Answer:
False.
Step-by-step explanation:
A drug is a substance which a person takes into their body and it changes their body's function, physical or mental. Some of drugs are legal -- caffeine, alcohol and tobacco, while cannabis, ecstasy, cocaine and heroin are illegal.
There is no safe way to measure drugs in order to avoid overdosing, as every kind of drug can be lethal, even if used in small amounts. Anyone can be at risk, but people between 12-29 years are most likely to abuse drugs.
Using drugs leads to drug tolerance. It's when a person needs more and more drugs in order to feel the effect of it. Drug tolerance leads to drug dependence, a state in which a person feels like their world revolves around drugs and they go through withdrawal symptoms if they stop using it.
