You would be surprised. When I am tolerant for a high dose I can vape 6 or 7 times a day which equates to around 3g of strong weed. And that would be every day. About 90g per month.
I had to get rid of my vape to cut down on the ease of smoking cuz my tolerance was such i was needing to step up to wax concentrates (and i don't wanna). I have a huge sack in front of me but needing to roll a j is juuust enough to slow me down some
i normally use a flower vape, it uses little refillable capsules that hold about .1 gram, so if i smoke ten times i know i have only smoked 1 gram, but yeah thats still a decent amount imo.
Weed can be very helpful for focus. Not necessarily very helpful for clear thinking, but it can be very good for getting started on something so that you can come back to it later when you're sober.
It’s also fantastic if you have trouble breaking out of a negative thought cycle. On stressful nights, weed is the only thing that gets my brain to finally STFU and sleep.
Doesn't always work that way for me, unfortunately. Weed often makes it impossible to avoid or ignore negative self-image problems that I'm usually constantly pushing down.
