Google also allows ads targeting a list of emails. Could be that the cigar seller asked google to show you the ads.

  Why would the cigar seller ask to show me an ad for a STOP SMOKING CIGARS product? Also as I said, this showed up in Youtube the day after I ordered and the email hit my gmail. Never seen those ads before.

    The cigar seller sells its customer list to a data broker or uses a third party service that does the same (e.g. it uses your email address as a user identifier in a third party analytics product). Then advertisers buy that data.

        Well, it's not like they need to ship the list of email addresses across the company in a truck.
