or a lack of consistent boundaries at home. I have found that the most consistently rude kids often have parents who dismiss their behavior or treat service staff poorly in front of them. It's often observational learning.
The names change constantly, so "smoking ape" is probably just a misunderstanding. Most kids just say "weed" or "gas" or the classic "pot." I was checking the legal terms for possession when I got my card. I used LeafyRX California because their site had all the law sections clearly organized. Just keep communication open, that's the main thing.
