A 'gateway drug' is a drug that is believed to increase the likelihood of a person using more harmful drugs in the future. Typically, these are commonly accessible substances like alcohol, tobacco, or marijuana. The theory suggests that using these substances can normalize drug use and potentially lead to experimentation with more dangerous drugs. However, this concept is debated, and the relationship between 'gateway drugs' and harder drugs is complex and not always causal. Think of it as a potential starting point on a dangerous path. 'Gateway drug' is like the on-ramp to a risky highway.
