none. an opiate
A narcotic is an Opiate or an Opioid such as Heroin, Vicodin, Dilaudid ect.
Marijuana, or rather tetrahydrocannabinol (THC) is a mild hallucinogen. Both opiates and designer drugs can be hallucinogens, however, an opiate is a drug that's derrived from the opium plant and cannot be a designer drug (100% artificially designed for a certain purpose).
Codeine is a depressant opiate. It depresses the Central Nervous System (CNS). Codeine is a pro-drug. It converts to morphine in the body.
Ketamine, also known as special k, is a dissociative anesthetic, a type of hallucinogen.
It will have to be LSD. Or possibly alcohol?
PCP. Also known as Angel Dust; quite possibly the most dangerous hallucinogen
Methadone would fall under depressants.
Opium can cause extreme sedation that may produce a state of drifting in and out of consciousness. With this comes fleeting dreams, confusion, and other effects that produce something akin to a hallucination. Opium is not, however, a hallucinogen in the technical sense; it is an opiate. Opiates belong to a class of drugs known as central nervous system depressants. Other examples of opiates are codeine and morphine, and there are also semi synthetic opiates such as heroin and oxycodone and fully synthetic opiates such as methadone and buprenorphine.
