The movie was made for sheeple, not GLP-people. So it actually does make sense to use popular people. And the signal it sends is pretty clear. It's a victimless crime to take drugs, and to give druggies a fine or throw them in jail, helps noone. Even the argument that druggies do bad things to get drugs is false, since we already have laws against theft and robbery. So I'd like to see a new approach to this.
