Effects of cannabis - Psychology Wiki. Assessment . Cannabis has both psychological and physiological effects on the human body.
Five European countries, Canada, and nineteen US states (as of 7/8/1. Some varieties, having undergone careful selection and growing techniques, can yield as much as 2. THC. How these other compounds interact with THC is not fully understood.
Some clinical studies have proposed that CBD acts as a balancing force to regulate the strength of the psychoactive agent THC. Marijuana with relatively high ratios of CBD: THC is less likely to induce anxiety than marijuana with low CBD: THC ratios. Experiments in which mice were treated with CBD followed by THC showed that CBD treatment was associated with a substantial increase in brain concentrations of THC and its major metabolites, most likely because it decreased the rate of clearance of THC from the body. The essential oil of cannabis contains many fragrant terpenoids which may synergize with the cannabinoids to produce their unique effects. THC is converted rapidly to 1.

THC, which is also pharmacologically active, so the drug effect outlasts measurable THC levels in blood. Research in rats has indicated that THC prevented hydroperoxide- induced oxidative damage as well as or better than other antioxidants in a chemical (Fenton reaction) system and neuronal cultures. Cannabidiol was significantly more protective than either vitamin E or vitamin C.
Cannabinoids usually contain a 1,1'- di- methyl- pyrane ring, a variedly derivatized aromatic ring and a variedly unsaturatedcyclohexyl ring and their immediate chemical precursors, constituting a family of about 6. Like most other neurological processes, the effects of cannabis on the brain follow the standard protocol of signal transduction, the electrochemical system of sending signals through neurons for a biological response. It is now understood that cannabinoid receptors appear in similar forms in most vertebrates and invertebrates and have a long evolutionary history of 5. Cannabinoid receptors decrease adenylyl cyclase activity, inhibit calcium N channels, and disinhibit K+A channels. There are two types of cannabinoid receptors (CB1 and CB2). The CB2 receptor is most abundantly found on cells of the immune system.
Cannabinoids act as immunomodulators at CB2 receptors, meaning they increase some immune responses and decrease others. For example, nonpsychotropic cannabinoids can be used as a very effective anti- inflammatory. Cannabinoids likely have a role in the brain’s control of movement and memory, as well as natural pain modulation. It is clear that cannabinoids can affect pain transmission and, specifically, that cannabinoids interact with the brain's endogenous opioid system and may affect dopamine transmission. A signature of this type of receptor is the distinct pattern of how the receptor molecule spans the cell membrane seven times. The location of cannabinoid receptors exists on the cell membrane, and both outside (extracellularly) and inside (intracellularly) the cell membrane. CB1 receptors, the bigger of the two, are extraordinarily abundant in the brain: 1.

CB2 receptors are structurally different (the sequence similarity between the two subtypes of receptors is 4. CB1 counterpart. CB2 receptors are most commonly prevalent on B- cells, natural killer cells, and monocytes, but can also be found on polymorphonuclear neutrophil cells, T8 cells, and T4 cells.
In the tonsils the CB2 receptors appear to be restricted to B- lymphocyte- enriched areas. The THC molecule, and related compounds, are usually detectable in drug tests from 3 days up to 1. Redwood Laboratories, heavy users can produce positive tests for up to 3 months after ceasing cannabis use (see drug test). In lab animal tests, scientists have had much difficulty administering a dosage of THC that is high enough to be lethal. Indeed, a 1. 98. 8 ruling from the United States Department of Justice concluded that . According to a 2. United Kingdom government report, using cannabis is much less dangerous than tobacco, prescription drugs, and alcohol in social harms, physical harm, and addiction.
The subjective experience induced by imbibing in cannabis use can be considered stimulatory and yet also sedative or depressant, while also having markedly mild psychedelic and even dissociative characteristics. Anxiety is the most commonly reported side effect of smoking marijuana.
At higher doses, effects can include altered body image, auditory and/or visual illusions, pseudo- hallucinatory or (rarely, at very high doses) fully hallucinatory experiences, and ataxia from selective impairment of polysynaptic reflexes. In some cases, cannabis can lead to dissociative states such as depersonalization. Effects can typically last two to three hours. On three separate days, subjects smoked one NIDA marijuana cigarette containing either 0%, 1.
THC, documenting subjective, physiologic, and performance measures prior to smoking, five times following smoking on that day, and three times on the following morning. Subjects reported robust subjective effects following both active doses of marijuana, which returned to baseline levels within 3. Heart rate increased and the pupillary light reflex decreased following active dose administration with return to baseline on that day.
Additionally, marijuana smoking acutely produced decrements in smooth pursuit eye tracking. Although robust acute effects of marijuana were found on subjective and physiological measures, no effects were evident the day following administration, indicating that the residual effects of smoking a single marijuana cigarette are minimal. This is reflected by an increase of the occurrence of impaired psychomotor skills, particularly among younger or inexperienced cannabis smokers, who do not always adapt their smoking- style to the higher THC content.
It was also observed during the study that the effects from a single joint lasted for more than eight hours. Reaction times remained impaired five hours after smoking, when the THC serum concentrations were significantly reduced, but still present.
However, it is important to note that the subjects (without knowing the potency) were told to finish their (unshared) joints rather than titrate their doses, leading in many cases to significantly higher doses than they would normally take. Also, when subjects smoke on several occasions per day, accumulation of THC in blood- serum may occur. Also, oral use eliminates the need to inhale toxic combustion products created by smoking, which eliminates much of the respiratory and cardiovascular harm associated with cannabis smoking.
Brain regions in which cannabinoid receptors are very abundant are the basal ganglia, associated with movement control; the cerebellum, associated with body movement coordination; the hippocampus, associated with learning, memory, and stress control; the cerebral cortex, associated with higher cognitive functions; and the nucleus accumbens, regarded as the reward center of the brain. Other regions where cannabinoid receptors are moderately concentrated are the hypothalamus, which regulates homeostatic functions; the amygdala, associated with emotional responses and fears; the spinal cord, associated with peripheral sensations like pain; the brain stem, associated with sleep, arousal, and motor control; and the nucleus of the solitary tract, associated with visceral sensations like nausea and vomiting. Cannabinoids, depending on the dose, inhibit the transmission of neural signals through the basal ganglia and cerebellum. At lower doses, cannabinoids seem to stimulate locomotion while greater doses inhibit it, most commonly manifested by lack of steadiness (body sway and hand steadiness) in motor tasks that require a lot of attention.
Other brain regions, like the cortex, the cerebellum, and the neural pathway from cortex to striatum, are also involved in the control of movement and contain abundant cannabinoid receptors, indicating their possible involvement as well. Cannabinoids inhibit the release of several neurotransmitters in the hippocampus, like acetylcholine, norepinephrine, and glutamate, resulting in a major decrease in neuronal activity in that region.
This decrease in activity resembles a . Compared to currently approved drugs prescribed for the treatment of Alzheimer's disease, THC is a considerably superior inhibitor of A aggregation, and this study provides a previously unrecognized molecular mechanism through which cannabinoid molecules may directly impact the progression of this debilitating disease.
The report summarizes current knowledge about the effects of cannabis on driving and accident risk based on a review of available literature published since 1. This is due to driving inexperience and factors associated with youth relating to risk taking, delinquency and motivation. These demographic and psychosocial variables may relate to both drug use and accident risk, thereby presenting an artificial relationship between use of drugs and accident involvement.
Both simulation and road trials generally find that driving behavior shortly after consumption of larger doses of cannabis results in. The researchers note that . There were about 5. Europe. In Europe, cannabis is typically mixed with tobacco, in contrast to North America.
A similar increase in heart disease and ischemic strokes is observed in tobacco smokers, which suggests that the harmful effects come from combustion products, not marijuana. Some critics question whether agencies doing the research make an honest effort to present an accurate, unbiased summary of the evidence, or whether they . The study concluded, . Evidence from a controlled experimental study undertaken by Lukas and Orozco. Data from the Australian National Survey of Mental Health and Wellbeing. Clinical studies and survey data have found that cannabis increases food enjoyment and interest in food.
