Vapes, also known as e-cigarettes, typically contain a liquid that is heated to produce an aerosol, which is then inhaled. This liquid, often referred to as e-juice or vape juice, is a mixture of ingredients, most commonly including nicotine, flavorings, and other chemicals. 

Here’s a more detailed look at the components of vape content:

1. Nicotine: This is the addictive substance found in tobacco products and is a primary ingredient in many vape liquids. Nicotine levels can vary significantly between different brands and strengths. 

2. Flavorings: Vapes come in a wide variety of flavors, ranging from fruity to sweet and even savory. Each flavoring has its own unique set of ingredients, which can include artificial sweeteners, food coloring, and other additives. 

3. Propylene Glycol (PG) and Vegetable Glycerin (VG): These are the main solvent carriers in vape liquids. PG and VG are used to create the vapor that users inhale. PG is generally considered safer than VG when inhaled. 

4. Other Chemicals: Vape liquids may also contain other chemicals in varying amounts, including:

• Aldehydes: These are volatile organic compounds that can be harmful when inhaled. 
• Heavy metals: Some studies have found trace amounts of heavy metals, such as lead, nickel, and arsenic, in vape aerosols. 
• Other compounds: Aerosol can contain various other chemicals, such as acetone, acrolein, and 2-chloropheno
