i hear things from different people, i wish there was a sure way to tell. I am around weed so much its going to drive me insane not being able to smoke. Every sign that points to it also has other explainations. Like i broke out in hives only around my neck, but i noticed it a week later after shaving my beard- could be razer burn. I broke out in a rash on my face, i have hiked 5 times in the past 2 weeks, could be posion ivy, which im allergic to. I get high really easy, could just be a one-hit wonder. I rubed weed on my skin, didnt break out. My teeth hurt when i smoke, or more noticable the next morning, could just be my wisdom teeth. It doesnt seem like its hard to breathe when im high, i could have just freaked out the other night, which also could have gave me the head ach i got while high, i just dont know. Its really bothering me, like i cant even concentrate cause its on my mind, freaking me out, i just have to know for sure.
