"If marijuana is so good for you why does it make you cough?"

If marijuana is so good for you why does it make you cough?

This is a question I was asked and in fairness, on the face of it it seems a reasonable one. However, it is very misguided. Coughing isn't necessarily indicative of marijuana being unhealthy. Coughing is just a bodily response to your airway being irritated.

Irritated, you say? Well, see it's bad for you. You just said it's irritating to the airway!

Irritation is in no way a reliable indicator of something being unhealthy. Spicy foods can cause tremendous pain and irritation while being eaten but time and again science has proven spicy foods to offer a wide range of health benefits. Stretching your muscles, lifting weights, running until your body feels like it's on fire or receiving a deep tissue massage are painful and/or irritating to the body while also being extremely good for you. Marijuana is much the same.

Of course, everything has negatives attached and everything can be done too much but moderate, intelligent use of marijuana is at worst a benign undertaking and at best a very positive one with a myriad number of health benefits (both mental and physical health).
