Scalp Scars Tingle When Smoking Pot

I have sustained about 4 scars to the back of the head. One scar is about 2 inches long and 1/2 inch thick. I have been very emotionaly and physically impacted by this. But my question is about a tingling sensation I have right above my most profound scar. It is very irritating, and becomes quite bothersome when I smoke pot. And at times I fell like I’m losing hair. Could i be losing hair and is it a result of my injuries or smoking? Why does it feel like that when I smoke, I’ve never had a problem with this until the accident.

Some people have increased sensitivity after being injured, which can irritate certain nerves. As I’m sure you’re aware, Marijuana will alter a person’s state of mind and may enhance certain sensations while decreasing others. People experience different sensations in the scarred areas when a nerve is severed or injured. As to whether pot is causing you to lose your hair, please see: Marijuana and Hair Loss
