Hawaii has become the first state to raise the legal tobacco use age to 21.
The law prohibits people under the age of 21 from smoking, buying, or possessing tobacco products.
The law specifically includes electronic smoking devices, defined as "any electronic product that can be used to aerosolize and deliver nicotine or other substances to the person inhaling the device, an electronic cigarette, electronic cigar, electronic cigarillo, or electronic pipe, and any cartridge or other component of the device or related product."
