Emailed my son in Amsterdam, since in May (when we visited him) this was not the case. He replied, "started 1 July. Funnily enough, inside coffee shops, smoking grass or hash is still OK, but one cannot mix tobacco in the joints, as is normally done. Substitutes have been tried."

And a cleaned up Red Light District! I suppose Thailand is next! LOL
