City supervisors recently voted unanimously in favor of banning e-cigarettes; a final vote to confirm the ban will be next week, and it is likely to pass. All e-cigarettes that have not yet been reviewed by the Food and Drug Administration (FDA) would be affected — the FDA has not conducted any assessments yet, meaning all current products would fall under the ban.
Should it pass, the ban would be effective for at least seven months. According to Engadget, the well-known e-cigarette company Juul, which has its headquarters in San Francisco, has thrown its weight behind an effort to block the ban. This effort is collecting signatures to get a measure blocking the ban on the November ballot.
