Currently, cannabis is making waves and gaining traction among different age groups. Many now ask if their regular use of the drug could adversely impact life-saving plasma donations. A straightforward answer to this is that cannabis users can give out as much-needed blood to people in need as possible. Additionally, they can decide to store their blood and source plasma in blood banks for future use. However, this doesn't mean you can show up at the hospital when high. The healthcare workers have directives to turn intoxicated donors away.
