Drinking alcohol can interfere with your ability to concentrate, induce a deep sleep (from which it’s hard to waken) and cause distraction. It also inhibits your ability to react effectively. Many drugs also have the same effect and, when taken at the same time as alcohol, can exacerbate the impact. Our advice, therefore, is that you should not cook, smoke cigarettes, or use candles when under the influence as you are more likely to cause an accident and increase the risk of fire e.g. by knocking a candle over, forgetting you’ve got something cooking on your hob, dropping or not extinguishing your cigarette properly and falling asleep.
