Not really a surprise. The US has essentially admitted that not only users of marijuana face denial of entry and a possible lifetime ban, but also anyone who works in the industry or even invests in the industry also faces the same. This confirms anecdotal evidence that this is already occurring.
The US still views marijuana as illegal and therefore a criminal activity and profiting from an illegal activity is how the ban is being framed/justified.
