A prospective study of at risk cannabis use: Neurocognitive and neuro-imaging predictors of the course of drug use

Funding country
Netherlands
Project starting year
2008
Project ending year
2013
Area(s) of research
Determinants of drug use, Consequences of drug use, Mechanism of drug use and effects
Objectives
The current Specific Aims of this binational project are to delineate how (1) decision making, (2) working memory and (3) the underlying abnormal brain responses during performance of these tasks relate to the course of marijuana use in at-risk marijuana users, in a longitudinal, prospective fMRI study. Thus, this project extends the specific aims of the parent grant by investigating the predictive value of the same constructs considered in the specific aims of the parent grant: decision making abilities, cognitive function, and associated brain activity on the course of drug use in a group of at risk cannabis users. The Supplemental Project also extends the parent grant by including at risk users, thereby complementing the heavy user group included in the parent proposal. Thus, this proposal for a Supplemental Project is linked closely to the Specific Aims of the original parent grant, both by the constructs it studies, as well as the subject population that it includes.

Initial identified needs
To date very little is known about factors that predict the course of drug use and transition of drug use into drug abuse and dependence in the general population. At the same time knowledge about these factors are crucial for the development of effective prevention strategies. Cannabis is the most commonly used illegal drug in most countries and progression into use of other illegal drugs (ecstasy, cocaine) is frequently observed in countries regardless of the legal repercussions. Neurocognitive functions such as high impulsivity and diminished decision making predict relapse and treatment outcome in substance dependent groups. Few investigations, however, have addressed the role of neurocognitive functions on the trajectory of cannabis use and the potential progression into other drug use. We therefore propose a prospective study on two promising neurobiological mediators: neurocognitive functions (decision making and conflict monitoring) and brain function activity of relevant areas during neurocognitive performance as assessed with fMRI. Differences in the legal framework between the Netherlands and the USA constitute a unique opportunity to study the ecological validity of neurocognitive predictors of the course of high risk cannabis use. An at risk cannabis use group and a currently drug-free control group are included. Hypotheses: 1. Neurocognitive risk factors will be related to the course of drug use in at risk cannabis users. 2. Abnormal brain functioning in relevant brain areas is related to the course of drug use in at risk cannabis users. 3. The relation between cognitive deficits and the progression or de-escalation of drug use is stronger in at risk cannabis users in the Netherlands, than in a similar group in the USA, where a legal framework of negative consequences diminishes the influence of these neurobiological risk factors. Inclusion of a currently drug-free control group will provide the basis for determining whether at risk cannabis users have deficient decision making ability and associated impaired brain function.

Summary references
See publications. Summary of the project results: Partly due to the ongoing discussion regarding the addictive potential of cannabis, compared to other substances of abuse relatively little is know about the brain processes underlying regular cannabis use, abuse and dependence. The still rising treatment demands for cannabis use disorders necessitates research investigating the mechanisms underlying continued cannabis use. The heavy cannabis users described in this project used cannabis at least 10 days per month for at least 2 years, on average 5 days per week for a period of 2.5 years. This group had no treatment demands or any history with treatment, however part of the group may already be dependent on cannabis. We can generally conclude that this level of cannabis use is associated mild differences in brain structure and function compared to healthy matched controls. Moreover, differences appear strongest in heavy cannabis users with higher levels of use and problems. Heavy cannabis use was most consistently associated with altered motivational processes: cannabis cue-induced brain activity, implicit cannabis associations, and approach action tendencies towards cannabis differed between heavy cannabis users and controls. However, the results provide little evidence for behavioural impairments in cognitive control functions like decision-making and working-memory in heavy cannabis users. These findings imply that motivational processes may change relatively early in time during the course of cannabis use towards dependence, compared to cognitive control deficits. However, longitudinal studies are needed to confirm this.

Cannabis and MDMA: the human neuropharmacology of memory impairment

Funding country
Netherlands
Project starting year
2007
Project ending year

Area(s) of research
Consequences of drug use, Mechanism of drug use and effects
Objectives
The present proposal is designed to elucidate the neuropharmacological mechanisms underlying memory impairment during MDMA and cannabis intoxication. Mechanistic studies are proposed to focus on the role of glutamatergic, cholinergic and serotonergic neurotransmission in particular. Their aim is to assess whether memory impairment during intoxication with cannabis or MDMA can be blocked or reversed by pharmacological manipulations in each of these neurotransmitter systems. Successful manipulation would strongly suggest a functional role of these transmitters in memory impairment.

Initial identified needs
Cannabis and MDMA have been associated with memory impairment during intoxication. The human neuropharmacology underlying these memory deficits is largely unclear.

Initial identified needs
In the Netherlands, it is estimated that approximately 80,000 individuals may be considered as high risk cannabis users. Treatment demand for cannabis problems has strongly increased in the past decade. In the public debate, cannabis related problems have been linked with the recent doubling of the concentration of tetrahydrocannabinol (THC) in Dutch domestic grown marijuana. Previous studies have shown that variables involved in initiation of cannabis use differ from those involved in the development of cannabis dependence among users. Although factors involved in initiation of use have been extensively studied, risk factors involved in the transition from risky non-dependent use to cannabis dependence and the course of dependence, including factors related to treatment demand, are largely unknown.

Initial identified needs
The city of Lelystad (ca. 75.000 inhabitants) is an exception to the rule in the Netherlands. While other cities and towns close down coffee shops that sell cannabis, Lelystad opened its first one in 2011. This created a unique opportunity to examine the effect of a new coffee shop in a previously coffee-shop-free-zone with regard cannabis supply and cannabis-related public nuisance.

Project starting year
2008
Project ending year

Area(s) of research
Determinants of drug use
Objectives
The proposal aimed to investigate, within a population-based sample of adolescents -enriched with a high-risk sample - the following research questions: 1) Which endophenotypic characteristics are related to early onset use of nicotine, alcohol and cannabis? 2) Which endophenotypic characteristics are related to the transition from initiation of substance use to regular use of nicotine, alcohol and cannabis in adolescence? 3) Are these endophenotypic characteristics related to common and specific DNA polymorphisms? In the studies, the following endophenotypic characteristics will be examined: I. Representing reduced cognitive functions associated with behavioural disinhibition: (a) CNS inhibition, indexed by the P3 components of the ERP; (b) Reward-associated decision-making abilities. II. Representing individual differences in stress physiological responses: (c) Reactivity to stress of the hypothalamic-pituitary –adrenal (HPA) axis); (d) Reactivity to stress of the autonomic nervous system (ANS). Various interrelations among endophenotypic characteristics of each pathway, and between pathways, and between genotype and endophenotype will be examined to test their predictive value for substance use.
Scientific discipline(s) involved
Epidemiology, Psychology
Read more…
Initial identified needs
The key objective of our proposal was to examine the role of endophenotypes that explain individual resilience and vulnerability to early onset of substance use and the transition to regular use. These endophenotypes form a intermediate between the genotype and the phenotype, and can tell us more about the underlying psychobiological mechanisms leading to higher risk for adolescent substance use.

Initial identified needs
Estimates of the total volume of cannabis consumed at population level are deemed necessary for informing policy decisions both in the field of public health and supply reduction. However, estimates of total cannabis consumption rarely consider differences among different user types and variation across countries, due to a lack of (comparative) detailed data on consumption patterns.
