Mixing Acetaminophen (Tylenol) and Methamphetamine (meth)
Low risk, no synergy
No specific interaction is documented. Acetaminophen's main risk is dose-dependent liver injury, so the thing to watch in any combination is total daily intake across all products (roughly 4g/24h) and anything else straining the liver.
