I'm not one for drug humor because I find it a lower source for the funny than Power Girl's breasts and drugs are stupid, but sometimes a comic book image comes along that doesn't really lend itself to anything else.
This pipe-like device might be a mailer for subscription comics so they don't get damaged when shipping. It might be a mailing tube, but it looks to me more like Doctor Strange is chilling in his Sanctum while conjuring a mystic portal to the Stash Dimension where he stores his party supplies.
I don't know what genius thought mailing precious comic books by tightly rolling them up was a good idea but it is stupid. It's just as stupid as when they used to mail them flat with just a band of paper around the middle of the book, leaving all the edges to get torn and messed up. Plus, you know all the mailmen were totally reading your Fantastic Four before you did which is wrong on many levels.
