E-cigarettes, vapes, vape pens, personal vaporizers, nicotine vaporizers, mods, and Advanced Personal Vaporizers (APV) are virtually the same thing: battery powered devices that provide an inhaled dosage of nicotine, marijuana, or other drugs- though most typically used for nicotine.
For simplicity, GCSAPP will refer to these devices as vaporizers, as they heat oils from substances such as tobacco or marijuana into a vapor.
Food and Drug Administration (FDA) regulations make vaporizers illegal for people under the age of 18 to possess. Additionally, it is illegal sell and distribute vaporizers to minors. Locally, the Gunnison City Council updated its tobacco ordinance in 2017 to include language clarifying vaporizers as tobacco products. A link to the ordinance can be found here.
According to a report by the Surgeon General, Dr. Vivek H. Murthy, e-cigarette use among high school students increased "an astounding 900 percent" from 2011 to 2015. Some researchers have said that e-cigarette use among youth could act as a gateway to traditional smoking, but the report says the relationship is not yet fully established. Chief among the concerns raised by the report is simply that "nicotine is a dangerous drug" to the developing brain (see more below).
