There are so many different reactions you can have to marijuana. I smoke it personally without any problems. It helps my anxiety and actually helps my mood. But my ex, for example, would get paranoid when he smoked. My brother often gets anxious and can't sit still when he gets high. Know yourself, and how your brain reacts to it. Definitely weigh the pros and cons of smoking. It may be great for your friend, but perhaps not for yourself, and that's OK. Not everyone is the same. Good luck!
