Users often report: - seeing colors as being more vibrant, - shapes appearing distorted, - patterns moving as if they were “breathing.” Some users have also reported feeling as though their sense of depth has been altered, which causes them difficulty judging distance. Many users also report that time appears to be distorting, which makes minutes feel like hours. While technically, this is not a hallucination, but a change in the way the user perceives their senses and time, it can be unsettling for some users. ## Sensory Processing Changes in the Brain Due to High Doses of THC When a person consumes large quantities of THC, they may experience changes in how the brain processes sensory input, which may feel like hallucinations to the individual. ## Risk Factors That Increase the Probability of Having a Strong Psychological Response to Cannabis There are several factors that increase the probability of having a strong psychological response to cannabis: - Using high-THC cannabis products (more than 20% THC) - Taking high doses of edible cannabis products (delayed onset and increased risk of over-dosing) - Having low tolerance to cannabis or being new to using cannabis - Combining cannabis with alcohol or other drugs/substances - Experiencing stress and/or anxiety in an unfamiliar environment - Using concentrates (such as dabs and hash oil) due to rapid onset and high potency Modern cannabis products contain levels of THC that exceed 30%, and thus are more potent than past products. Edible cannabis products pose a particular risk because the effects may take up to two hours to develop. Inexperienced users may ingest additional edible cannabis before waiting long enough for the initial dose to take effect, and subsequently experience extremely intense reactions for six to twelve hours. ### Comparison of the Risks Associated with Different Methods of Consuming Cannabis Products | **Method** | **Onset Time** | **Duration** | **Risk of Hallucinations** | | --- | --- | --- | --- | | Smoking/Vaporizing | Immediate/2–5 min | 1–3 hr | Moderate | | Vaping | Immediate | 1–3 hr | Moderate | | [Edibles](/product-category/edibles/) | 30–120 min | 6–12 hr | Higher | | Concentrates (Dabs/Hash Oil) | Immediate | 2–5 hr | High | Smoking and vaporizing allow users to rapidly adjust their cannabis consumption. Concentrates are absorbed into the bloodstream at a rapid rate, and experienced users may be overwhelmed by the speed of absorption. ## Length of Cannabis-Related Hallucination-Like Experiences The length of cannabis-related hallucination-like experiences vary greatly among users, and typically include: - **Smoking/vaporizing:**1–3 hours - **Strong edible cannabis products:**Up to 12 hours Typically, all cannabis-related hallucination-like effects will fade completely within 24 hours. However, some users report residual mental fogginess and/or mild visual sensitivity immediately after experiencing particularly intense reactions. ## Explore Cannabis Safely and Responsibly To avoid unwanted side effects, we recommend starting with very small amounts of cannabis, and then gradually increasing the amount until you understand how cannabis affects you personally.
