Energy drinks are often mixed with alcohol. Where energy drinks are stimulants, alcohol is a depressant. The mix can be particularly hazardous as energy drinks can mask the influence of alcohol and a person can fail to take its effects into consideration.[21] Normally fatigue would set in as large amounts of alcohol are being consumed, but the stimulating effect of energy drinks can override this effect.[22] Often drunk with vodka or in shots it has lead to increase in the purchase of pre-mixed drinks also known as alco-pops often containing guarana or taurine extract which provides energy drinks with their flavour.
