Yes, weed, also known as marijuana or cannabis, can cause hallucinations, especially when consumed in large quantities or at high levels of potency. The hallucinogenic effects of marijuana are generally less pronounced compared to drugs like LSD or psilocybin mushrooms, but they can still occur, particularly in higher doses or in individuals who are more sensitive to its effects.
The main psychoactive compound in marijuana is delta-9-tetrahydrocannabinol (THC), which can alter sensory perceptions and lead to hallucinations in some users. These hallucinations can manifest as distortions in the perception of colors, shapes, and sizes, which may be why your friends appeared 2D when you were high.
The response to marijuana varies widely from person to person and can be influenced by factors such as the individual's tolerance, the potency of the strain consumed, the method of consumption, and the setting in which the drug is taken. Additionally, marijuana can interact with other substances or medications, potentially intensifying its effects.
It's important to be cautious when using marijuana, especially if you are unfamiliar with its potency or if you are consuming it for the first time. Overconsumption of marijuana can lead to adverse effects, including anxiety, paranoia, and hallucinations, as you experienced.
If you decide to use marijuana in the future, it's essential to do so responsibly and in a safe environment. If you have concerns about your experiences with marijuana or if you continue to have distressing hallucinations, it's best to consult with a healthcare professional who can provide guidance and support. Remember that everyone's response to marijuana is different, and what may be a normal experience for one person might be overwhelming or uncomfortable for another.
