Question:

I`m worried because I used meth before an operation on Monday. What can go wrong during the procedure because I used meth? 

Answer:

The fact that you’re writing in about this suggests that you survived the experience. Being intoxicated before surgery and anesthesia is still not a good idea of course. Meth – or crystal methamphetamine – is a drug with serious potential harmful effects, including stroke and heart attack. This drug activates the sympathetic nervous system, increasing blood pressure and heart rate and can interact unpredictably with certain medications used in anesthesia. Meth also causes severe damage to teeth.
