However, I do want people to be aware of the fact that charcoal will absorb medications after a short time of use.
That depends on the timing. This is what drugs.com has to say about it:
Do not take Activated Charcoal with any other medicine. Take your dose of Activated Charcoal at least 2 hours before or 1 hour after a dose of any other medicine. Activated Charcoal binds to other drugs and can make them less effective, which could become dangerous.
