I don’t think Marijuana is likely to land you in the ED in quite the same way but the habitual smokers I’ve met tended to way underestimate how impaired they are by it and I wouldn’t be surprised if a lot of them drive and operate equipment while suffering those effects. Even the framing of Marijuana as a non-addictive substance seems to be a marketing framing.

Yes, that was kind of my point. Either tobacco is uniquely bad or it can be grouped "along with other drugs". It can't be both.
