Cannabis enters the bloodstream within 30 seconds and reaches peak effects within 30-60 minutes. THC and CBD can be detected in the body for at least 80 days. Sativa varieties of cannabis elevate mood, increase focus, and promote talkativeness, while indica varieties have sedative effects. Cannabis binds to CB1 receptors in different brain areas, causing either heightened alertness and focus or suppression of stress and threat detection.
