A drug is any substance that changes bodily functions. A gateway drug is a drug that is though to lead to the use of more dangerous drugs. Examples of gateway drugs are caffeine, tobacco, and alcohol. These are readily available, but sold to only adults. Whichever reasons people have in using these substances, you need to know the facts plus develop the right behavior and attitude toward it so that you will prevent and control yourself from abusing it.

Hope it helps! Give love, and love well
