THC, including delta-9 THC, can have side effects. A Delta-9 high is characterized by strong psychoactive effects. Users may experience visual and auditory hallucinations, motor skill disorders, and paranoia. The euphoric effect of delta-THC usually lasts for two to four hours.
This supports a complex interaction between CBD and THC, whose effects are not offset by CBD under all circumstances. It is quite possible that previous treatment with CBD is more effective in other cognitive areas than those applied in the present study, since it has been suggested that CBD, in particular, protects memory performance dependent on the hippocampus from the impact of THC (20). THC is the cannabinoid responsible for people experiencing an intoxicating effect when they consume cannabis. The only difference between Delta 8 and Delta 9 THC is that the double bond in which a specific carbon atom in the chain has two bonds is placed in different places in the chain.
Some people may argue that there are no major distinctions between Delta 8 and Delta 9, but the subtle chemical distinction can cause cognitive changes and physiological effects. In particular, the latter is essential, since CBD has recently been approved as an orphan drug for Dravet and Lennox-Gastault syndrome in children and its beneficial effects on other diseases are currently being investigated. In fact, the WHO has proposed to reprogram Delta (-THC) in list IV of the United Nations Convention on Psychotropic Drugs, since it does not pose a substantial risk to public health and its abuse is rare, if at all. Cognitive and subjective effects of acute oral delta 9-tetrahydrocannabinol (THC) dose response in infrequent cannabis users.
In its chemical structure, Delta 8 has an eighth carbon atom with a double bond; Delta 9 contains a ninth carbon atom with a double bond. As there is some evidence that CBD may be effective in other cognitive domains other than those investigated in the present study, more studies are needed to clarify the intricate interrelationship between phytocannabinoids and cognition. This is the same as delta-8, except that one of the carbon-carbon double bonds is in a different position. Side effects are more severe with Delta 9 and include paranoid delusions, mental confusion, motor impairment, and anxiety.
Once in the brain, Delta 9 binds to CB-1 receptors and can produce strong psychoactive effects, such as feeling euphoric or relaxed, talking and laughing uncontrollably.
