Should a person tell any prospective employer that they used weed a few times earlier on in their life?

Hi all! I'm doing a survey about occasional drug use, particularly marijuana. Should a person tell any prospective employer that they used weed a few times earlier on in their life? For instance, if some wants to apply for a police position, whether it's at the federal, state, county level, etc., would that even be a case where the person should tell any prospective employer that they used weed a few times earlier on in their life for experimental, curiousity, and recreational purposes? Would mentioning it really affect the person getting employed or not? Afterall, they're just being honest and they haven't used it at all since then. I don't believe in lying even though many people lie each and everyday all around the world. In terms of employment and careers, would that be a case not to mention it even it would be "lying"? Any answers would be appreciated. Thanks!
