I think people want to kill me when I smoke pot. Am I OK?

You are describing paranoia, which can happen when you smoke pot, and it can also be a symptom of mental illness. You won't know for sure which it is until you stop smoking pot.

Smoking pot is dangerous. While a lot of people don't want to hear it, it can create long-term mental problems like depression and mental confusion. It's a drug. It's not mother's milk. It can damage your brain. Also, it is illegal even though a lot of people have convinced themselves it's no big deal. Getting caught and charged will create a permanent record that will haunt you and create big problems for the rest of your life.

Stop smoking pot and your life will get better. If you still have these episodes of paranoia, make an appointment to see a psychiatrist and get it checked out.
