Does Marijuana Affect The TSH Levels?

Hello,’m a frequent marijuana smoker, as it helps me feel physically better and helps with my anxiety/adhd. Somewhere along the line in 2016, I dropped from 146 lbs to 106 lbs in the course of a month. I went and got blood work done for my thyroid to see if I possibly was struggling with underactive/overactive thyroid, as many of the signs that I’m experiencing fall under that specific diagnosis. Yet, my thyroid test came back fine with no issues. My girlfriend has read somewhere recently that active marijuana users (or recent users with use in the past 30 days or so) have affected TSH levels, which would obviously change the direct results of a test regardless of the true issue. Is this true? I have stopped smoking last week in hopes that I could go get another panel done somewhere around may 10th. Is this necessary? Or would I be able to continue smoking? I just really need to find out what’s wrong with me and I need to know if marijuana is affecting my results with the blood work. Any advice or information is appreciated!
