The ideal dosage of caffeine for vaping is not well established and can vary depending on a number of factors, including an individual's age, weight, tolerance, and sensitivity to caffeine. In general, it's recommended to start with a low dosage and increase gradually until the desired effect is achieved.
According to the Centers for Disease Control and Prevention (CDC), a safe and moderate amount of caffeine for most healthy adults is up to 400 milligrams per day, which is roughly equivalent to four cups of brewed coffee. However, the CDC notes that some people are more sensitive to caffeine and may experience negative side effects at lower doses.
It's important to keep in mind that the amount of caffeine in e-liquid used for vaping can vary greatly, and some products may contain significantly more caffeine than others. It's always best to check the label or ask the manufacturer for information on the amount of caffeine in a specific product. Additionally, it's important to be cautious and start with a low dose, especially if you have never used caffeine vapes before.
It's also worth noting that caffeine can cause negative side effects, such as rapid heartbeat, increased anxiety, or insomnia, even at moderate doses. If you experience any of these symptoms, it's best to stop using caffeine vapes and consult a doctor.
