So, how do you apply this when you're shopping? Here's a practical checklist:

1. Read the warning label—if it doesn't have the nicotine warning, put it back.
2. Check for child-resistant features—try to open it if you can; it should be tough for a kid.
3. Look for nicotine content—make sure it matches what you expect.
4. See if there's a Prop 65 warning—if not, it might not be compliant.
5. Buy from licensed stores—they're more likely to stock compliant products.

For example, a product like the VERTEX-25K should have a clear nicotine warning and child-resistant packaging. If you see that, you're off to a good start.
