A quanto pare THC e CBD abbassano il sistema immunitario nei soggetti influenzati. Mi piacerebbe non fosse questo il caso ma ho trovato questo articolo di ricerca.

Influenza
The administration of THC could be harmful for a host infected with the influenza virus. As reported in studies on mice, THC administration after an immune challenge with influenza virus A/PR/8 resulted in increased viral loads, higher hemagglutinin 1 expression, and diminished CD4+ and CD8+ lymphocyte and macrophage recruitment into the lungs [77]. Some of these effects were observed in an opposite manner when CB1 and CB2 knockout mice were infected, i.e., showing increased CD4+ lymphocyte recruitment, IFN-γ levels, and lung inflammation, higher than in control WT mice [78]. Other immune parameters affected include cytokine secretion by CD4+ T cells and NK cells, besides a lower overall percentage of subpopulations of antigen-presenting cells present in the lungs of infected mice [79]. The observed results demonstrate that THC administration diminishes the immune response against the influenza virus.
