start vaping, using a bag vape like the herbalaire or the volcano will definitely change the way you use cannabis and thus change your tolerance.
with vaporizing, I dont' even feel a cap out, it took about 2-3 weeks to totally get used to it, but I feel like I'm getting higher for longer periods of time, and that I can successfully medicate all day long without 'capping' out...
I know a lot of people doubt vapes but if they used a herbalaire as a full time vape for 3 weeks you'll never want to use anything else.
I only recommend it to people who don't have sparatic stashes . . . (say getting 3.5 grams every 3-4 days or something, that's too small for the vape. )
even though I do say it uses less bud, it depends on the scale at which you use it. I used to smoke 6-9 joints a day . . . . I use about 2 joints worth in an ENTIRE day with my vaporizer now. and I get much higher than I did when I was smoking.
so hopefully you come to the same conclusion I did, and hopefully many other smokers start seeing it this way because it truly does a number for your lungs, your stash, your high and well being in general.
edit: other strains do help with your tolerance and smoking, but it is MUCH more dramatic with a vaporizer. you can truly get high all day off the same strain with a vaporizer (after you're used to it). when you get another strain in the vape, it's almost overwealming how much higher you get.
