it is a federal crime to lie on that form

But are you really lying when you think or feel you're answering truthfully?

I.e., what is regular? Once a month? Once a week? These seem more "occasional" than "regular". And even at 3+ times per week, in "regular" territory, what if you stop?

Are you still a regular smoker if you've been clean for a month? Two months? Three or four? Six or a year?

Of course, this is all under the assumption they don't just get ICE'd or Venezuela-boated.
