The rally, organized by the Free Hemp Initiative, was attended by up to 6,000 demonstrators — and that’s a police estimate, so the crowd could have been even larger.

“Forty people were detained during the march, including six minors,” said Deputy Inspector Maciej Karczynski of the Warsaw Police, reports TheNews.pl. Karczynski added that 28 of those detained were arrested for possession of cannabis, while one person was detained for shoplifting.
