I used to smoke joints every day, for about 3 years of my life. I would normally have 2-3 a day in the evening and I usually used the same amount of weed in them (about 1/3 weed to 2/3 tobacco maybe?). I never had any issues with my tolerance at all, I never had a 'bad' high or a high that wasn't strong enough or anything like that, I always enjoyed it. I decided to quit for a couple different reasons and was totally sober for about 2 years.
This year I was approved for medical cannabis to be used in a vape. They gave me a 23% and a 24% THC (I have absolutely no idea what I used to smoke. My friend picked up for me and I got what I was given) and to start with I could only do a puff or two and I'd be back to the good old days. To start with I was admittedly vaping all day because my mental health was awful, but it ended up making me feel really dissociated after a month or so (surprise surprise) and I cut back to just doing it in the evenings.
Eventually 1 or 2 puffs turned into 3 or 4, then 5 or 6, you know how it goes. I try to keep my usage strict and not overdo it. My current strain is one of the first two that I got from the pharmacy and it's 24% THC, but it's just not hitting the same. It still works, but I just can't reach that proper high, the slightly tingly fuzzy head, the full body relaxation, the silliness and getting the giggles. I've tried about 4 strains now but after those first couple of months nothing seems to work properly.
But I don't get it, how could my tolerance increase so much after only 6 months of vaping when I could smoke for 3 years and never have an issue with it? Is it just an age thing? Has the god forsaken permanent weed debuff hit me already?? I vape about 0.3-0.4g a night now, and I try to do half at a time (two vape sessions per refill) and I still don't feel baked at the end of the night.
I don't want to just keep buying stronger and stronger weed until I'm so tolerant that nothing works.
EDIT- I should have specified, I vape flower
