Brief Summary:
This study evaluates the health condition and its evolution with time of Cannabis consumers in the Canadian population.

Condition or disease Intervention/treatment
Cannabis Use Old Age Health Risk Other: Observational

Detailed Description:

In Canada, legalization of recreational use is likely to have decreased the perception of risks associated with Cannabis use, and means that the reported adverse effects of Cannabis are not so important, suggesting that Cannabis may be useful for their illness as an alternative or complementary therapeutic.

More Canadian physicians prescribed Cannabis for their patients. Both Recreational and medical use of Cannabis increase and will continue to grow up in the next coming years. Regardless, the typology of Cannabis use, more information on the health condition of Cannabis consumers may be helpful for the medical prescription of Cannabis, in particular in older adults who are more at risk of side effects.

Intervention Details:
  • Other: Observational
    People who are enrolled in the Canadian Longitudinal Study on Aging. Participants undergo repeated waves of the same standardized data collection every three years. All participants are also contacted by telephone 18 months after baseline assessment to complete the Maintaining Contact Questionnaire.

Primary Outcome Measures :
  1. Neurocognitive disorder [ Time Frame: around 20 years ]
    The decrease of cognitive function changes the activities of daily living to older adults. Instrumental Activities of Daily Living Scale ( IADLs) will be used to assess independent living skills to people who are a diagnosis of mild cognitive impairment. A summary score range from 0 ( low function, dependent) to 8 ( high function, independent) will be given to each participant based on their daily activities.

Secondary Outcome Measures :
  1. Depression [ Time Frame: around 20 years ]
    It will be used the Centre for Epidemiologic Studies-Depression Scale (CES-D) that rates how often over the past week people experience symptoms that are associated with depression. In scoring the Center for Epidemiologic Studies Depression Scale, a value of 0,1,2,3 is assigned to a response based on the emotional feelings that the participants have.
