“…For example, Gilman et al (12) found that increased risk-taking behavior in CB users depended on stimulus type with greater risk-taking observed when the rewards were social, health/safety, and ethical factors but not when the rewards were monetary. A study by Vivas et al (11) found that CB use actually enhanced inhibitory control compared to non-users. Another study used transcranial direct current stimulation (tDCS) to stimulate the left and right dorsal lateral prefrontal cortex (DLPFC) in chronic cannabis users and controls and found that chronic cannabis users made more conservative decisions than controls during sham stimulation (placebo) but during active stimulation of the right DLPFC, controls made more conservative decisions while activations of both right and left DLPFC in cannabis users led to increased risk-taking (13).…”

“…While the chronic use of alcohol and other drugs of addiction have been associated with increased risk-taking behaviors and poor inhibitory control (9), CB use has not consistently been found to be linked to increased risk-taking (10,11). For example, Gilman et al (12) found that increased risk-taking behavior in CB users depended on stimulus type with greater risk-taking observed when the rewards were social, health/safety, and ethical factors but not when the rewards were monetary.…”

Does Chronic Cannabis Use Impact Risky Decision-Making: An Examination of fMRI Activation and Effective Connectivity?

With the increase in use of cannabis and its shifting legal status in the United States, cannabis use has become an important research focus. While studies of other drug populations have shown marked increases in risky decision-making, the literature on cannabis users is not as clear. The current study examined the performance of 17 cannabis users and 14 non-users on the Balloon Analog Risk Task (BART) using behavioral, fMRI and effective connectivity methods. Significant attenuation was found in a functional pathway projecting from the dorsal anterior cingulate cortex (dACC) to the nucleus accumbens (NAc) in cannabis users compared to non-using controls as well as decreases in risk-taking behaviors. These findings suggest that cannabis users may process and evaluate risks and rewards differently than non-users.

“…These results suggest that the IOR of poker players is enhanced compared to that of controls. This type of result has already been observed in a population of cannabis users (Vivas, Estevez, Moreno, Panagis, & Flores, 2012) (see (Colzato & Hommel, 2009) for opposite results) and cocaine users after taking a dose of dextroamphetamine (Fillmore, Rush, & Abroms, 2005). The enhanced IOR found in these populations suggests that the IOR can be improved by the ingestion of drugs, such as cannabis.…”

“…The enhanced IOR found in these populations suggests that the IOR can be improved by the ingestion of drugs, such as cannabis. Nevertheless, the mechanisms are still not understood ( Vivas et al., 2012 ). Other studies, gathered in a systematic review, have assessed the effect of alcohol, ecstasy, and hallucinogens.…”

Background and aimsThis research aimed to characterize social information processing abilities in a population of regular nondisordered poker players compared to controls.MethodsParticipants completed the Posner cueing paradigm task including social cues (faces) to assess attention allocation towards social stimuli, including the effect of the presentation time (subliminal vs supraliminal) and of the emotion displayed. The study included two groups of participants: 30 regular nondisordered poker players (those who played at least three times a week in Texas Hold'em poker games for at least three months) and 30 control participants (those who did not gamble or gambled less than once a month, whatever the game).ResultsThe group of regular nondisordered poker players displayed an enhancement of the inhibition of return during the Posner cueing task. This means that in valid trials, they took longer to respond to the already processed localization in supraliminal conditions compared to controls. However, our results did not evidence any particular engagement or disengagement attention abilities toward specific types of emotion.Discussion and ConclusionsThese results suggest that regular nondisordered poker players displayed social information processing abilities, which may be due to the importance to efficiently process social information that can serve as tells in live poker. The observed enhancement of the inhibition of return may permit poker players to not process a localization that has already processed to save attentional resources. Further research regarding the establishment of the IOR in other forms of gambling and with non-social cues needs to be performed.

“…Speed of visual information processing during simple target detection tasks, may remain intact in the face of cannabis use [68,69], and in some cases may actually provide functional advantage for target detection because of faulty inhibition [70]. However, with more complex tasks of selective and divided visual attention, cannabis users tend to be significantly slower to detect both central and peripheral visual stimuli [48].…”

Cannabinoid Modulation of Emotion, Memory, and Motivation

This chapter is aimed at summarizing the existing literature with respect to the subjective and objective cognitive profiles associated with marijuana use. Although subjective reports of marijuana use include feelings of relaxation and increased creativity, the altered state of consciousness and reduced inhibitory and executive cognitive functions may be enough to cause impairment in daily functioning. However, a chronically high level of consumption for an extended period of time is likely to result in increased risk of developing impairments such as affective dysregulation, inefficient cognitive control, underachievement, lower estimated intellectual capacity, and increased potential for additional drug use.

Use of cannabis enhances attentional inhibition

Abstract: This is the first study to show that attentional inhibition is enhanced in cannabis users. More research is needed to determine whether greater inhibition represents an advantage or disadvantage for visual search performance of cannabis users.
