As to your title, "Ban may be keeping some from entering marine industry." True and not necessarily new although perhaps an increased issue. Some decide pot is more important to them than the industry. That's sure placing pot at a very high importance. We've all dealt with workplace rules we didn't like. I hated wearing a suit and tie to work but did so for several years, early in my career. Have not put a tie on properly since and in the few places one was required I just looped one around my neck without tying it.
Someone mentioned tattoos and piercings. We allow as long as not distasteful or offensive but one of the employers I most respect doesn't allow visible. So, go there and see a girl with her arm wrapped by an ace bandage you know. However, we find acceptance changing as we have little old ladies who shop and are fascinated by the young girl's beautiful tattoos. On the other hand, removal is a thriving business and would be more so if better and not so expensive.
