One study showed that selective down-regulation of cannabinoid-1 (CB1) receptors in several cortical brain regions in long-term marijuana smokers was correlated with years of cannabis smoking and was reversible after 4 weeks of abstinence. The primary disadvantage of using longitudinal studies for research is that long-term research increases the chances of unpredictable outcomes.

Advantages and disadvantages. 17 Longitudinal Study Advantages and Disadvantages. Research is a careful and detailed study into a specific problem, concern, or issue using the scientific method. For example, if the study is inverstigating occupational lung cancer rates, information about workers smoking habits may not be available. If the same people cannot be found for a study update, then the research ceases. Disadvantages: Missing data: Exposure status may not be clear, because important data may not have been collected in the first place. Disadvantages Of Thematic Analysis: Plenty more investigation is necessary. 15 Changes in CB1 receptors were not seen in subcortical regions.
