This *might* be a reference to Smokescreen’s, uh, habit. What he’s actually smoking is a broken LEGO piece (yes, after thirty years, I’ve accumulated a stash of broken ones too and I just won’t throw them away – you never know when one might be useful).
As far as the possible drug reference, all I can say is behave yourselves, kids. This will be dealt with in the strip. 🙂
