Morphine is a drug which is cultivated from the opium poppy, and is actually the principal constituent of opium and is used to produce other opiate drugs as well.
The visual distortions produced by LSD are often referred to as "pseudo-hallucinations" because people are aware that what they are seeing is not real due to the effects of the drug.
Studies suggest that as little as a single dose of morphine could contribute to addiction.
Magic mushroom use can result in nervousness and paranoia.
