This is reportedly video of Aldon Smith's hand holding a blunt that the suspended 49er posted on Periscope.  According to CSN Bay Area the account that posted the video belongs to Smith, although in this particular video you do not see his face.

Some older videos are archived, and Smith has used an account titled “ravenga,” to post video segments under the name “Ricky.”

The account, as of Sunday morning, has 29 followers. Smith is clearly shown on camera in most videos, where he generally talks about current events or what he’s doing at the moment.

Not the sharpest tool in the shed.  Just another dumbass doing some dumbass shit and acting like he's intouchable.  Dude you've already been suspended for a year.  I think you should listen to the chick in the video.
