What I find is that the common belief is that as a tolerance increases, the common held belief is just to smoke more to still get high. This worked for me for a while until I realized I'd become the epitemy of stereotypical stoner. I vaped half a gram a day through my underdog which was maybe 10 bowls throughout the day, I was high all the time and wasn't the same as my normal self when I wasn't stoned and wasn't my normal self when I was stoned. I realized that while my tolerance had gone up and the cannabinoids did effect me less, it had also numbed my cannabinoid receptors so when I wasn't stoned I was basically anti high as I call it and part of why my tolerance had gotten so high wasn't just the decrease in my sensitivity to weed, it was also my perception of high I was. Looking back even though I may not have felt super crazy high and u was calm, I was in a very altered state of mind that I had just become used to. Partially it is my fault for overdoing it, but also I feel that weed society, especially that of high school and college stoner society, pushes the idea that everything can be fixed with a bowl of weed, and it is the only drug that I have seen where using the drug to help cover problems is seen as a good thing. This at least led me to increasing my tolerance from where 1 or 2 hits got me plenty happy with my high, to 2 or 3 bowls not satisfying the itch. And this isn't to say weed ruined my life, but I was definitely overdoing it and had developed a clear phsycological addiction. I wasn't necessarily in a rush to fix it though as I said it wasn't ruining my life, but over the last year or so I've slowly reduced my consumption to about I'd guess .05-.1 grams 5-6 times a week and I'm on my way to my ultimate goal which I would guess is just 2 or 3 hits 3 or 4 times a week max.
This is obviously a very subjective post and I'm in no way saying that weed is bad. I love weed and it changed my life and made me reflect on what I was doing in a way that made me take action to make myself happier. But too much of any good thing isn't good, and too much is a very subjective thing. It just seems that my too much, and what I believe the too much of the people I see around me is a lot less than most people think it is. So here's to microdosing! Lol
