re: Anyone here use a smoke gun for smoking cocktails, cheese etc?

Bumping this because I have a client who is big time foodie and we were talking about smoke guns. She says sometime she cooks a pork butt in a slow cooker and then used a smoke gun to impart a smoky flavor. Says it tastes like it had been on a smoker for hours. I’m a little skeptical but think I’m going to give a try today. Anyone here tried this before?
