if you base it on Genre ng music it's not nice to see them doing this
WHY?hmmmmm...... le me think about it....idk
maybe because
most of their fans are 18 Years old younger and they are a pop band who's exposed to different kinds of people including Parents and Children who sings their songs during long drive on their car
not saying it's cool for a rock star to roll a joint or a rapper to smoke a joint
i live in California so it's normal for me to see old guys rolling or using it while walking specially African American People
