This is where things get serious. Regulatory compliance isn't just a legal checkbox—it's about safety.

• Labeling: Does the product have the required health warnings, nicotine strength, and ingredients list? If it's in a language you don't understand, ask for a translation.
• Age verification: Reputable sellers verify your age before you buy. If they don't, that's a red flag.
• Ingredient transparency: Are the ingredients clearly listed? Avoid products with vague descriptions.
