Verified step by step guidance

1. Understand the context of the question: Barbiturates are a class of drugs that act as central nervous system depressants.
2. Identify the characteristics of barbiturates: They are used to induce sedation and sleep, and in higher doses, they can act as anesthetics.
3. Differentiate between major and minor tranquilizers: Major tranquilizers, also known as antipsychotics, are used to treat severe mental health disorders, while minor tranquilizers, such as benzodiazepines, are used for anxiety and insomnia.
4. Consider the term 'gateway drugs': These are substances that may lead to the use of more dangerous drugs, often associated with substances like tobacco or alcohol.
5. Evaluate the term 'hallucinogens': These are drugs that cause perceptual anomalies and hallucinations, such as LSD or psilocybin, which do not align with the effects of barbiturates.
