Early smoking onset linked to higher risk of cannabis use

Young people who start smoking at an early age have a much higher risk of starting to use cannabis by the time they turn 17. Risk factors that increase the likelihood of starting to smoke include externalising problem behaviours such as impulsiveness. Smoking, in turn, is a significant risk factor for cannabis use. These results have been confirmed in a project researching smoking at an early age and externalising behaviour as predictors of drug use.

New research published in BioMed Central's open access journal Biology of Sex Differences reinforces this position by showing that the motivation of female rats to work for cocaine is much higher than males.

Anomalies causing motivational deficiencies may also cause ADHD

Until now, attention-deficit/hyperactivity disorder (ADHD) was related to alterations in the brain affecting attention and cognitive processes. Researchers at Universitat Autònoma de Barcelona and the Vall d'Hebron University Hospital for the first time have discovered anomalies in the brain's reward system related to the neural circuits of motivation and gratification. In children with ADHD, the degree of motivation when carrying out an activity is related to the immediacy with which the objectives of the activity are met. This would explain why their attention and hyperactivity levels differ depending on the tasks being carried out.
