Once you've bought a product, keep an eye on it. After using it for a week, ask yourself:

• Does the packaging still look intact? Any damage could affect child-resistance.
• Did the product perform as expected? If not, it might be a quality issue.
• Check for any recalls or safety notices from the manufacturer or state.

Staying alert after purchase helps you spot problems early. If something seems off, report it to the California Department of Public Health.
